What is Fertility?

The Penguin Dictionary of Human Geography states that

Fertility is a terms which refers in general context to all aspects of human reproduction leading to live births, but in a narrow sense to the achieved number of live births.

Global Trends

The United Nations is a key observer in global population trends and it has a few agencies that monitor different aspects of the population. The main agency is the United Nations Fund for Population Activities (UNFPA).

Fertility Rate is the number of children born to women of child-bearing age.

Birth Rates, Total Fertility Rates and Replacement Rates

Crude Birth Rate is the number of babies born per 1,000 population

Total Fertility Rate (TFR) is the number of children a woman is expected to have during her lifetime, based on the current birth rates. The present world average is 3.1. The TFR is one of the best indicators of population growth.

In 1998 the UN stated that 2.1 was the TFR needed by a country to replace its population. The Replacement Rate is when there are just enough children born to balance the number of people who die.

•Higher levels of family planning use are associated with lower levels of childbearing. •In Africa, where a small proportion of married women of childbearing age practice family planning (26 percent), on average women have more than five children each.•In contrast, in more developed regions, where a much greater percentage of married women of childbearing age practice family planning (68 percent), women have fewer children (under two on average).
