- Women are now being taken more seriously.
- Large ammount of the population is over 65.
- More money is spent on Health care for the elderly which could be spent on things such as education.

- Italy has tried to encourage having babies with baby bonus. (pro natalist policy)
- Raising off age of having acsees to pensions.
- Making taxes higher to pay for the high demand of pensioners.
China's Anti-Natalist Policy
How it works:
- In china couples are only aloowed to have one child
- This one child has everything paid for by the government such as, education and insurance
- If however, the family decides to have another child they must pay the government a fine, the amount of how much the first child cost for education ect.
- Women can focus more on their work than looking after many children.
- No one is forced into poverty and over population.
- The child they have is well cared for.
- Children are raised without aunties or uncles.
- It's unethical to tell people how many children to have and how to raise their family.
- Children are abandoned, or sometimes killed, because people don't want to be fined and are scared or because they wanted sons instead of daughters.
