The estimates presented here are based on TUS/CPS data and an underlying model based on the demographic profile of each geographic area. When there is sufficient TUS/CPS data for a specific geographic area, the combined estimates depend mainly on the available data from that geographic area.
However, for areas with little or no TUS/CPS sample, the estimates increasingly depend on using the demographic model to produce estimates for areas with "similar" profiles from across the country in terms of their covariates. These latter estimates cannot capture unique characteristics of the county not represented by the demographic profile, and also cannot capture specific cancer control programs that may have been implemented to decrease smoking rates in that area.
Feedback is greatly appreciated, both in terms of the global utility of these estimates, as well as local anomalies.
