Land use in China
China has four times the population of the U.S., within roughly the same area. With 1.3 billion inhabitants, 20% of the world’s population lives in China. While the rate of population growth has been declining for decades, the total number of inhabitants has been growing and is expected to do so through 2030. China’s urban population is growing rapidly; between 1950 and 2009, the percentage of the population living in urban areas quadrupled from 14% to 48%. Meanwhile, the rural population is declining, opening the landscape in areas that are not urbanized. The forests and farming land of eastern China support far more people and major cities than do the grasslands, deserts, and high mountain regions of the west.
Demographics of China
China now has an increasingly aging population; it is projected that 11.8% of the population in 2020 will be 65 years of age and older. Health care has improved dramatically in China since 1949. Major diseases such as cholera, typhoid, and scarlet fever have been brought under control. Life expectancy has more than doubled, and infant mortality has dropped significantly. On the negative side, the incidence of cancer, cerebrovascular disease, and heart disease has increased to the extent that these have become the leading causes of death. Economic reforms initiated in the late 1970s fundamentally altered methods of providing health care; the collective medical care system has been gradually replaced by a more individual-oriented approach.
