CAUTION: County boundaries have changed over time; if you are creating statistics on population density, don't mix apples and oranges. New counties were carved out of the acreage of existing counties until Dickenson County was finally created in 1880. Since then, annexations and mergers of cities and counties have also changed the political boundaries.
