Why does birth rate drop?

- Emancipation of women

- More available contraception

- Comfortable lifestyle: women may be happy with their social lives and career and are less likely to want to give it up.

- Lower Infant Mortality Rate: if there's more chance of infants surviving, people will have less children. This is due to vaccinations, healthcare and sanitation.

- Increased desire for material possessions: Having children is costly, it will affect levels of disposable income.

But the main reason why Birth Rate is lower is because of the old ONE-CHILD-POLICY that happened in China. There's less women and most women get jobs; not babies
