aEach population estimate is calculated by multiplying the prevalence estimate for that geographic area (from analysis of data from the National Health and Nutrition Examination Survey) by the total population size for that geographic area (as determined from census data) and is rounded to the nearest thousand. Because the prevalence estimates are rounded, the individual estimates may not sum to the overall number or to 100 %
bCounties assigned to urbanicity levels in accordance with 2006 NCHS urban-rural classification scheme. Due to missing data, urbanicity levels do not sum to overall number
cStates assigned to regions in accordance with US Census Bureau determinations
