Between two thirds and three quarters of the population live in urban areas. Switzerland has gone from a largely rural country to an urban one in just 70 years. Since 1935 urban development has claimed as much of the Swiss landscape as it did during the previous 2,000 years. This urban sprawl does not only affect the plateau but also the Jura and the Alpine foothills and there are growing concerns about land use. However, from the beginning of the 21st century, the population growth in urban areas is higher than in the countryside.
