BRFS: Which Module Should I Use?
To track BRFS estimates over time (from 2000 onward) or to get estimates for a single year, use the
State, Regions, and Selected Counties (Trend Data) module. This provides
estimates for the state of Wisconsin, DHS regions, and
selected counties for the years 2000 and later. This module includes only topics which
appeared in the survey every year since 2000.
To get BRFS estimates for all 72 counties in Wisconsin, or for counties not found in the Trend Data module, use the
All Counties module (2004-2006, 2005-2007 combined data).
Estimates for counties shown in both modules may differ because the weights used in the modules are different. Data in the Trend Data module
are weighted to provide results that represent
Wisconsin and the five DHS regions, while data in the All Counties module are weighted to provide results that
represent the population in each individual county.
Users seeking trend data or single-year data for these counties should use the Trend Data module. Users seeking
average estimates for 2004-2006 or 2005-2007 in these counties are advised to use the All Counties module.
