Introduction of topic

People's Republic of China (PRC), is the most populous country in the world, with over 1.3 billion citizens. Located in East Asia, the country covers approximately 9.6 million square kilometres (3.7 million square miles). It is the world's second-largest country by land area, and the third- or fourth-largest in total area, depending on the definition of total area

As recently as 1950, China's population was a mere 563 million. The population grew dramatically through the following decades to one billion in the early 1980s.China's total fertility rate is 1.7, which means that, on average, each woman gives birth to 1.7 children throughout her life. The necessary total fertility rate for a stable population is 2.1; nonetheless, China's population is expected to grow over the next few decades. This can be attributed to immigration and a decrease in infant mortality and a decrease in death rate as national health improves.
