Rock County, Wisconsin
This report explores how Rock County's community is changing and what makes it unique compared to the United States as a whole. Civic data about Rock County's residents, households, and housing is from the American Community Survey (ACS), conducted by the U.S. Census Bureau. Unlike the Census—which is an exact count of people and households every ten years—ACS statistics are estimated based on a representative survey sample of Rock County residents. The data is shown over five-year periods, rather than annually, to ensure greater accuracy at small geographies.
Age Demographics in Rock County, Wisconsin
Race and Ethnicity in Rock County, Wisconsin
The ACS adheres to definitions of race and ethnicity set forth by the 1997 Office of Management and Budget (OMB) standards. These categories are based on self-identification and are "not an attempt to define race biologically, anthropologically, or genetically," according to the Census Bureau.
According to the OMB standards, the category of "Hispanic" maps to the concept of ethnicity, not race, and so Rock County's percentage is not included in the race distribution chart above. A Rock County resident who identifies as Hispanic may be of any race or combination of races.
Educational Attainment in Rock County, Wisconsin
