Earth is home to more than 7.4 billion people. This is expected to increase in the coming decades to more than 9.7 billion. Some countries have initiatives to help control the population, but others are encouraging large families. There are 193 countries that are United Nations members, two that are officially recognized UN observers, and two unrecognized nations, in the world that people call home. Some of these, such as Vatican City, aren’t highly populated. Other countries are highly populated.
China is the most populated country in the world with an estimated 1.389 billion residents. This is expected to decline in coming decades due to the one-child policy that ended in 2016. The decades of limiting couples to one child means that by mid-century, there will be a decrease in the population. The Chinese Academy of Social Sciences notes that by 2065, the population will dip to 1.172 billion.
