and a tighter yet growing economy. On the other hand, a country with a lower migration rate will most likely lose many of its available resources due to a lack of consumerism and production. Conflicts can arise due to migration, but people can still find it easier than ever to move to a different place. This can be due to more advanced technology and being able to communicate and have more efficient forms of transportation. All of this creates more opportunities which then increases the amount of net migration. The United States is an example of a country with growing opportunities as migration increases. Other occurring problems caused by net migration is a rise in the dependency ratio, higher demand on government resources, and public congestion. A high dependency ratio can be a factor caused by net migration. The dependency ratio can increase as the elder population increases and the fertility rate decreases. This results in a decrease in the labor force and this can hurt a country's economy by causing it to slow down. In order to slow down this process countries have many things, such as increasing the retirement age in order to keep the elderly involved in the workforce as much as possible.
