Question

The most populated country in the world is _______
a.China
b.India
c. the USA
d.Pakistan

Answer 1

Hint: The one-child policy has met with a great deal of opposition, especially in rural areas. Families who violate this strategy appear to cheat on census surveys, so the real population of this country might be a little biased.

Step by step answer:
 According to existing forecasts, China's population will eventually plateau in 2030, with a declining workforce and an economy of 240 million over 65.
Japan alone has aged more than in China. China has another very significant population crisis due to sex-selective abortion and its one-child scheme, resulting in a ratio of 120 boys per 100 children. It is predicted that by the end of the ‘30s, the percentage of men who have never married will quintuple by 2030, and the huge number of unmarried young people will have an adverse effect/impact on the Chinese population. India and China are projected to have 1.46 billion inhabitants each by 2026, but India will continue to take the first spot, with growth continuing until 2060, while China's population is predicted to decrease after 2030.
China’s Population Growth: China's demographic has long been a hot political problem. After a rapid population increase in the middle of the 20th century, the Chinese government tried to curb population growth by adopting the controversial "one-child strategy."
The one-child policy has met with a great deal of opposition, especially in rural areas. Families who violate this strategy appear to cheat on census surveys, so the real population of China might be a little biased. This means that Chinese demographic figures have been less accurate since the program started in the 1970s. The Chinese government terminated its program in 2016.

So, the correct option is

Note Most of China's economic development has been due to its plentiful and inexpensive labour force and low social costs. However, with the number of young Chinese decreasing and the number of elderly Chinese growing, it is doubtful if China's economy may continue to expand at the same rapid pace in accordance with its population growth shift.
