The Demographic Services Center annually produces population estimates for Wisconsin counties and municipalities.
The estimates are based on the prior census and analysis of
contemporary data including housing units, dormitory and institutional
populations, automobile registrations, residential electric meters and
other indicators of population change. DSC releases preliminary
population estimates on August 10, and final population estimates on
October 10, with a reference date of January 1 of the current year.
