Social impacts of population growth
- services cant cope with increase (eg healthcare) so not everyone has access to them
- Children have to work to support large families so miss out on education
- not enough houses so people forced to live in crowded communities of makeshift houses- health problems (e.g diseases from lack of clean water)
- food shortages is country cant grow/import enough food
Economic impacts of population growth
- not enough jobs for everyone so unemployment increases
2. increased poverty as more people are born into families that are already poor
Political impacts of population growth
- most of population are young so government focuses of policies important to them (eg education)
- fewer older people so government is not as focused on policies for them (eg pensions)
- government has to make policies to bring population growth under control so impacts dont get worse
What are the two strategies to help control population growth?
birth control programmes and immigration laws
What does a birth control programme include?
Some governments have laws as to how many children a couple can have, they also help couples plan/limit number of children (contraception and sex education) so the population wont get much bigger
What do immigration laws do?
limit the number of people that can migrate, also be selective e.g let in fewer people of child bearing age means fewer migrants having children. this slows down population growth rate
What is the population of China?
1.3 billion
When was china’s one child policy introduced?
1979
What were the benefits if you had one child?
Longer maternity leave
Better housing
Free education for the child
What would happen if you had more than one child?
There were no benefits and the couple would get fined part of their income
What were the exceptions and why?
Can have 2nd child if 1st is a girl/has a disability because more kids are needed to work on the farms. ALso, if one parent had a disability or both parents were only children then the couple could have a 2nd child as they need enough people to look after the parents
