2.1 is generally regarded as the replacement rate (the rate at which a population neither
grows nor shrinks) in the developed world. In less developed countries this rate should be higher to account for so many children not
reaching childbearing age.

Total Fertility Rate - the average number of children a women will
have in her childbearing years. This rate varies from just over 1 (Japan, Italy) to around 7 (Niger, Mali). The
U.S. rate is 2.

Infant Mortality Rate – the number of deaths of children under the age of one per thousand live births. The rate ranges from as low as 3 (Singapore,
Iceland) to as much as 150 (Sierra Leone, Afghanistan). The U.S. rate is just over 6. High infant mortality tends to result in higher fertility rates as families
seek “insurance” for the loss of children.
