How does fertility affect population?

The global average fertility rate is just below 2.5 children per woman today.

What is the difference between fertility rate and birth rate?

Birth rate is a parameter of the entire population, while fertility rate is a parameter of a group of individuals in the population. Fertility rate determines the birth rate but, not the other way around. Fertility rate applies for females in the reproductive age, but there is no such restriction for birth rate.

What causes population momentum?

Population momentum is typically caused by a shift in the country's demographic transition. When mortality rates drop, the young survive childhood and the aging population live longer. Fertility rates remain high, causing the overall population size to grow.

What is a country's fertility rate?

The fertility rate of a country is a figure that reflects the number of children a woman would give birth to under two conditions: the woman was to experience age-specific fertility rates and if the woman were to survive through her reproductive childbearing years.

How does mortality rate affect population growth?

Population change is governed by the balance between birth rates and death rates. If the birth rate stays the same and the death rate decreases, then population numbers will grow. If the birth rate increases and the death rate stays the same, then population will also grow.

What is population explain?
