NCHHSTP Epidemiologic and Economic
Modeling Agreement (NEEMA)
NEEMA is a 5-year cooperative agreement funded by CDC/NCHHSTP to
further modeling efforts in five areas:
•
•
•
HIV
Tuberculosis
Sexually Transmitted Diseases
•
•
Viral Hepatitis
School/Adolescent Health
NEEMA’s purpose is to create and adapt models to support public health
decision-making and effectiveness at national, state and local levels.
This work was supported by the CDC/NCHHSTP Epidemiologic and Economic Modeling Agreement
(5U38PS004646). The findings and conclusions are solely the responsibility of the authors and do
not necessarily represent the official views of the Centers for Disease Control and Prevention or
the Department of Health and Human Services.

Emory Coalition for Applied
Modeling for Prevention (CAMP)
The Emory Coalition for Applied Modeling for Prevention (CAMP) is the Emory
University-coordinated workgroup funded by NEEMA.
CAMP was developed
as a collaboration
between CDC
scientists, academic
researchers, and public
health providers from
institutions across the
United States to create,
refine, and disseminate
models to improve
public health practice.

Methods Overview
• The detailed methodology was published in 2016:
Grey JA, Bernstein KT, Sullivan PS, Purcell DW, Chesson HW, Gift TL, Rosenberg ES. Estimating the population
sizes of men who have sex with men in US states and counties using data from the American Community
Survey. JMIR Public Health Surveill 2016;2(1):e14. DOI: 10.2196/publichealth.5365
• The method uses data from 5-year ACS summary files:
• Number of adult males
• Number of households
• Number of male-male households (male householder and male partner)
• It also incorporates estimates from published analysesa,b:
• Percentage of US men who have had sex with another man in the past 5 years (3.9%)a
• Percentage of US men who have had sex with another man in the past year within four
urban-rural categoriesb
•
•
•
•
Central counties of large metropolitan areas (4.4%)
Fringe counties of large metropolitan areas (2.5%)
Counties in medium or small metropolitan areas (1.4%)
Counties that are not in metropolitan areas (1.1%)

United States
Using the estimates, Emory CAMP
created maps showing:
• Number of MSM by US state
• Percentage of MSM among adult men by
US state
United States Highlights (2013)
• Estimated men who had sex with men (MSM) in
the past 5 years: 4,503,084
• Largest state population of MSM: California,
792,750 (17.6% of all MSM in the United States)
• Number of MSM by US county
• Highest percentage of MSM among adult men
in a state: Rhode Island, 6.0%
• Percentage of MSM among adult men by
US county
• Percentage of MSM among adult men in the
District of Columbia: 15.3%
• Percentage of US MSM residing in central or
fringe counties of large metropolitan areas:
>75%

Caveats & Limitations of Maps
• The statistics and maps reflect indirect estimates based on same-sex
households, male population sizes, and behavioral findings from peerreviewed publications. Behavioral data were not collected directly.
• The data used to construct the estimates are from pooled, five-year
American Community Survey (ACS) summary files. Therefore, they reflect
data collected over a period of time.
• Map users should exercise caution when interpreting data from areas with
few estimated MSM (e.g., <100) and with sparse populations in general.
