USA HIV & AIDS Statistics by Region and States

At the end of 2006, an estimated 448,871 people were living with AIDS in the USA. The highest numbers were in California, Florida, New York State and Texas. Among the 50 states, the lowest numbers were in North Dakota, South Dakota, Montana and Wyoming.

In 2006, the District of Columbia reported a far higher rate of AIDS diagnoses than any other area. Rates in New York State, Florida and Maryland were also much higher than the national average of 12.7 cases per 100,000 population per year.

In the 38 areas that have a history of confidential name-based HIV reporting, an estimated 233,079 people were living with HIV infection that had not progressed to AIDS. This number only includes people whose infection has been diagnosed and reported through the confidential name-based system.

According to the number of AIDS cases reported to the CDC, the 38 areas with a history of confidential name-based HIV reporting represent approximately 64% of the US epidemic. For this reason, and because many HIV infections remain undiagnosed (or anonymously diagnosed and unreported) within the 38 areas, the total number of people living with HIV (and not AIDS) in the USA must be much higher.

The CDC estimates that around one million people are living with HIV in the USA, including those not yet diagnosed, and including those who have already progressed to AIDS.

Notes

The latest statistics on AIDS & HIV in the USA were published in March 2008 by the US Centers for Disease Control and Prevention (CDC). The next data are due November 2008.

There is often a delay between the time of diagnosis of HIV or AIDS, or the time of death, and the time at which the event is reported. For this reason the CDC estimates the number of people living with HIV or AIDS by adjusting for reporting delays. No adjustment is made for incomplete reporting. On this page, all numbers are CDC estimates.

On this page "adults and adolescents" are defined as persons aged 13 years or more.

The term "living with AIDS" includes every living person who has ever received an AIDS diagnosis, regardless of their current state of health. The term "living with HIV (and not AIDS)" includes every living person who has been diagnosed with HIV through the confidential name-based system, but has never been diagnosed with AIDS.
