The figures are model-based estimates for the adults of an area. They are not measurements. They say nothing about one person.

We do not produce estimates for individuals; only aggregated results for counties, places, census tracts, or ZCTAs.

First, it is not adequate to simply compare point estimates. The confidence intervals should also be considered, and some are very broad.

The dashed line in each drawing is the South Dakota figure. It is a mean of the county estimates, weighted by the number of adults (site aggregate). It has no interval, so the words are "above", "below" and "in line". The table is in name order. The intervals of many rows overlap, so the table gives no rank.

State figures: 40 measures by CDC category

Crude prevalence is the estimated share of all adults. Age-adjusted prevalence uses the 2000 US standard population, so that areas with different ages can be compared. CDC: Age-adjusted estimates are only available at the county and place-level.

A state figure is a mean of the county estimates, weighted by the number of adults (site aggregate). It has no interval. The words say if the figure is above, below or within the 95% confidence interval of the US estimate.

The boundaries and the links between ZIP Codes, counties and places come from the US Census Bureau. Percentages have one decimal, as CDC publishes them. A state figure is a site aggregate: the site computes it. The site multiplies the estimate of each county by its number of adults. It adds the products and divides the sum by the number of adults in South Dakota. CDC gives this method for a group of areas. Some measures are about a part of the adults, for example women aged 50 to 74. For them the weight is all adults, which is an approximation.
