China is home to roughly 1.4 billion people, which is around 20 percent of the world's total population
The government of China officially espouses state atheism. Confucianism and Taoism (Daoism), later joined by Buddhism, constitute the "three teachings" that have shaped Chinese culture. There are no clear boundaries between these intertwined religious systems, which do not claim to be exclusive, and elements of each enrich popular or folk religion.
One of the unintended side effects of the one-child policy is that China is now the most gender-imbalanced country in the world due to a cultural preference for male offspring. This has resulted in the practice of couples opting to abort female fetuses. Abortion is legal in China, although sex-selective abortion is not.
The gender ratio in China is 117.6 boys for every 100 girls born. Some researchers estimate that there will be approximately 30 million more young men than women in China by 2020. This means millions of Chinese men may not be able to find wives.
