This KS3 Geography quiz challenges you on population. In a discussion about population, you may hear the words immigrants and immigration. These words are used to describe people who have moved from their country of birth to a different country. They are also sometimes referred to as expats (short for expatriates), depending on who is talking about them. There are many different reasons why people move countries. These include push factors like war, famine or natural disaster and pull factors like better job or educational opportunities.
Most countries do not control their population - an important exception that you need to be aware of is the People's Republic of China. Between 1949 and 1976, China's population almost doubled. The Chinese government feared that if this continued, there would not be enough food to feed everyone so they introduced mandated population control. This was in the form of a 'one child' policy in which families having two or more children were fined heavily. This was changed in 2015 to allow Chinese couples to be able to have two children without being punished.
