If the E-BRFSS data to be provided to counties in March, 2009 contains only six months of data, how accurately will this information represent the risk profile of the county’s population?
While the sample will be representative of the adults in each county, the smaller size (n~325 for six months) of the sample means that the confidence intervals around the estimates will be larger (e.g., less precise). Also, estimates for population sub-groups will be unreliable because of limited sample size in these groups. Based on past analyses, we expect that estimates generated from the first six months will be comparable to the final estimates and that seasonality has a limited impact. Once the survey is completed, the preliminary estimates will be revised.
