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.
One-child policy
During the period of Mao Zedong's leadership in China, the birth rate fell from 37 per thousand to 20 per thousand. Infant mortality declined from 227 per thousand births in 1949 to 53 per thousand in 1981, and life expectancy dramatically increased from around 35 years in 1948 to 66 years in 1976. Until the 1960s, the government encouraged families to have as many children as possible because of Mao's belief that population growth empowered the country, preventing the emergence of family planning programs earlier in China's development. The population grew from around 540million in 1949 to 940million in 1976. Beginning in 1970, citizens were encouraged to marry at later ages and have only two children.
