The Westerly Migratory Blueprint Of The Usa

In every census since 1790 the hateful view of American population has moved westward. In 1790 the most populated cities inward the U.S. were all on the East Coast. By the 2010 census seven of the 10 largest cities were located inward the Sunday Belt portion of the S as well as west.


Perhaps i of the best mapped illustrations of this westwards shift inward the U.S. is this animated cartogram. In full general I'm non a huge fan of cartograms exactly this animated cartogram, showing US Population Trends Over The Last 220 Years, perfectly visualizes how the hateful view of the U.S. population has continually moved inward a westerly direction.

The map shows the size the population inward every U.S. province for every decade since 1790. The animated cartogram clearly shows the full general westward migratory designing of the American people over the concluding 200 years.


Another swell visualization of the westward migration inward the U.S. is this map from the U.S.A. Census Bureau. This animated map shows where the hateful view of the population has been for each U.S. census from 1790 to 2010.

The Mean Center of Population for the U.S.A. 1790 to 2010 shows how the hateful view of population inward the U.S.A. has shifted westward inward the concluding 220 years from Kent County, Maryland to Texas County, Missouri.


This shift is non solely evident inward the westerly moving hateful view of population inward the U.S. exactly every bit good inward the listing of the largest populated cities generated from each U.S. census. Josh Mahar has created an interactive map showing the tiptop 10 U.S. cities yesteryear population inward every census since 1790.

Using the Historical Look At America's Largest Cities map y'all tin terminate sentiment the tiptop 10 most populated cities inward each decade. The map sidebar every bit good shows the population for each of the tiptop 10 cities inward each census. If y'all plow on the annotations y'all tin terminate every bit good discovery out a lilliputian to a greater extent than virtually the changing populations inward the mapped cities.

Last calendar week I released a really similar map called Shifting Cities. In essence my map visualizes the same information used inward Josh's map. Both maps exhibit how the most populated cities inward the U.S. are increasingly probable to live on establish inward the due west as well as S of the country. However Josh's map is ameliorate than mine. His annotations are to a greater extent than detailed than the notes on my map. I every bit good similar the fact that Josh has used scaled map markers to exhibit the relative population size of each metropolis shown on the map.
