Pakistan and Spain have differences in population data. One of the factors that cause this is the country’s economy. For example: Spain has a better economy than Pakistan, so infant mortality rate will differ from Spain and Pakistan. Since Spain is a wealthy country, the people would have better uses to have children, which prevents the babies from dying. In Pakistan, which has poverty in the country, the people would not have the money or tools to keep sick children alive. To continue, a country’s education to its citizens can affect natural increase rate. In a country like Spain, its citizens will have more education, and with education comes knowledge about things such as contraceptives (birth control). In Pakistan, where there is less education, its citizens will not know much about contraceptives, which leads to many births. Contraceptives halt many births, and without them, natural increase rate would skyrocket.
