Explanation:
When it comes to population policies, the world can be divided into two groups, one being the one that has policies to stop the population growth and the other that has policies to expand its population. Generally speaking, the Western countries and the Muslim countries are the ones that promote the expansion of their populations, though the reasons are different.
The Western countries face very low birthrates and aging populations, so they have such policies in order to experience a decline of their populations and to have enough labor force for their economies. The Muslim countries, on the other hand, are countries where the religious authorities have big political power, and as it has always been the case in such situations, there is policies in place for expansion of the population so that the religion has more power through more followers, and maybe even expand by attacking other countries in the future.
