What will happen to population size if the birth rate and death are equal?

If the birth rate and death rate are equal, the population size will remain stable. This is because the number of people being born is equal to the number of people dying, so the total population size does not change. This situation is also known as a zero population growth rate (ZPG).

ZPG can occur for a variety of reasons, such as when a country has a low birth rate and a low death rate, or when a country has a high birth rate and a high death rate. In either case, the population size will remain the same.

ZPG can have a number of positive and negative impacts on a country. On the positive side, ZPG can help to reduce environmental pollution and resource depletion, as well as improve the quality of life for citizens. On the negative side, ZPG can lead to an aging population, which can put a strain on the economy and social services.

Whether ZPG is a good or bad thing is a matter of debate. Some people believe that ZPG is necessary to ensure the sustainability of the planet, while others believe that it is a sign of economic stagnation. Ultimately, the decision of whether or not to pursue ZPG is a complex one that must be made on a case-by-case basis.
