^a Estimated numbers resulted from statistical adjustment that accounted for reporting delays and missing risk-factor information, but not for incomplete reporting. Rates are per 100,000 population. Rates by race/ethnicity are not provided because U.S. census information is limited for U.S. dependent areas. Rates not calculated by transmission category because of the lack of denominator data.

^b From the beginning of the epidemic through 2008.

^c Includes Asian/Pacific Islander legacy cases (see Technical Notes).

^d Hispanics/Latinos can be of any race.

^e Heterosexual contact with a person known to have, or to be at high risk for, HIV infection.

^f Includes hemophilia, blood transfusion, perinatal exposure, and risk factor not reported or not identified.

^g Includes hemophilia, blood transfusion, and risk factor not reported or not identified.

^h Because column totals for estimated numbers were calculated independently of the values for the subpopulations, the values in each column may not sum to the column total.

ⁱ Includes persons of unknown race/ethnicity.
