NOTE: These tables should only be used for race/ethnicity comparisons. See Table 10 for age-specific cases and rates and Tables 3-5 for total and sex-specific cases and rates.

Cases in the 0–4 age group may include cases due to perinatal transmission.

In 2011, race/ethnicity was unknown (i.e., unknown, missing, or invalid data values) for 26.1% of reported chlamydia cases.

UNK = Unknown
