Sioux Falls is a city with a high quality of life. With the Washington pavilion, the Sioux Falls park, the Zoo and many sports facilities the city has attractive possibilities for leisure-time activities and recreation. With the House of Butterflies opening its doors to the public just a few months ago another sight has been added to the city's must-see attractions. Two hospitals ensure top medical care. Excellent possibilities for education and training exist at public and private schools, at the Augustana College, at the University of Sioux Falls and at the branch campuses of the Dakota State Universities, the University of South Dakota and South Dakota State University. Sioux Falls is the centre of trade, banking and companies in the service industries but also the cultural centre for the whole region. Of major importance is the EROS DATA Center, a scientific institution run by the US government which makes basic cartographic information available by the provision of satellite imaging photographs. There are modern high-tech companies but also enterprises working in the field of agriculture – they produce agricultural machines and equipment and others firms work in the processing of the agricultural products of the region. Statistics show an unemployment rate of only 2.9 percent. It is an interesting fact that the number of the city’s inhabitants increases each and every year by about 3,000. Currently the friendly city in the midwest of the USA has 131,000 inhabitants who live in an area of 58.3 square miles.
