This is fascinating. Using Census data, the authors of this post go back over one hundred years and create cool infographics showing us where residents living in a state in a given year were born.

The result is an amazing set of comparisons showing you which states are home to the most migrants, and where those migrants have come from over the years.

For instance, look at how Montana used to be comprised mostly of outsiders, with more than one in four coming from not just from another state but outside the country:

California’s domestic migration has constricted in the past couple generations even as it’s global migrants have held pretty steady:

Indiana is a pretty good picture of the pattern you see in the Midwest, which has been almost always the same in its proportion of native-born residents and those from outside the state:
