USA HISTORY

Detailed explanation-1: -Population growth accompanies changes in fertility rates due to better education about birth control. According to the World Bank, the aging population and low fertility rates are to blame for the increase in population as 36 percent of the world’s population over 65 currently live in East Asia.

Detailed explanation-2: -Overall, population grows or shrinks through two very basic components – natural change (births minus deaths) and migration (domestic plus international).

Detailed explanation-3: -When demographers attempt to forecast changes in the size of a population, they typically focus on four main factors: fertility rates, mortality rates (life expectancy), the initial age profile of the population (whether it is relatively old or relatively young to begin with) and migration.

Detailed explanation-4: -Population growth in Asia was close to 0.55% p.a. as of 2022, with highly disparate rates. Many Western Asian countries have growth rates above world average, notably Pakistan at 2% p.a., while China had a small decrease of 850, 000 habitants and India had a 0.6% increase in 2022.
