Geographic mobility occurs when the production of goods in one geographical area is moved to another geographical area. Production of goods may shift from city and state and even to other countries depending on the ease with which resources can change locations. As production locations shift, workers relocate, causing either an increase or a decline in local populations. Population and economic reports measure this type of mobility by studying an area’s immigration, out migration, and net migration, useful in determining the economic effects of population mobility.
The term geographic mobility refers to the reallocation of economic resources. It is influenced by numerous factors, such as workers fleeing from weak job markets in search of more opportunities in stronger ones. The cost of living and home prices in a geographical area may affect population, with homeowners selling expensive homes, then moving to an area where homes are less expensive. Mobility generally increases during periods of recession and decreases when the economy is healthy, tends to follow unemployment rates and occurs not just on a national level, but on a global scale.
When measuring geographic mobility, experts commonly look to immigration numbers as a determining factor. Immigration refers to persons moving from their native country into another country and settling there. An increase of migrants in a given geographical area may cause settled individuals to move out, which can depress wages for those currently employed in that location. As the wages in a location decrease, the demand for housing increases, causing rents and home prices to rise.
Another measure of geographic mobility, out migration, means an individual moves out of one community, region, or country to live in another. Out migration from large cities can have devastating effects on rural governments, public service systems, and schools due to an increase in population not supported by the infrastructure. As people leave a community, job shortages may occur, leaving businesses such as hospitals understaffed or causing businesses to fold due to a loss of customers. Out migration can have similar effects as immigration on the local infrastructure, leading to collapse due to a loss of funds.
Net migration measures geographic mobility by the difference of immigrants and emigrants of an area over a period of time. A positive net migration means more people are entering a country, while a negative net migration shows more individuals leaving a country. Neither measurement gives specific reason for the cause of immigration or emigration. This measurement is useful in determining the possible effects immigrants may have on a given geographical location.
@pleonasm - It's easy to talk about it as though someone has done something wrong and in some companies, of course, they are moving because they want to make more money.
But for other companies, they have to move in order to stay afloat. Sometimes the city they were established in becomes more expensive, sometimes they need to move in order to stay competitive with other companies, sometimes there's another reason.
It's not always greed or shady dealings, sometimes staying put would mean everyone was out of a job when the company goes under. In that case, being geographically mobile is a very good thing, because otherwise the company will cease to exist.
