Explain briefly about the trends in population changes that affect the global economy

What will be an ideal response?

The population within the developed economies of the world is continuing to gray. It will impact medical markets, but not all opportunities will be in medicines. Older populations are living more active, healthier lives and will be a major market for goods and services across a broad spectrum of consumer products.
Hand in hand with aging populations, the birthrate in the high-income countries is collapsing. The combination of low birthrates and wealth will drive a continuation of the global economic migration of people from poor, undeveloped countries to the rich, developed countries. In the industrial world, college education and increased women in the workplace have reduced birthrates to the point where population is steady or declining.
