Some places are experiencing large population growth such as South America and Asia however places in Europe such as Italy and Germany are having the opposite.

Its difficult to predict later figures as you never know whats going to happen as a country may break out in war,famine and population may decrease or countries coulf introduce a pro or anti natalist.

Italy case study

Italy has a large population of elderly dependents because of the things such as life expectency has changed as it is a developed country with a lot of resources. It has an impact of there not being enough workers and more money has to be spent on pensions and care for the elderly. A response the Italian government have had to this is introducing a pro natalist policy where if you were to have a child you would get icentives such as money.

China case study

China had to introduce an anti natalist policy because there population was getting dangerously high and if it carried on resources would have become sparse. It works by that every family can only have one child to reduce the population size. The advantages of this are the population is slowly decreasing which will prevent things such as resources being lost and things such as famine happening. A disadvantage would be that kids grow up without aunties or uncles and no cousins or siblings. Also some women will be forced into aborting there second child and this can be done in gruesome ways.

Some diadvantages of tbhis policy would be that people such as Isis can just come into the country and cause trouble. A advantage would be that people such as refugees can seek refuge in that country and can be safe.

Point based system.

A point based system is where people such as doctors would get more points than someone who was unemployed to get into a country as it works by if you were a doctor and you were needed in the country but say someone was unemployed they wouldnt be needed so they may not be let in.

impacts of migration

on the host country where the immigrant is migrating too it can have a positive affect as they may do work other people dont want to do or they could be something like a doctor/teacher. However it could be bad for the country as that could be more money that would have to be paid out for healthcare or education.

The origin could be affected as the people that are leaving could be vital for some things such as farming or stability for families as it could be a developing country. Or it could be that its a good thing for the country as they could be really overpopulated.
