Blue tones represent buildings and pavement, while red tones indicate natural and agricultural vegetation. In the 1970s, many people who spent the Cultural Revolution in the countryside returned to Beijing, and others came seeking jobs. 1979 brought a boom in housing construction. In the 1980s, many industrial plants were moved from the central city to outlying areas, and it became more common to live and work in different places. Beijing's 2012 population is estimated at just over 17 million, with a population density of about 5,000 people per square kilometer (about 13,000 people per square mile). Images taken by Landsat 2 and 5. Source: Earthshots: Satellite Images of Environmental Change, U.S. Geological Survey.
