In January 2012, the US population was about 313 million people. In January 2017, it was about 324. What was the average rate of population change per year?

Answers

The average population change per year is 11 million

Final answer:

The U.S. population increased by an average of 2.2 million people per year from January 2012 to January 2017.

Explanation:

To calculate the average rate of population change per year, we first need to find out how much the population changed over the given period. In this case, the US population went from 313 million people in January 2012 to 324 million people in January 2017 - a difference of 11 million people over 5 years.

Next, we divide this difference by the number of years to find the average change per year. So, 11 million divided by 5 years equals an average annual population increase of 2.2 million people over this five year period.

This method of calculating average change is an important concept in demography, the study of populations, which considers factors such as fertility, mortality, and migration.
