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
Future challenges for China will be the gender disparity. According to the 2010 census, males account for 51.27% of China's 1.34 billion people, while females made up 48.73% of the total. The sex ratio (the number of males for each female in a population) at birth was 118.06 boys to every 100 girls (54.14%) in 2010, higher than the 116.86 (53.89%) of 2000, but 0.53 points lower than the ratio of 118.59 (54.25%) in 2005. In most western countries the sex ratio at birth is around 105 boys to 100 girls (51.22%). At the moment there are about 9 million more boys than girls in China.
