Factors influencing birth rate and fertility rate?
Birth Rate: The birth rate of a society refers to the number of births per 1,000 people in that society. This figure is expressed as the crude birth rate (CBR) and is calculated without consideration of the sex or age of the population. Death Rate: The death rate of a society is figured in the same manner but with regard to deaths rather than births and is expressed as the crude death rate (CDR). Fertility Rate: The fertility rate of a society is the average number of children which would be born by a woman during her "childbearing" years. Replacement fertility is the fertility level at which women on the average are birthing just enough children to "replace" themselves and their partners in the population.

What is the birth rate?
For this question, the CIA World Factbook will be used. According to a 2009 estimate, the number of the "birth rate in the world" shows to be 19.86/1,000 population. This is the crude birth rate: the average number of births a year during a year per 1,000 person in the population at midyear. The crude birth rate is used to indicate fertility, but keep in mind that it is affected by age, unlike the total fertility rate. The total fertility rate is 2.5 and measures the number of children that a woman has over the course of her life; it is synonymous to the crude birth rate in that is is a another way to measure birth rate.
