Answer:
The mean center of population is the place where an imaginary, flat, weightless, and rigid map of the United States would balance perfectly if all residents were of equal weight. Historically, the movement of the center of population has reflected the expansion of the country, the settling of the frontier, waves of immigration and migration west and south.

Alaska and Hawaii were not included in the calculation of the mean center of population until 1950. Puerto Rico was not included in any decade.
