TFR

Today in human geography class, we talked about total fertility rate(TFR). It is the average number of children to born per woman. For a population to increase,the TFR would need to be 2.1 or higher. If the TFR is lower then 2.1 the population will decrease. The world TFR is currently 2.42, however, last year it was 2.47. This means the population in decreasing. This is because factors like birth control is becoming more available to different parts of the world. Nigeria is a developing nation, the TFR is 6.89. However, even though this is such a high rate, AIDS is very prevalent in this area which kills many children. The United States TFR is 2.01, which is supposed to mean the population is dropping by a good amount, however, due to immigrants from other countries the rate at which the population is decreasing is changed. Japan's TFR is 1.40, which is way below 2.1. The population is decreasing a lot.
