Question

Why China have largest population and why Vatican City have lowest population?​

Answer 1

Answer:

Overpopulation in China began after World War II in 1949, when Chinese families were encouraged to have as many children as possible in hopes of bringing more money to the country, building a better army, and producing more food.

Vatican City is the smallest country in the world, measuring just 0.2 square miles, almost 120 times smaller than the island of Manhattan. In comparing countries by population, however, Vatican City loses out to the Pitcairn Islands for the title of smallest country.
