BRFSS Maps is an Internet-based Behavioral Risk Factor Surveillance
System (BRFSS) mapping application that allows users to map BRFSS data interactively
for state and metropolitan/micropolitan statistical areas (MMSAs). Beginning
with 2002 BRFSS data, visitors to the BRFSS website can create, save, and
print state- and MMSA-level maps for health-related risk factors.
State and MMSA data can be displayed independently or in combination
to facilitate exploratory data analysis of within-state variations and identification
of regional patterns. Users can choose from several advanced map display options,
including number of data classes (i.e., two through six), data classification
method (e.g., equal interval, natural breaks, quantile, and standard deviations),
state and MMSA labels, and the option to display or hide outlying states and
territories. Standard map interface tools are provided to enhance users’
abilities to interact with the map, including zoom (via tool or drop-down
menus), pan, rate retrieval, map recenter, and map reset. Users also can download
state and MMSA BRFSS data in a geographic information system (GIS) shapefile
format for in-depth analysis in a GIS.
BRFSS Maps is available at http://apps.nccd.cdc.gov/gisbrfss.
Plans are under way for additional enhancements to BRFSS Maps, including advanced
exploratory data analysis tools, data histograms, multivariate mapping capabilities,
county-level mapping, and trend maps. Additional information is available
