Madison is the capital of the U.S. state of Wisconsin and the county seat of Dane County. It is also home to the University of Wisconsin?Madison. Its 2008 estimated population was 231,916 making it the second largest city in Wisconsin, after Milwaukee, and the 81st largest in the United States. Wisconsin state government and the University of Wisconsin?Madison remain the top two Madison employers. However, Madison's economy today is evolving from a government-based economy to a consumer services and high-tech base, particularly in the health, biotech and advertising sectors.
