Enter a place (for example, "Beaufort County, SC") in the search box or double-click on an area of the map to zoom in. For example, to see detailed Beaufort County data, double-click on SC repeatedly until the county is visible, then double-click the county for even greater detail. Above a certain zoom level, the map will switch to census tracts.
Data options include census year (1990, 2000 and 2012 American Community Survey estimates). After choosing a data year, select a category using the measure dropdown menu. For most categories, you also can switch between a color-block view (choropleth) or bubbles.
