Animal Family

Size
Natalism is the belief that human reproduction is the basis for individual existence, and therefore promotes having large families. Many religions, e.g., Islam, Catholicism and Judaism, encourage their followers to procreate and have many children. In recent times, however, there has been an increasing amount of family planning and a following decrease in total fertility rate in many parts of the world, in part due to concerns of overpopulation. Many countries with population decline offer incentives for people to have large families as a means of national efforts to reverse declining populations.
