Rock County Population Figures

Rock County’s current population of 159,372 (2017 estimate) continues to rank among Wisconsin’s largest counties. Steady-to-moderate population growth, as measured by comparative Census data, is directly attributed to the County’s close proximity to larger, metropolitan locations such as Madison, Milwaukee, Rockford and Chicago. Geography, industry and transportation linkages - coupled with lower cost of living indicators - continue to facilitate Rock County’s overall positive growth patterns.
