New population estimates show Dane County accounts for 35% of Wisconsin’s growth since 2020
DANE COUNTY – Dane County Executive Melissa Agard today highlighted new population estimates showing Dane County continues to lead Wisconsin in population growth, underscoring the strength of the region’s economy and the importance of planning for the needs of a growing community.
According to new data from the Wisconsin Department of Administration, Dane County’s population reached 621,365 residents as of January 1, 2026, an increase of nearly 60,000 people since the 2020 Census. That represents a 10.7% increase, making Dane County the fastest-growing county in Wisconsin in both total population gained and percentage growth.
Dane County accounted for approximately 35% of Wisconsin’s total population growth during that period, adding more than four times as many residents as Waukesha County, which ranked second in total population increase.
“People continue to choose Dane County because of the incredible quality of life, economic opportunities, and strong communities we have built together,” said County Executive Melissa Agard. “From our world-class educational institutions and growing businesses to our beautiful parks, vibrant communities, and strong public services, Dane County has so much to offer. This continued growth is a testament to the people, businesses, and organizations that make our county such a special place to call home.”
The new estimates, highlighted in a recent report from the Capital Area Regional Planning Commission, show that approximately 84% of Dane County’s population growth since 2020 has come from people moving into the county. Net migration has brought more than 50,000 additional residents to Dane County during that period.
The county’s continued growth also reinforces the importance of long-term planning. Regional projections suggest Dane County could approach 900,000 residents by 2050, creating significant demand for housing, transportation, infrastructure, and public services.
“As we welcome more people to Dane County, we have a responsibility to make sure our communities are prepared for the future,” Agard said.
“That means investing in affordable housing, maintaining strong infrastructure, supporting economic development, and protecting the natural resources that make Dane County such a desirable place to live. We want to ensure that as our county grows, the opportunities that bring people here continue to be available to everyone.”
Agard pointed to several ongoing county priorities that support responsible growth, including the proposed $20 million investment in the Affordable Housing Development Fund in the 2027 Executive Budget, continued investments in county roads and bridges, the redevelopment of the Alliant Energy Center campus, and improvements at the Dane County Regional Airport.
The county is also continuing its commitment to land conservation, farmland preservation, and water quality protection, recognizing the importance of balancing development with environmental stewardship.
“Dane County’s growth presents tremendous opportunities for our future,” Agard added. “By working together with our municipalities, businesses, and community partners, we can continue building a county where families can thrive, businesses can succeed, and future generations can enjoy the same exceptional quality of life that makes Dane County so special.”
The population estimates were released by the Wisconsin Department of Administration and highlighted in an October 15 report by the Capital Area Regional Planning Commission.
