Lansing is the capital city of the U.S. state of Michigan, and the state's sixth largest city. It is located mostly in Ingham County, although small portions of the city extend into Eaton County. Lansing has a population of 119,128, an Urbanized Area (UA) population of 300,032, and, as of July 1, 2007, a Metropolitan Statistical Area (MSA) population of 456,440. The even larger Combined Statistical Area (CSA) population, which includes Shiawassee County, is estimated at 528,193
The Lansing metropolitan area, colloquially referred to as "Mid-Michigan," is an important center for educational, cultural, governmental, business, and high-tech manufacturing institutions, including three medical schools (two human medicine and one veterinary), two nursing schools, two law schools, a Big Ten Conference university (Michigan State), the state capital, the state Supreme Court and Court of Appeals, a federal court, the Library of Michigan and Historical Center, and headquarters of four national insurance companies. Lansing is the only U.S. state capital (among the 46 located in counties) that is not also a county seat. The county seat of Ingham County is Mason, Michigan, but the county maintains some offices in Lansing.
The city's public transportation is served by CATA (Capital Area Transportation Authority) via buses.
