Cedar Rapids is the second-most populous city in the U.S. state of Iowa and the county seat of Linn County. The city lies on both banks of the Cedar River, 20 miles (32 km) north of Iowa City and 128 miles (206 km) northeast of Des Moines, the state's capital. It is a part of the Cedar Rapids/Iowa City region of Eastern Iowa, which includes Linn, Benton, Cedar, Iowa, Jones, Johnson, and Washington counties. At the 2020 census, the city population was 137,710. The population of the three-county Cedar Rapids metropolitan area, which includes the nearby cities of Marion and Hiawatha, was 276,520 in 2020. Cedar Rapids is an economic hub of the state, located at the core of the Interstate 380 corridor. The Cedar Rapids metropolitan area is also a part of a combined statistical area with the Iowa City metropolitan area. Cedar Rapids is nicknamed the "City of Five Seasons", for the so-called "fifth season", which is time to enjoy the other four. This slogan is often satirized by residents as the "City of Five Smells", as a result of the smell combinations in the 1970s from the city's Quaker Oats and Penford factories, a hog slaughterhouse, and the municipal sewage plant and landfill. The symbol of the five seasons is the Tree of Five Seasons sculpture in downtown along the north river bank. The name "Five Seasons" and representations of the sculpture appear throughout the city in many forms. A flourishing center for arts and culture in Eastern Iowa, the city is home to the Cedar Rapids Museum of Art, the National Czech & Slovak Museum & Library, the Paramount Theatre, Orchestra Iowa, Theatre Cedar Rapids, the African American Museum of Iowa, and the Iowa Cultural Corridor Alliance. In the 1990s and 2000s, several Cedar Rapidians became well-known actors, including Ashton Kutcher, Elijah Wood, Terry Farrell, and Ron Livingston. The city is the setting for the musical The Pajama Game and the comedy film Cedar Rapids.
