Basic Statistics

AIDS Diagnoses

In 2009, the estimated number of persons diagnosed with AIDS in the United States and 5 U.S. dependent areas was 34,993. Of these, 34,247 were diagnosed in the 50 states and the District of Columbia and 747 were diagnosed in the dependent areas. In the 50 states and the District of Columbia, 25,587 AIDS diagnoses were among adult and adolescent males, 8,647 were among adult and adolescent females, and 13 diagnoses were among children under age 13 years.

The cumulative estimated number of AIDS diagnoses through 2009 in the United States and dependent areas was 1,142,714 Of these, 1,108,611 were diagnosed in the 50 states and the District of Columbia and 34,103 were diagnosed in the dependent areas. In the 50 states and the District of Columbia, 878,366 cumulative AIDS diagnoses were among adult and adolescent males, 220,795 were among adult and adolescent females, and 9,448 were among children under age 13 years.

Estimated numbers resulted from statistical adjustment that accounted for delays in reporting to the health department (but not for incomplete reporting) and missing risk factor information, where appropriate.

Cumulative totals include persons of unknown race/ethnicity. Because totals for the estimated numbers were calculated independently of the values for the subpopulations, the subpopulation values may not equal the totals.

AIDS Diagnoses by Age

Of the estimated number of AIDS diagnoses in the 50 states and the District of Columbia, the distribution of ages at time of diagnosis was as follows:

AIDS Diagnoses by Race/Ethnicity

CDC tracks AIDS information on seven racial and ethnic groups: American Indian/Alaska Native; Asian; Black/African American; Hispanic/Latino; Native Hawaiian/Other Pacific Islander; White and Multiple Races.

In 2009, the estimated number of AIDS diagnoses in the 50 states and the District of Columbia, by race or ethnicity was as follows:

AIDS Diagnoses by Transmission Category

Six common transmission categories are male-to-male sexual contact, injection drug use, male-to-male sexual contact and injection drug use, heterosexual contact, mother-to-child (perinatal) transmission, and other (includes blood transfusions and unknown cause).

Following is the distribution of the estimated number of AIDS diagnoses among adults and adolescents by transmission category in the 50 states and the District of Columbia. A breakdown by sex is provided where appropriate.

The distribution of the estimated number of AIDS diagnoses, among children* in the 50 states and the District of Columbia, by transmission categories was:

AIDS Diagnoses by Top 10 States/Dependent Areas

The 10 states or dependent areas reporting the highest number of AIDS diagnoses in 2009 were:

Persons Living With an AIDS Diagnosis

At the end of 2008, the estimated number of persons living with an AIDS diagnosis in the United States and dependent areas was 490,696. In the 50 states and the District of Columbia, this included 479,161 adults and adolescents, and 707 children under age 13 years at the end of the year.

Estimated numbers resulted from statistical adjustment that accounted for delays in reporting to the health department (but not for incomplete reporting) and missing risk factor information, where appropriate.

Because of delays in reporting of deaths, data are only available through the end of 2008. The exclusion of data from the most recent year allows at least 18 months for deaths to be reported and for these persons to be removed from calculations of persons living with an AIDS diagnosis.

Totals include persons of unknown race/ethnicity. Because totals for the estimated numbers were calculated independently of the values for the subpopulations, the subpopulation values may not equal the totals.

Deaths of Persons With an AIDS Diagnosis

In 2008, the estimated number of deaths of persons with an AIDS diagnosis in the United States and dependent areas was 16,605. In the 50 states and the District of Columbia, this included 16,084 adults and adolescents, and 4 children under age 13 years.

The cumulative estimated number of deaths of persons with an AIDS diagnosis in the United States and dependent areas, through 2008, was 617,025. In the 50 states and the District of Columbia, this included 589,547 adults and adolescents, and 4,949 children under age 13 years at death.

Deaths of persons with an AIDS diagnosis may be due to any cause.
