More than 1.2 billion people live in China, making it the world's most populated nation.
China is about the same size as the United States, but is more than four times as crowded.
Seventy percent of China's people live on farms or in small villages. If you draw a line across China west from Shanghai, you can get an idea of how China's diverse climates affect where people live. The vast majority of China's people live south of Shanghai. In this part of China, people rather than machines do most of the work. Rice is the dominant crop, and rice farming requires more labor than other crops.
