Fertility refers to the actual reproductive performance whether applied to an individual or group. Total fertility rate is a term used as the sum total of age specific fertility rates. The total fertility rate specifies the number of children a woman would have as she passes through child bearing span. Each marriage increase the likelihood of more children as women in the right age of child bearing and this leads to high total fertility rate.
When a family improves its economic status the nutritional level generally increases. This increases the fertility of women as diet is crucial in women's fertility. Education also increases the awareness and gives access to people regarding information about antenatal, post natal care as well as care during pregnancy. The decreasing total fertility rate is one of the main goals of National Population Policy 2000.
