Community Health Survey

The New York City Community Health Survey (CHS) is an annual cross-sectional telephone survey conducted by the Bureau of Epidemiology Services at the New York City Department of Health and Mental Hygiene. The CHS provides data on the health of New York City residents. The annual sample includes approximately 8,500 adults ages 18 and older from all five city boroughs. All data collected are based on self-report.

The CHS data is used to provide measures of HIV testing and prevention in New York City. CHS participants are asked a) if they have ever been tested for HIV and b) if they have been tested for HIV in the past 12 months. For data regarding condom use, participants are also asked whether they used a condom the last time they had sex.

Notes on the HIV testing interactive visualization:
All estimates calculated based on the public use datasets.

Some data not shown (suppressed) on map and graphs due to estimates being imprecise:
a) relative standard error >= 50% with confidence interval band width >=6, or
b) relative standard error <30% and confidence interval half-width >10 or
c) estimates equal to 0% or 100% with a denominator <50.
Reliability: Sample sizes for some populations are quite small, making some CHS estimates potentially unreliable. The NYCDOHMH guidelines for data reliability incorporate relative standard error, confidence interval width, and sample size to identify potentially unreliable estimates.
Suppression:The estimate is suppressed if the denominator is less than 50 (n<50).

The New York State Department of Health (NYSDOH) AIDS Institute HIV Quality of Care (QOC) Program overseen by the Office of the Medical Director (OMD) is committed to promoting the quality of HIV clinical care and supportive services delivered to people with HIV in New York State (NYS) and to building capacity for quality management in HIV programs throughout the region. The QOC Program promotes improvement in HIV care, using a framework to achieve its objectives that includes the following components: performance measurement of clinical care and services, improvement coaching and consultation, exchange of improvement resources, peer learning, and collaborative participation of clinical experts and consumer representatives.

Performance measurement of HIV ambulatory care providers occurs through annual self‐reporting as part of the New York State HIV QOC Program review process. The HIVQUAL framework, developed by the NYSDOH AIDS Institute, is based on the concept that quality management programs should reflect a balance between quality improvement and performance measurement activities and be built on a sustainable programmatic infrastructure with active support from the agency’s leadership.

New York Links

NYLinks is a New York State Department of Health (NYS DOH), AIDS Institute initiative that focuses on improving linkage to care, retention in care, and viral load suppression to support the delivery of routine, timely, and effective care for Persons living with HIV/AIDS in New York State. HIV testing and care providers, supportive service groups and consumers participate in regional collaboratives (e.g. Upper Manhattan, Western NY, Hudson Region, Queens, Long Island) with an aim to improve linkage, retention and viral suppression across their region and the state. The NYLinks measures aim to monitor the progress and impact of the New York State collaborative efforts to improve linkage to and retention in HIV clinical care and viral load suppression.

All sites participating in NYLinks are encouraged to routinely collect the data and to report aggregate results through a web application every three months. The data should capture all patients/clients with a diagnosis of HIV/AIDS, regardless of age or funding source of services. These data are used to set regional priorities and evaluate the effectiveness of interventions developed.

NYLinks calculations for linkage, retention and viral suppression may differ from other NYS surveillance-based content. Definitions for NYLinks measures are footnoted on their respective data displays. You can find a description of the measures in detail here.


HIV/AIDS surveillance activities in New York are conducted by the Bureau of HIV/AIDS Epidemiology within the New York State Department of Health, and by the HIV Epidemiology & Field Services Program of the NYC Department of Health and Mental Hygiene. Both release annual detailed reports on the HIV/AIDS epidemiology within NYS and NYC.

Surveillance data includes information on new HIV/AIDS diagnoses (date, test and values, ordering provider), as well as all CD4 and VL laboratory test results following diagnosis that have been reported to the NYS Department of Health. From this information, we can use surveillance data to follow the number of new diagnoses and the number of persons living with HIV/AIDS in New York, as well as trends in linkage to care rates, retention in care rates, and viral load suppression data. Surveillance data can further assist in looking at this data by demographic or high-risk sub-populations. New York State and New York City are also funded by the Centers for Disease Control and Prevention (CDC) to assess incidence data, or estimated new HIV infections, using a method developed by CDC known as stratified extrapolation approach (SEA). Annual incidence estimates are an essential benchmark in tracking progress towards reducing new infections to 750 by the end of 2020.

As required by NYS Public Health Law, we follow the confidentiality standards set forth by both NYS DOH And NYC DOHMH when releasing aggregate data. For NYC surveillance: case counts of 1-5 person(s) with an underlying population denominator of ≤500 persons, or non-zero counts with a denominator ≤100 as per intercensal 2013 estimates are not shown.

Vital Statistics

The New York State Department of Health (DOH) collects data on live births and deaths recorded in New York State. Through a cooperative agreement, the New York State DOH receives data on live births and deaths recorded in New York City from the New York City Department of Health and Mental Hygiene and on live births and deaths recorded outside of New York State to residents of New York State from other states and Canada. Vital statistics data are used to provide a measure of AIDS mortality. The cause of death reported is based on the underlying cause and is classified according to the International Classification of Diseases.
