them. The town is staged and is busy readying itself to becoming open to the public. Poland Widzew, a suburb of Łódź in Poland, had been a textile company town before the Second World War. Slovakia Svit in Slovakia was founded in 1934 by business industrialist Jan Antonín Baťa in accordance with his policy of establishing well-organized model communities for his workers and other employees. This town (like other Baťa's company towns) was also an example of social engineering. Sweden The mining city of Kiruna in Sweden was originally, around 1900, built by the mining company in an unpopulated area. Many buildings, including the church, were built by the company. There are also many smaller towns that were built and even planned by companies. Skoghall in Värmland is such an example where Stora AB owned a papermill and contained a city-planning office. Ukraine The city of Pripyat in Ukraine was established in 1970 solely to house the workers at the adjacent Chernobyl Nuclear Power Plant and their families. It was one of several "nuclear cities" constructed by Soviet nuclear power firms throughout the latter half of the 20th century. All amenities, stores, and employment was conducted through each nuclear city's power plant administration. United States At their peak there were more than 2,500 company towns, housing 3% of the US population. The companies that ran the towns were primarily labor companies such as coal, steel, lumber and various war industries. Most of the people living in these towns were immigrants new to the country. Companies exerting a tight, paternalistic control over the residents' behaviour and even opinions caused issues and concern. Segundo, Colorado, was a company town where the CF&I coal company housed its workers. It offered adequate housing and promoted upward mobility through its sponsorship of a YMCA Center, an elementary school, and some small businesses, as well as a company store. However, air pollution was a constant health threat, and the houses lacked indoor plumbing. As demand for metallurgical coal declined, the mine laid off workers, and Segundo's population declined. After a major fire in 1929, CF&I left town, and Segundo became practically a ghost town. One famous company town was McDonald, Ohio, which was created by the Carnegie Steel Company to house and serve the needs of its employees in the Youngstown, Ohio, area. Marktown, Clayton Mark's planned worker community, was an example in northwest Indiana. In
