As a military wife, I am already used to moving. Moving has been part of our lives since we are associated with the military. Anyway, did you know that 6.7 million households in the States moved in the year 2010? And 15 percent of the population in the States moves every year, that is 4 times more than the population of Manhattan.
There are so many reasons why people move, it could be a new job? it could be for school? or just want a new scenery, but no matter what the reasons are moving is kind of hard and stressing.
Anyway, check out these websites http://moving.about.com/u/ua/preparingforyourmove/Why-Do-You-Move-Stories-About-Moving-Reasons-For-Moving.htm or http://www.census.gov/prod/2001pubs/p23-204.pdf when you have the time.
