There are numerous factors that contribute to migration, but all of them can be put in two wide categories, push factors and pull factors. The push factors are the factors that make people leave a certain place and move to another one. The pull factors are the factors that attract people to move into a certain place.
The Rocky Mountains can be considered as a push factor. The reason for this is that these mountains when compared to many other parts of the United States, offer very few opportunities and advantages. Especially when the large economic centers are taken into consideration, being in the same country, people naturally feel that they are missing out on a lot of things in life by living in the Rocky Mountains, so they move out of them and generally tend to migrate to the big urban areas.
