2011-2013 COUNTY DATA

The data tabs below represent the most frequently requested data points for Wyoming BRFSS county-level data.  County data is aggregated over five years typically and is provided every two years.  Not all data points are able to be calculated at the county level due to small sample sizes or questions that are  asked only once during the aggregated time-frame.

If you need BRFSS data that is not listed listed below, please call Joe Grandpre at 307-777-8654 or email your request to joe.grandpre@wyo.gov

Note: Changes were made in how the BRFSS data was weighted and raked starting in 2011, great care should be taken in comparing data points prior to and after 2011.

Explanation of Tables

Explanation of Tables:

Selected results are now available from this website in the form of demographic tables. These tables include the prevalence estimates, and the 95% confidence intervals. The 95% confidence interval defines the margin of error for the prevalence estimate and is largely based on sample size. When the sample size is small for a particular demographic group, the corresponding margins of error are large and appropriate care should be taken when interpreting those results. When observing differences between two estimates for a particular indicator, confidence intervals which do not overlap will usually indicate a statistically significant difference.

Data that are not available are indicated by “—“. Percents and confidence intervals that are not reported due to inadequate sample size are also indicated by “—“.

County and race/ethnicity categories. On a annual basis, BRFSS cannot provide estimates by county or race/ethnicty due to the small size of many counties and some race/ethnicity groups. For those indicators that regularly appear on the questionnaire, 5 years of data are combined to produce estimates for every county and 5 race/ethnicity groups. These estimates are updated every 2 years.

Limitations of the data. Data are self-reported and subject to recall difficulties and misrepresentation. People excluded from the survey: those without telephones, those with only cell phones (through 2008), those living in nursing homes, prisons, other institutions, dormitories, other large group homes. Response rates for BRFSS and all telephone surveys have been declining in recent years making non-response bias a possible concern.

Inquiries. Further information about BRFSS can be obtained by contacting Joe Grandpre PhD., MPH, BRFSS Coordinator, Wyoming Department of Health, 6101 Yellowstone Road, Suite 510, Cheyenne, WY 82001, 307-777-8654, and at joe.grandpre@wyo.gov.
