WISH Query
Behavioral Risk Factor Survey
Trend Data: State, Regions, Counties

(Revised November 2011)

This module offers state and sub-state level estimates from the Behavioral Risk Factor Survey (BRFS), which uses a representative sample of Wisconsin adults living in households with landline telephones. The BRFS Trend Data Module includes only topics that have appeared in the survey since 2000. BRFS data are weighted to represent the state's adult population (see Technical Notes).

This Trend Data module provides BRFS estimates by county, with some restrictions based on the number of interviews. The All Counties Module also provides estimates by county for specific three-year periods.

The Wisconsin Behavioral Risk Factor Survey is part of the national Behavioral Risk Factor Surveillance System (exit DHS), which is coordinated by the U.S. Centers for Disease Control and Prevention (CDC). Every state and U.S. territory health department conducts the survey as part of the system, whose purpose is to collect information on adult health-risking behaviors, health conditions, use of preventive care and other health-related topics.

To define your query, choose a topic (BRFS definitions) from the list in Step 1. This will be the row variable in your table. Step 2 lets you decide whether to see standard results (percents) or age-adjusted results. Define a column variable for the table in Step 3 by selecting either years, geographic areas, a respondent characteristic or a second survey measure.

If desired, use Steps 4-6 to further refine your request. Select one or more available data years in Step 4. Step 5 lets you produce results for Wisconsin statewide; DHS regions; selected counties; or the City of Milwaukee and the balance of Milwaukee County. Step 6 lets you focus results on subgroups of respondents. Please note, it is strongly recommended that you combine two or more years of data for analysis by subgroups to increase the reliability of estimates.

Results will be reported only when at least 100 interviews have been completed on the selected item.

Step 2. Choose measure


Step 3. Choose a Column Variable

Respondent characteristics

 Another survey measure


Step 4. Choose Survey Years (default is most recent year)

Note to users who want to estimate population numbers for a condition or risk factor: If results are based on more than one year of data, divide the "Estimated Number in Population" by the number of years. This will produce an average population estimate for the time period. (See Technical Notes.)

Step 5. Choose One or More Geographic Areas

Wisconsin: (default)
