43. ● Population Distribution In 1980 the U.S. population, broken
down by regions, was 49.1 million in the Northeast, 58.9
million in the Midwest, 75.4 million in the South, and 43.2
million in the West.3 In 1990 the population was 50.8 million
in the Northeast, 59.7 million in the Midwest, 85.4 million in
the South, and 52.8 million in the West. Set up the population
figures for each year as a row vector, and then show how to
use matrix operations to find the net increase or decrease of
population in each region from 1980 to 1990.

down by regions, was 50.8 million in the Northeast, 59.7
million in the Midwest, 85.4 million in the South, and 52.8
million in the West.4 Between 1990 and 2000, the population
in the Northeast grew by 2.8 million, the population in the
Midwest grew by 4.7 million, the population in the South
grew by 14.8 million, and the population in the West grew by
10.4 million. Set up the population figures for 1990 and the
growth figures for the decade as row vectors. Assuming that
the population will grow by the same numbers from 2000 to
2010 as they did from 1990 to 2000, show how to use matrix
operations to find the population in each region in 2010.n In 1980 the U.S. population, broken
