Statistics Overview

Unless otherwise noted, the following data are from CDC’s HIV Surveillance Report: Diagnoses of HIV Infection in the United States and Dependent Areas, 2014; vol. 26.

Definitions

  • Diagnosis of HIV infection: The term refers to persons diagnosed with HIV infection, regardless of the stage of disease at diagnosis (i.e., HIV infection Stage 1, 2, 3 [AIDS], or unknown), from 50 states, the District of Columbia, and 6 U.S. dependent areas.
  • HIV infection, stage 3 (AIDS):The term refers specifically to persons with diagnosed HIV whose infection was ever classified as stage 3 (AIDS), based on CDC’s 2008 revised surveillance case definitions for adults, adolescents, and children.
  • 6 U.S. dependent areas included in the data: American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, the Republic of Palau, and the U.S. Virgin Islands.
  • Transmission category: The term for summarizing the multiple risk factors that a person may have had by selecting the one most likely to have resulted in HIV transmission. For surveillance purposes, persons with more than one reported risk factor for HIV infection are classified in the transmission category listed first in a hierarchy of transmission categories, and therefore counted only once. The exception is men who had sexual contact with other men and injected drugs; this group makes up a separate transmission category.
  • HIV prevalence: The number of persons living with HIV at a given time regardless of the time of infection, whether the person has received a diagnosis (aware of infection), or the stage of HIV disease.

For more definitions and details about how HIV infection and AIDS data are tabulated, read the "Technical Notes" from the HIV Surveillance Report: Diagnoses of HIV Infection in the United States and Dependent Areas, 2014.

HIV Prevalence Estimate

Prevalence is the number of people living with HIV infection at a given time, such as at the end of a given year.

At the end of 2012, an estimated 1.2 million persons aged 13 and older were living with HIV infection in the United States, including 156,300 (12.8%) persons whose infections had not been diagnosed.a

Diagnoses of HIV Infection, by Race/Ethnicity

CDC tracks diagnoses of HIV infection among 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 2014, the estimated number of diagnoses of HIV infection in the United States was as follows:

aHispanics/Latinos can be of any race.

For more details on HIV infection and race/ethnicity, see CDC's Populations and Surveillance fact sheets.

Diagnoses of HIV Infection, by Transmission Category

CDC classifies HIV diagnoses into six transmission categories to which transmission may be attributed: 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 diagnoses of HIV infection in 2014 among adults and adolescents in the United States, by transmission category. A breakdown by sex is provided, where appropriate.

Estimated Number of Diagnoses of HIV Infection, 2014
Transmission Category Adult and Adolescent Males Adult and Adolescent Females Total

Persons Living With a Diagnosed HIV Infection

At the end of 2012, there were an estimated 914,826 persons living with diagnosed HIV infection in the United States.

Data include persons with a diagnosis of HIV infection regardless of the stage of disease at diagnosis. Estimated numbers resulted from statistical adjustment that accounted for delays in reporting to the health department (but not for incomplete reporting) and missing transmission category, where appropriate.

Because of delays in reporting of deaths, death and prevalence data are only available through the end of 2012. 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 diagnosed HIV infection.

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 these totals.

Stage 3 (AIDS)

The estimated number of persons in the United States whose diagnosed HIV infection was classified as stage 3 (AIDS) in 2014 was 20,896. Of these, 15,624 stage 3 (AIDS) classifications were among adult and adolescent males, 5,168 were among adult and adolescent females, and 104 were among children younger than 13.

The cumulative estimated number of persons in the United States with diagnosed HIV infection ever classified as stage 3 (AIDS) at year-end 2014 was 1,210,835.

Estimated numbers resulted from statistical adjustment that accounted for delays in reporting to the health department (but not for incomplete reporting) and missing transmission category, 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 these totals.

Stage 3 (AIDS), by Age

In 2014, the estimated number of stage 3 (AIDS) classifications in the United States, by age at time of classification, was as follows:

Age (Years) Estimated Number of Persons with Diagnosed HIV Whose Infection Was Classified as Stage 3 (AIDS) during 2014

Stage 3 (AIDS), by Transmission Category

CDC classifies HIV and stage 3 (AIDS) data into six transmission categories, to which infection may be attributed: 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 persons in the United States with diagnosed HIV whose infection was classified as stage 3 (AIDS) in 2014, by transmission category. A breakdown by sex is provided where appropriate.

Persons Living With Diagnosed HIV Infection Ever Classified as Stage 3 (AIDS)

At the end of 2013, an estimated 516,401 persons in the United States were living with diagnosed HIV infection ever classified as stage 3 (AIDS). Estimated numbers resulted from statistical adjustment that accounted for delays in reporting to the health department (but not for incomplete reporting) and missing transmission category.

Because of delays in reporting of deaths, prevalence data are only available through the end of 2013. 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 these totals.

Deaths of Persons With Diagnosed HIV Infection Ever Classified as Stage 3 (AIDS)

In 2013, the estimated number of deaths of persons with diagnosed HIV infection ever classified as stage 3 (AIDS) in the United States was 12,963.

The cumulative estimated number of deaths of persons with diagnosed HIV infection ever classified as stage 3 (AIDS) in the United States, through 2013, was 673,538.

Deaths of persons with diagnosed HIV infection ever classified as stage 3 (AIDS) may be due to any cause.

Estimated numbers resulted from statistical adjustment that accounted for delays in reporting to the health department (but not for incomplete reporting) and missing transmission category, where appropriate. Because of delays in reporting of deaths, data are only available through the end of 2013. The exclusion of data from the most recent year allows at least 18 months for deaths of persons with an AIDS diagnosis to be reported.

International Statistics

HIV disease continues to be a serious health issue for parts of the world. Worldwide, there were about 2 million new cases of HIV in 2014. About 36.9 million people are living with HIV around the world. An estimated 1.2 million people died from AIDS-related illnesses in 2014. Since 2000, around 25.3 million people have died of AIDS-related illnesses. Sub-Saharan Africa, which bears the heaviest burden of HIV/AIDS worldwide, accounts for 66% of all new HIV infections. Other regions significantly affected by HIV/AIDS include Asia and the Pacific, Latin America and the Caribbean, and Eastern Europe and Central Asia. CDC's Global AIDS website explains what CDC is doing in countries where HIV and AIDS have had great impact.
