The Department of Health Services, Office of Health Informatics, produces mid-year population estimates for the counties and state of Wisconsin by age and sex categories for non-Census years. Estimates are used to calculate population-based health statistics. (Estimates for age and sex categories may not sum to totals shown due to rounding.)
Population data for Wisconsin are also available through a data query system.
