Some of the factors that affect the birth rate in a given country include:
- Governmental policies (whether the government is pro-natalist or anti-natalist) - Countries like Japan and Thailand have natalist governments giving their citizens special incentives for bearing more children. China’s one-child only policy is the perfect example of anti-natilism.
- Social Beliefs - This is usually heavily intertwined with religious beliefs since the predominant religion in the region affects society. Birth statistics can become skewed where there is gender/sex preference. For example, in certain countries female children are deemed worthless so that killing female infants before their births are even declared is common enough to affect birth statistics.
- Religious Beliefs - Countries wherein the predominant religious belief is against contraception can be expected to have higher birth rates.
- Abortion Rates - Abortion rates are affected by the other factors that affect birth rate.
- Poverty/Economic prosperity - The ironic thing with this factor is that even though those that are more prosperous can afford to have more children they are usually the ones that have less, while poor families often have more children.
- Literacy (with special emphasis on female literacy)
- Infancy mortality rate - Countries with higher infant mortality rates generally have higher birth rates since families make it a point to have more children since the children are more likely to die.
- Conflict - Pertaining to war, security, safety.
