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, and
other indicators of population change. DSC releases preliminary
population estimates by August 10, and final population estimates by
October 10, with a reference date of January 1 of the current year.
