**Population Movement** In 2008 the population of the United States, broken down by regions, was 54.1 million in the Northeast, 65.7 million in the Midwest, 112.9 million in the South, and 70.3 million in the West. The table below shows the population movement during the period 2008– 2009. (Thus, 99.23% of the population in the Northeast stayed there, while 0.16% of the population in the Northeast moved to the Midwest, and so on.)^{15}
