PHILADELPHIA
HIV/AIDS statistics for Philadelphia are collected by the AIDS Activities Coordinating Office (AACO). AACO’s statistics page contains:
- Graphs and maps of demographic trends
- Instructions and contact information for specialized data requests

PENNSYLVANIA
For Pennsylvania statistics, including statewide reports, regional reports, and specialized data requests, see the PA Department of Health HIV/AIDS Annual Summary & Other Reports and its Integrated Epidemiologic Profile of HIV/AIDS in Pennsylvania.
For more Pennsylvania statistics (with a particular emphasis on HIV/AIDS funding), see the Kaiser Family Foundation’s State Health Facts webpage on PA and HIV. The State Health Facts page also allows you to compare PA to other states and to find information on other health issues.
NATIONAL
For US-wide statistics, see the U.S. Center for Disease Control and Prevention (CDC) website on HIV/AIDS Statistics and Surveillance.
You can also make data requests from the CDC, at their Contact CDC page.
For historical study of the epidemic, see Past Issues back to 1982 of the CDC Surveillance Report.
The Kaiser Family Foundation also has lots of good statistical analysis at their HIV/AIDS in the US webpage. There isn’t one single statistics page, but if you use their “sort” tool, at the bottom of the page, you can sort by Document Type: Charts & Data and Subtopic: HIV/AIDS in the US.
GLOBAL
The Joint United Nations Programme on HIV/AIDS, UNAIDS, has a webpage on HIV Data with:
- Its most recent report, 2008 Report on the Global AIDS Epidemic (Almost all statistical accounts of the worldwide epidemic use this report for their raw data)
- The most recent AIDS Epidemic Update (which explores new findings and trends)
- Fact sheets on The Epidemic by Country
The World Health Organization (WHO) has a page of Data and Statistics. Be aware that many reports and data sets here are identical to those of UNAIDS linked above, as WHO is a co-sponsor of UNAIDS.
The U.S. Census Bureau has its own webpage of Global HIV/AIDS Surveillance. This includes a link to the Census Bureau’s HIV/AIDS Surveillance Database, which includes maps, summary tables, and the option to generate custom reports.
The University of California, San Francisco’s HIV InSite has a page on the epidemic by Counties and Regions. The basic data is drawn from the UNAIDS report linked above, but each page is also filled with links to reports, organizations, and other resources on that county or region.
HIV/AIDS Statistics by Population and by Risk Behavior
For U.S. statistics by age, race, and transmission category, see the Center for Disease Control and Prevention (CDC) webpage on Basic Statistics.
For more detailed reports on different populations and risk behaviors, see the CDC’s Surveillance Factsheets.
For statistics on HIV/AIDS disparities among different populations, see the Office of Minority Health & Health Disparities webpage, Eliminate Disparities in HIV and AIDS.
For collections of resources on 22 different populations, many with statistical information, see HIV Insite’s Population Links.
For a collection of reports on youth, see the CDC’s webpage on Healthy Youth: Sexual Risk Behaviors.
For populations worldwide, see the Joint United Nations Programme on HIV/AIDS’s webpage on Key Populations.
Information About HIV/AIDS Statistics
For definitions of HIV/AIDS terms and abbreviations, see the U.S. Department of Health and Human Services AIDSinfo Glossary.
For assistance reading and getting the most out of HIV/AIDS statistics, the U.S. Center for Disease Control and Prevention (CDC) has webpages on:
- The basics of HIV/AIDS Surveillance
- Technical Notes on surveillance
- Explaining the 15% Increase in HIV Diagnoses from 2004-2007
The Kaiser Family Foundation has some resources for better understanding HIV/AIDS statistics:
- A narrated slideshow on Understanding HIV/AIDS Surveillance Data in the United States
- A report on Understanding the New UNAIDS Estimates
- A narrated slideshow on The HIV/AIDS Epidemic in the United States (an introductory survey with a strong emphasis on statistics)
People sometimes have statistical questions about how likely it is to become infected with HIV from a certain behavior. Columbia University’s Go Ask Alice! Service has a webpage, Confused About HIV Transmission Statistics that helps explain why these statistics can’t be precisely calculated.
