Net migration rate
The net migration rate is the difference between the number of immigrants (people coming into an area) and the number of emigrants (people leaving an area) throughout the year. When the number of immigrants is larger than the number of emigrants, a positive net migration rate occurs. A positive net migration rate indicates that there are more people entering than leaving an area. When more emigrate from a country, the result is a negative net migration rate, meaning that more people are leaving than entering the area. When there is an equal number of immigrants and emigrants, the net migration rate is balanced. The net migration rate is calculated over a one-year period using the mid year population and a ratio. Migration occurs over a series of different push and pull factors that revolve around social, political, economical, and environmental factors according to Migration Trends. Social migration is when an individual migrates to have a higher standard of living, to be closer to family, or to live in a nation with which they identify more. Political migration then is when a person is going in as a refugee to escape war or political persecution. This form of migration can also be called forced migration. This happens when refugees are moving to neighboring countries or more developed countries. Neighboring countries, especially the ones in the middle east are dependent on to shelter the refugees. Just like the United States, many of the more wealthy countries are now the hosts to many of these refugees. Economical migration is moving to a place where one can aspire to have a career and better job opportunities which end up contributing to better living conditions. Lastly, environmental migration is when natural disasters force you to move into a new area. By analyzing all of the migrating factors you can get to the idea that the net migration rate can say a lot about a country. For example, if there are a lot of people coming in and not many leaving it can be assumed to be a wealthy country that keeps evolving and generating more and more opportunities. On the other hand, if few people are coming in and many are leaving it can be assumed that there is a possibility of violence, low economy, or not enough resources to fulfill the existing population.
