Orange County, California

Members of the Tongva, Juaneño, and Luiseño Native American groups long inhabited the area. After the 1769 expedition of Gaspar de Portolà, a Spanish expedition led by Junipero Serra named the area Valle de Santa Ana (Valley of Saint Anne).[9] On November 1, 1776, Mission San Juan Capistrano became the area's first permanent European settlement. Among those who came with Portolá were José Manuel Nieto and José Antonio Yorba. Both these men were given land grants—Rancho Los Nietos and Rancho Santiago de Santa Ana, respectively. The Nieto heirs were granted land in 1834. The Nieto ranches were known as Rancho Los Alamitos, Rancho Las Bolsas, and Rancho Los Coyotes. Yorba heirs Bernardo Yorba and Teodosio Yorba were also granted Rancho Cañón de Santa Ana (Santa Ana Canyon Ranch) and Rancho Lomas de Santiago, respectively. Other ranchos in Orange County were granted by the Mexican government during the Mexican period in Alta California.[10]

Saint Junípero Serra y Ferrer and the early components of the Portolá Expedition arrived in modern-day San Diego, south of the present-day Orange County, in mid-late 1769. During these early Mission years, however, the early immigrants continued to rely on imports of both Mexican-grown and Spanish-grown wines; Serra repeatedly complained of the process of repeated, labored import.[11]

Per Thomas Pinney's definitive 1989 work A History of Wine in America:

"The first clear reference to the planting of grapes at a California mission comes from San Juan Capistrano in 1779, ten years after the arrival of the Franciscans in California. These vines might have produced a small crop as early as 1781, but the evidence points to 1782 as the likeliest date for California's first vintage. In an original and important essay, Roy Brady has not only established this chronology for the first California wine but has also plausibly identified the means whereby the vines were first brought to the state; they came, he suggests, in May 1778 on board the supply ship San Antonio under the command of Don José Camacho. If so, the state has a neglected benefactor long overdue for public recognition. The beginning made at San Juan Capistrano . . . grew, in time, to include the entire system of missions, with uneven but substantial success."[11]

Viticulture became an increasingly important crop in Los Angeles and Orange Counties through the subsequent decades. By the 1850s, the regions supported more than 100 vineyards.[12] In 1857, Anaheim was founded by 50 German-Americans (with lineage extending back to Franconia) in search of a suitable grape-growing region.[13] This group purchased a 1,165 acres (4.71 km2) parcel from Juan Pacifico Ontiveros's Rancho San Juan Cajon de Santa Ana for $2 per acre and later formed the Anaheim Vineyard Company.[14][12] With surveyor George Hansen, two of the wine colony's founders, John Frohling and Charles Kohler, planted 400,000 grapevines along the Santa Ana River; by 1875, "there were as many as 50 wineries in Anaheim, and the city’s wine production topped 1 million gallons annually."[12] Despite later afflictions of both Phylloxera and Pierce's Disease, wine growing is still practiced.[15]

A severe drought in the 1860s devastated the prevailing industry, cattle ranching, and much land came into the possession of Richard O'Neill, Sr.,[16] James Irvine and other land barons. In 1887, silver was discovered in the Santa Ana Mountains, attracting settlers via the Santa Fe and Southern Pacific Railroads.

Los Angeles County before the secession of Orange County in 1889

After several failed attempts in previous sessions, the California legislature passed a bill authorizing the portion of Los Angeles County south of Coyote Creek to hold a referendum on whether to remain part of Los Angeles County or to secede and form a new county to be named “Orange” as directed by the legislature. Such referendum required a 2/3 vote for secession to take place, and subsequently on June 4, 1889, the residents south of Coyote Creek voted 2,509 to 500 in favor of secession. After such referendum, Los Angeles County filed three lawsuits in the courts to stall and stop the secession from occurring, but such attempts were futile. On July 17, 1889, a second referendum was held south of the Coyote Creek to determine if the county seat of the to-be county to be in either Anaheim or Santa Ana, along with an election for every county officer. In the end, Santa Ana defeated Anaheim in such referendum. With the referendum having taken place, the County of Orange was officially incorporated on August 1, 1889, as prescribed by state law.[17] Since the date of the incorporation of the county, the only geographical changes to have occurred which affected Orange County was when the County and Los Angeles County agreed to trade land around Coyote Creek to adjust the border of the two counties to conform with city blocks.

The county is said to have been named for the citrus fruit in an attempt to promote immigration by suggesting a semi-tropical paradise – a place where anything could grow.[18]

Other citrus crops, avocados, and oil extraction were also important to the early economy. Orange County benefited from the July 4, 1904, completion of the Pacific Electric Railway, a trolley connecting Los Angeles with Santa Ana and Newport Beach. The link made Orange County an accessible weekend retreat for celebrities of early Hollywood. It was deemed so significant that Pacific City changed its name to Huntington Beach in honor of Henry E. Huntington, president of the Pacific Electric and nephew of Collis Huntington. Transportation further improved with the completion of the State Route and U.S. Route 101 (now mostly Interstate 5) in the 1920s.

Agriculture, such as that involving the boysenberries made famous by Buena Park native Walter Knott, began to decline after World War II. However, the county's prosperity soared during this time. The completion of Interstate 5 in 1954 helped make Orange County a bedroom community for many who moved to Southern California to work in aerospace and manufacturing.[19] Orange County received a further boost in 1955 with the opening of Disneyland.

In 1969, Yorba Linda-born Orange County native Richard Nixon became the 37th President of the United States.

In the late 1970s, Vietnamese and Latino immigrants began to populate Orange County.[20]

In the 1980s, Orange County had become the second most populous county in California as the population topped two million for the first time.

In 1994, an investment fund meltdown led to the criminal prosecution of treasurer Robert Citron. The county lost at least $1.5 billion through high-risk investments in bonds. The loss was blamed on derivatives by some media reports.[21] On December 6, 1994, the County of Orange declared Chapter 9 bankruptcy,[21] from which it emerged on June 12, 1996.[22] The Orange County bankruptcy was at the time the largest municipal bankruptcy in U.S. history.[21]

Land use conflicts arose between established areas in the north and less developed areas in the south. These conflicts were over issues such as construction of new toll roads and the repurposing of a decommissioned air base. El Toro Marine Corps Air Station was designated by a voter measure in 1994 to be developed into an international airport to complement the existing John Wayne Airport. But subsequent voter initiatives and court actions have caused the airport plan to be permanently shelved. It has developed into the Orange County Great Park and housing.[23]

Huntington Beach and Fountain Valley from over Costa Mesa

Orange County is sometimes divided into northern and southern regions. There are significant political, demographic, economic and cultural distinctions between North and South Orange County.[26] A popular dividing line between the two regions is the Costa Mesa Freeway.

North Orange County, including Anaheim, Fullerton, Garden Grove and Santa Ana, was the first part of the county to be developed and is culturally closer to neighboring Los Angeles County. This region is more Hispanic (mostly Mexican) and Asian (predominantly Vietnamese and Korean),[27] more densely populated (Santa Ana is the fifth most densely-populated city in the United States with a population of over 200,000), younger, less wealthy and with higher unemployment. It has more renters and fewer homeowners and generally votes Democratic. There are notable exceptions to these general trends, such as strongly Republican Yorba Linda and affluent Anaheim Hills, North Tustin, and Villa Park.[26] North Orange County is predominantly flat, giving way to the Santa Ana Mountains in the Northeast.

South Orange County is wealthier, more residential, more Republican, predominantly non-Hispanic white and more recently developed. Irvine, the largest city in the region, is an exception to some of these trends, being not only a major employment center, but also a major tech hub and education center with UCI. Furthermore, the city is an Asian plurality (both South and East Asian), and votes reliably Democratic in recent years. South Orange County almost always includes Irvine,[28] Newport Beach, and the cities to their southeast, including Lake Forest, Laguna Beach, Mission Viejo, and San Clemente. Alternatively, Irvine and Newport Beach are sometimes seen as Central Orange County, acting as a transition zone between north and south; when this viewpoint is taken Tustin is also considered to be in central Orange County. Costa Mesa is sometimes included in South County,[29] although it is located predominantly to the west of the Costa Mesa Freeway and is part of the even street grid network of north Orange County.[30] Irvine is located in a valley defined by the Santa Ana Mountains and the San Joaquin Hills, while much of South Orange County is very hilly.

Another region of Orange County is the Orange Coast, which includes the six cities bordering the Pacific Ocean. These are, from northwest to southeast: Seal Beach, Huntington Beach, Newport Beach, Laguna Beach, Dana Point and San Clemente, although Seal Beach is sometimes viewed as an extension of neighboring Long Beach in Los Angeles County.

Older cities like Santa Ana, Anaheim, and Fullerton have traditional downtowns dating back to the 19th century, with Downtown Santa Ana being the home of the county, state and federal institutions. However, far more commercial activity is concentrated in clusters of newer commercial development are found in the county's edge cities, the three largest being

• along Interstate 5 between Disneyland and Downtown Santa Ana
• South Coast Plaza to the Irvine Business Complex, and at
• Irvine Spectrum

Major facilities in the Anaheim–Santa Ana edge city, plus the locations of the adjacent downtowns

MainPlace Mall

A contiguous strip of commercial development (an edge city) stretches from Disneyland through to MainPlace Mall along the I-5 Santa Ana Freeway,[31][32][33][34][35] straddling the city limits of Anaheim, Garden Grove, Orange, and Santa Ana, and in fact stretching between the original downtowns of those four cities.

Entertainment and cultural facilities include Disneyland Resort, Angel Stadium, Christ Cathedral (formerly Crystal Cathedral), City National Grove of Anaheim - a live concert venue, Discovery Cube Orange County, the Honda Center - home to the Anaheim Ducks of the NHL (National Hockey League), and the Anaheim Convention Center. Health care facilities include CHOC (Children's Hospital of Orange County), Kaiser Permanente Health Pavilion (Anaheim), St. Joseph Hospital (Orange), and the UCI Medical Center.

Retail complexes include Anaheim GardenWalk, Anaheim Marketplace (claiming to be the largest indoor swap meet in Orange County with more than 200 vendors), MainPlace Mall, Orange Town & Country, and The Outlets at Orange, originally a mall named "The City" which was the centerpiece of a planned, 1970s mixed-use development by the same name. There is commercial strip-style development including big box retailers along West Chapman Avenue in Orange (Marshalls, Ralphs), along Harbor Boulevard in Garden Grove (Burlington, Ross Dress for Less), and around Harbor Blvd. and Chapman Ave. in Anaheim (Target).

Major hotels line Harbor Boulevard from Disneyland south to Garden Grove: Grand Legacy at the Park, Hilton, Marriott, Courtyard, DoubleTree Suites, Hampton Inn, Hilton Garden Inn, Homewood Suites, Embassy Suites, Residence Inn, Hyatt Regency, Marriott Suites, Sheraton, and the Great Wolf Lodge. The Orange County Transit Authority studied the corridor as the possible route for a streetcar, a proposal that was dropped in 2018 due to opposition from Anaheim and other city governments.[36]

In addition to suburban-style apartment complexes, Anaheim's Platinum Triangle is undergoing transformation from a low-density commercial and industrial zone into a more urban environment with high-density housing, commercial office towers, and retail space. Anaheim envisions it as a "downtown for Orange County".[37] The 820 acres (330 ha) area undergoing this large-scale redevelopment includes the city's two major sports venues, the Honda Center and Angel Stadium of Anaheim.[38]

Hispanic or Latino of any race were 1,012,973 persons (33.7%).[54]

The Hispanic and Latino population is predominantly of Mexican origin; this group accounts for 28.5% of the county's population, followed by Salvadorans (0.8%), Guatemalans (0.5%), Puerto Ricans (0.4%), Cubans (0.3%), Colombians (0.3%), and Peruvians (0.3%).[55] Santa Ana with its population reportedly 75 percent Hispanic/Latino, is among the most Hispanic/Latino percentage cities in both California and the U.S., esp. of Mexican-American descent.[56]

Among the Asian population, 6.1% are Vietnamese, followed by Koreans (2.9%), Chinese (2.7%), Filipinos (2.4%), Indians (1.4%), Japanese (1.1%), Cambodians (0.2%) Pakistanis (0.2%), Thais (0.1%), Indonesians (0.1%), and Laotians (0.1%).[55] According to KPCC in 2014, Orange County has the largest proportion of Asian Americans in Southern California, where one in five residents are Asian American.[57] There is also a significant Muslim population in the county.[58]

As of the census[59] of 2000, there were 2,846,289 people, 935,287 households, and 667,794 families living in the county, making Orange County the second most populous county in California. The population density was 1,392/km² (3,606/sq mi). There were 969,484 housing units at an average density of 474/km² (1,228/sq mi). The racial makeup of the county was 64.8% White, 13.6% Asian, 1.7% African American, 0.7% Native American, 0.3% Pacific Islander, 14.8% from other races, and 4.1% from two or more races. 30.8% were Hispanic or Latino of any race. 8.9% were of German, 6.9% English and 6.0% Irish ancestry according to Census 2000. 58.6% spoke only English at home; 25.3% spoke Spanish, 4.7% Vietnamese, 1.9% Korean, 1.5% Chinese (Cantonese or Mandarin) and 1.2% Tagalog.

In 1990, still according to the census[60] there were 2,410,556 people living in the county. The racial makeup of the county was 78.6% White, 10.3% Asian or Pacific Islander, 1.8% African American, 0.5% Native American, and 8.8% from other races. 23.4% were Hispanic or Latino of any race.

The average household size was 3.00 and the average family size was 3.48.

Ethnic change has been transforming the population. By 2009, nearly 45 percent of the residents spoke a language other than English at home. Whites now comprise only 45 percent of the population, while the numbers of Hispanics grow steadily, along with Vietnamese, Korean and Chinese families. The percentage of foreign-born residents jumped to 30 percent in 2008 from 6 percent in 1970. The mayor of Irvine, Sukhee Kang, was born in Korea, making him the first Korean-American to run a major American city. “We have 35 languages spoken in our city,” Kang observed.[61] The population is diverse age-wise, with 27.0% under the age of 18, 9.4% from 18 to 24, 33.2% from 25 to 44, 20.6% from 45 to 64, and 9.9% 65 years of age or older. The median age is 33 years. For every 100 females, there were 99.0 males. For every 100 females age 18 and over, there were 96.7 males.

The median income for a household in the county was $61,899, and the median income for a family was $75,700 (these figures had risen to $71,601 and $81,260 respectively as of a 2007 estimate[62]). Males had a median income of $45,059 versus $34,026 for females. The per capita income for the county was $25,826. About 7.0% of families and 10.3% of the population were below the poverty line, including 13.2% of those under age 18 and 6.2% of those age 65 or over.

Residents of Orange County are known as "Orange Countians".[63]

Also, Knotts Berry Farm gets about 7 million visitors annually and is located in the city of Buena Park. The Anaheim Convention Center holds many major conventions throughout the year. Resorts within the Beach Cities receive visitors throughout the year due to their close proximity to the beach, biking paths, mountain hiking trails, golf courses, shopping and dining.

As recently as the 1990s, award-winning restaurants in Orange County consisted mostly of national chain restaurants with traditional American or Tex-Mex comfort food. In the late 1990s, Tim and Liza Goodell with chef Florent Marneau, and David Wilhelm, established culinary restaurant groups featuring nouvelle cuisine, gourmet burgers and more. The Orange County Register states that the "tipping point" came in 2007 when Marneaus founded Marché Moderne (since moved to Crystal Cove), and Top Chef chef Amar Santana opened a branch of Charlie Palmer (closed 2015),[70] both at South Coast Plaza. Santana followed opening restaurants Broadway in Laguna Beach and Vaca in Costa Mesa. Other Top Chef chefs followed with their own restaurants including Brian Huskey (Tackle Box), Shirley Chung (Twenty Eight), Jamie Gwen of Cutthroat Kitchen, and from The Great Food Truck Race, Jason Quinn (Playground), who also opened three stands at the 4th Street Market[71] food hall in Downtown Santa Ana in 2016.[72]

Food halls with gourmet vendors include the 42,000-square-foot (3,900 m²) Anaheim Packing District, the 4th Street Market in Downtown Santa Ana, Lot 579 in Huntington Beach, Trade Food Hall in Irvine,[73] OC Mix in Costa Mesa, and The Source OC in Buena Park.[74]

Each of the five members of the Board of Supervisors is elected from a regional district, and together, the board oversees the activities of the county's agencies and departments and sets policy on development, public improvements, and county services. At the beginning of each calendar year, the Supervisors select a Chair and Vice Chair amongst themselves. The Chair presides over board meetings, and the Vice Chair presides when the Chair is not present. The Board appoints the Clerk of the Board of Supervisors, the County Counsel, the Performance Audit Director, and the Director of the Office of Independent Review. The Board also appoints the County Executive Officer to act as the chief administrative officer of the county and the manager of all agencies and departments not under the sole jurisdiction of an elected county official nor the sole jurisdiction of one of the four aforementioned officers appointed by the Board.[97]

As of January 2021, the members of the Orange County Board of Supervisors are:[93][94][97]

• District 1: Andrew Do, Republican (since February 3, 2015)
• District 2: Katrina Foley, Democrat (since March 23, 2021)
• District 3: Donald P. Wagner, Republican (since March 27, 2019)
• District 4: Doug Chaffee, Democrat (since January 7, 2019)
• District 5: Lisa Bartlett, Republican (since December 2, 2014)

The County Department of Education is wholly separate from the County government and is jointly overseen by the elected County Superintendent of Schools and the five-member Orange County Board of Education, whose trustees are popularly elected from five separate trustee areas.[96]

As of January 2021, the six elected officials overseeing the Orange County Department of Education are:[94][98]

• Trustee Area 1: Jorge Valdes, Republican
• Trustee Area 2: Mari Barke, Republican

On July 12, 2010, it was revealed that former Sheriff Mike Carona received over $215,000 in pension checks in 2009, despite his felony conviction.[99] A 2005 state law denied a public pension to public officials convicted of wrongdoing in office, however, that law only applied to benefits accrued after December 2005. Carona became eligible for his pension at age 50, and is also entitled, by law, to medical and dental benefits.[100][101] It was noted that the county's retirement system faces a massive shortfall totaling $3.7 billion unfunded liabilities, and Carona was one of approximately 400 retired Orange County public servants who received more than $100,000 in benefits in 2009.[102] Also on the list of those receiving extra-large pension checks is former treasurer-tax collector Robert Citron, whose investments, which were made while consulting psychics and astrologers, led Orange County into bankruptcy in 1994.[103]

Citron, a Democrat, funneled billions of public dollars into questionable investments, and at first the returns were high and cities, schools and special districts borrowed millions to join in the investments. But the strategy backfired, and Citron's investment pool lost $1.64 billion. Nearly $200 million had to be slashed from the county budget and more than 1,000 jobs were cut. The county was forced to borrow $1 billion.[104]

The California Foundation for Fiscal Responsibility filed a lawsuit against the pension system to get the list. The agency had claimed that pensioner privacy would be compromised by the release. A judge approved the release and the documents were released late June 2010. The release of the documents has reopened debate on the pension plan for retired public safety workers approved in 2001 when Carona was sheriff.[105]

Called "3 percent at 50," it lets deputies retire at age 50 with 3 percent of their highest year's pay for every year of service. Before it was approved and applied retroactively, employees received 2 percent.[106] "It was right after Sept. 11," said Orange County Supervisor John Moorlach. "All of a sudden, public safety people became elevated to god status. The Board of Supervisors were tripping over themselves to make the motion." He called it "one of the biggest shifts of money from the private sector to the public sector." Moorlach, who was not on the board when the plan was approved, led the fight to repeal the benefit. A lawsuit, which said the benefit should go before voters, was rejected in Los Angeles County Superior Court in 2009 and is now under appeal.[105] Carona opposed the lawsuit when it was filed, likening its filing to a "nuclear bomb" for deputies.

From the mid-20th century until the 2010s, Orange County was known as a Republican stronghold and consistently sent Republican representatives to the state and federal legislatures — so strongly so, that Ronald Reagan described it as the place that "all the good Republicans go to die."[109] Republican majorities in Orange County helped deliver California's electoral votes to Republican nominees Richard Nixon in 1960, 1968, and 1972; Gerald Ford in 1976; Reagan in 1980 and 1984; and George H. W. Bush in 1988. It was one of five counties in the state that voted for Barry Goldwater in 1964.

In 1936, Orange County gave Franklin D. Roosevelt a majority of its presidential vote. The Republican nominee won Orange County in the next 19 presidential elections, until Hillary Clinton won the county with a narrow majority in 2016.[116][117] In 2020, Joe Biden further improved slightly on Clinton's 2016 margin of victory.[118][119]

The Republican margin began to narrow in the 1990s and 2000s as the state trended Democratic until the mid- to late-2010s when it voted for the Democratic Party in 2016 and in 2018, when the Democratic party won every United States House District anchored in the county, including four that had previously been held by Republicans.[120] This prompted media outlets to declare Orange County's Republican leanings "dead", with the Los Angeles Times running an op-ed titled, "An obituary to old Orange County, dead at age 129."[109][110][111][112][121] While Republicans were able to recapture two of the seven U.S. House seats in Orange County in 2020, Democrats continue to hold the other five, with Biden winning the county by a slightly greater margin than Clinton and a majority of the votes in each of the seven congressional districts.[119] Republicans still carry more weight at the local level, and in 2020 for the State Assembly elections, they won 50.2% of the vote and four out of seven seats of the county.[122]

For the 117th United States Congress in the United States House of Representatives, Orange County is split between seven congressional districts:[125]

• California's 38th congressional district, represented by Democrat Linda Sánchez,
• California's 39th congressional district, represented by Republican Young Kim,
• California's 45th congressional district, represented by Democrat Katie Porter,
• California's 46th congressional district, represented by Democrat Lou Correa,
• California's 47th congressional district, represented by Democrat Alan Lowenthal,
• California's 48th congressional district, represented by Republican Michelle Steel, and
• California's 49th congressional district, represented by Democrat Mike Levin.

The 39th, 45th, 46th, and 48th districts are all centered in Orange County. The 38th and 47th have their population centers in Los Angeles County, while the 49th is primarily San Diego County-based.

In the California State Senate, Orange County is split into 5 districts:[126]

• the 29th Senate District, represented by Democrat Josh Newman,
• the 32nd Senate District, represented by Democrat Bob Archuleta,
• the 34th Senate District, represented by Democrat Tom Umberg,
• the 36th Senate District, represented by Republican Patricia Bates, and
• the 37th Senate District, represented by Democrat Dave Min.

In the California State Assembly, Orange County is split into 7 districts:[126]

• the 55th Assembly District, represented by Republican Phillip Chen,
• the 65th Assembly District, represented by Democrat Sharon Quirk-Silva,
• the 68th Assembly District, represented by Republican Steven Choi,
• the 69th Assembly District, represented by Democrat Tom Daly,
• the 72nd Assembly District, represented by Republican Janet Nguyen,
• the 73rd Assembly District, represented by Republican Laurie Davies, and
• the 74th Assembly District, represented by Democrat Cottie Petrie-Norris.

According to the California Secretary of State, as of February 10, 2019, Orange County has 1,591,543 registered voters. Of these, 34% (541,711) are registered Republicans, and 33.3% (529,651) are registered Democrats. An additional 28.5% (453,343) declined to state a political party.[113]

Orange County has produced such notable Republicans as President Richard Nixon (born in Yorba Linda and lived in Fullerton and San Clemente), U.S. Senator John F. Seymour (previously mayor of Anaheim), and U.S. Senator Thomas Kuchel (of Anaheim). Former Congressman Christopher Cox (of Newport Beach), a White House counsel for President Reagan, is also a former chairman of the U.S. Securities and Exchange Commission. Orange County was also home to former Republican Congressman John G. Schmitz, a presidential candidate in 1972 from the ultra-conservative American Independent Party and the father of Mary Kay Letourneau. In 1996, Curt Pringle (later mayor of Anaheim) became the first Republican Speaker of the California State Assembly in decades.

While the growth of the county's Hispanic and Asian populations in recent decades has significantly influenced Orange County's culture, its conservative reputation has remained largely intact. Partisan voter registration patterns of Hispanics, Asians and other ethnic minorities in the county have tended to reflect the surrounding demographics, with resultant Republican majorities in all but the central portion of the county. When Loretta Sanchez, a Blue Dog Democrat, defeated veteran Republican Bob Dornan in 1996, she was continuing a trend of Democratic representation of that district that had been interrupted by Dornan's 1984 upset of former Congressman Jerry Patterson. Until 1992, Sanchez herself was a moderate Republican, and she is viewed as somewhat more moderate than other Democrats from Southern California.

In 2004, George W. Bush captured 60% of the county's vote, up from 56% in 2000 despite a higher Democratic popular vote statewide. Although Barbara Boxer won statewide in the simultaneously-held senate election and fared better in Orange County than she did in 1998, Republican Bill Jones defeated her in the county, 51% to 43%. While the 39% that John Kerry received is higher than the percentage Bill Clinton won in 1992 or 1996, the percentage of the vote George W. Bush received in 2004 is the highest any presidential candidate has received since 1988, showing a still-dominant GOP presence in the county. In 2006, Senator Dianne Feinstein won 45% of the vote in the county, the best showing of a Democrat in a Senate race in over four decades, but Orange was nevertheless the only Coastal California county to vote for her Republican opponent, Dick Mountjoy.

The county is featured prominently in Lisa McGirr's book Suburban Warriors: The Origins of the New American Right. She argues that its conservative political orientation in the 20th century owed much to its settlement by farmers from the Great Plains, who reacted strongly to communist sympathies, the civil rights movement, and the turmoil of the 1960s in nearby Los Angeles — across the "Orange Curtain".

In the 1970s and 1980s, Orange County was one of California's leading Republican voting blocs and a subculture of residents with "Middle American" values that emphasized capitalist religious morality in contrast to West coast liberalism.

Orange County has many Republican voters from culturally conservative Asian-American, Middle Eastern and Latino immigrant groups. The large Vietnamese-American communities in Garden Grove and Westminster are predominantly Republican; Vietnamese Americans registered Republicans outnumber those registered as Democrats, 55% to 22% as of 2007, while as of 2017 that figure is 42% to 36%. Republican Assemblyman Van Tran was the first Vietnamese-American elected to a state legislature and joined with Texan Hubert Vo as the highest-ranking elected Vietnamese-American in the United States until the 2008 election of Joseph Cao in Louisiana's 2nd congressional district. In the 2007 special election for the vacant county supervisor seat following Democrat Lou Correa's election to the state senate, two Vietnamese-American Republican candidates topped the list of 10 candidates, separated from each other by only seven votes, making the Orange County Board of Supervisors entirely Republican; Correa is first of only two Democrats to have served on the Board since 1987 and only the fifth since 1963.

Even with the Democratic sweep of Orange County's congressional seats in 2018, as well as a steady trend of Democratic gains in voter registration, the county remains very Republican downballot. In much of the county, the district's congressperson is the only elected Democrat above the county level, and in some cases the only elected Democrat above the municipal level. Generally, larger cities–those with a population over 100,000, such as Anaheim, Santa Ana, and Irvine - feature a registration advantage for Democrats, while the other municipalities still have a Republican voter registration advantage. This is especially true in Newport Beach, Yorba Linda, and Villa Park, the three cities where the Republican advantage is largest. As of February 10, 2019, the only exceptions to the former are Huntington Beach and Orange, while exceptions to the latter include Buena Park, Laguna Beach and Stanton.[113]

Similarly, despite Orange county supporting Democratic candidates for president in 2016, and 2020, there are still several smaller municipalities in the county that have continued to vote Republican for president. In addition to the aforementioned Newport Beach, Yorba Linda, and Villa Park, the cities of Huntington Beach, Dana Point, San Juan Capistrano, and San Clemente also supported Republican nominee Donald Trump for president twice.[127]

State Route 1 winds down the coast over Corona Del Mar State Beach.

Ground transportation in Orange County relies heavily on three major interstate highways: the Santa Ana Freeway (I-5), the San Diego Freeway (I-405 and I-5 south of Irvine), and the San Gabriel River Freeway (I-605), which briefly passes through northwestern Orange County. The other freeways in the county are state highways, and include the Riverside and Artesia Freeway (SR 91) and the Garden Grove Freeway (SR 22) running east–west, and the Orange Freeway (SR 57), the Costa Mesa Freeway (SR 55), the Laguna Freeway (SR 133), the San Joaquin Transportation Corridor (SR 73), the Eastern Transportation Corridor (SR 261, SR 133, SR 241), and the Foothill Transportation Corridor (SR 241) running north–south. Minor stub freeways include the Richard M. Nixon Freeway (SR 90), also known as Imperial Highway, and the southern terminus of Pacific Coast Highway (SR 1). There are no U.S. Highways in Orange County, though two existed in the county until the mid-1960s: 91 and 101. US 91 went through what is now the state route of the same number, and US 101 was replaced by Interstate 5. SR 1 was once a bypass of US 101 (Route 101A).

The bus network comprises 6,542 stops on 77 lines, running along most major streets, and accounts for 210,000 boardings a day. The fleet of 817 buses is gradually being replaced by CNG (Compressed natural gas)-powered vehicles, which already represent over 40% of the total fleet. Service is operated by OCTA employees and First Transit under contract. OCTA operates one bus rapid transit service, Bravo, on Harbor Boulevard. In addition, OCTA offers paratransit service for the disabled (OC ACCESS), also operated by MV.

Since 1992, Metrolink has operated three commuter rail lines through Orange County, and has also maintained Rail-to-Rail service with parallel Amtrak service. On a typical weekday, over 40 trains run along the Orange County Line, the 91 Line and the Inland Empire–Orange County Line. Along with Metrolink riders on parallel Amtrak lines, these lines generate approximately 15,000 boardings per weekday. Metrolink also began offering weekend service on the Orange County Line and the Inland Empire-Orange County line in the summer of 2006. As ridership has steadily increased in the region, new stations have opened at Anaheim Canyon, Buena Park, Tustin, and Laguna Niguel/Mission Viejo. Plans for a future station in Placentia are underway and is expected to be completed by 2020.

Since 1938, the Atchison, Topeka, and Santa Fe Railroad and later Amtrak, has operated the Pacific Surfliner regional passenger train route (previously named the San Diegan until 2000)[143] through Orange County. The route includes stops at eight stations in Orange County including, in northbound order, San Clemente Pier (selected trips), San Juan Capistrano, Laguna Niguel/Mission Viejo (formerly), Irvine Transportation Center, Santa Ana Regional Transportation Center, Orange Transportation Center (formerly), Anaheim Regional Transportation Intermodal Center (ARTIC), and Fullerton Transportation Center.

OC Streetcar, formerly known as the Santa Ana/Garden Grove Fixed Guideway Project, is a streetcar line connecting Downtown Santa Ana to the Depot at Santa Ana which is currently under construction and expected to open in 2023.[144] OCTA has also proposed connecting the two systems via Harbor Boulevard and the West Santa Ana Branch corridor.[145][146] Plans for a streetcar for Harbor Boulevard in Fullerton, Anaheim, and Garden Grove — the Anaheim Rapid Connection — were shelved in 2018.

A car and passenger ferry service, the Balboa Island Ferry, comprising three ferries running every five minutes, operates within Newport Harbor between Balboa Peninsula and Balboa Island in Newport Beach. The Catalina Flyer connects the Balboa Peninsula to Avalon with daily round-trip passage through about nine months of the year. The Catalina Express connects Dana Point to Avalon (with departures from two greater Long Beach ports also connecting to Two Harbors).

Orange County's only major airport is John Wayne Airport; its abbreviation (SNA) refers to Santa Ana, the closest large town in the early 20th century. The airport is located in unincorporated territory surrounded by Newport Beach, Costa Mesa, and Irvine. On destination monitors with flights to SNA, the airport is usually described as "Orange County, CA". In 2014, its Thomas F. Riley Terminal handled over 9 million passengers annually and as of 2019, seven airline brands provide scheduled service.

These communities are outside city limits in unincorporated county territory.

Orange County has a history of large planned communities. Nearly 30 percent of the county was created as master planned communities, the most notable being the City of Irvine, Coto de Caza, Anaheim Hills, Tustin Ranch, Tustin Legacy, Ladera Ranch, Talega, Rancho Santa Margarita, and Mission Viejo. Irvine is often referred to as a model master-planned city because its original seven villages (College Park, The Colony, The Ranch, Culverdale, The Racket Club, University Park, and Turtle Rock) were laid out by the Irvine Company of the mid-1960s before it was bought by a group of investors including Donald Bren.
