American Centroid Helps To Trace Path Of U.S. Migration

American Centroid Helps To Trace Path Of U.S. Migration | Geography Education | Scoop.it

"David Greene talks to writer Jeremy Miller about the American Centroid. That's the place where an imaginary, flat, weightless and rigid map of the U.S. would balance perfectly if all 300 million of us weighed the exact same."

Seth Dixon's insight:

Every 10 years the centroid (the center of U.S. population) is calculated using the latest census data.  As the map above shows, the centroid has continued moved west throughout history, but in the last 60 years has moved to the south and west.  The recent shift to the south coincides with the mass availability of air conditioning (among other factors) which opened up the Sun Belt.  In this article in Orion Magazine, Jeremy Miller discusses the historical shifts in the spatial patterns of the U.S. population and the history of the centroid.  you can listen to podcast versions of this article as well, one by NPR and a much more detailed one by Orion Magazine.


Questions to Ponder:  Would the centroids of other countries be as mobile or predictable?  Why or why not?  What does the centroid tell us?

Awesome way to show how the settlement of the US continues to move west with the population growing on the West Coast at a faster rate.  If you look at the biggest jump between 1850 and 1860 it shows the mass immigration into the US and the further migration to the western part of the US especailly with the gold rush starting in 1849.  Great littel piece of information.

The centre of population in the USA has moved further inland and southward compared to Australia. Comparing urbanisation in USA and Australia.

Informative, short podcast that details the changing migration of the US. This allows for the comparison of migration and time and the effects of migration over the years in the US.
