In 2007, the U.S. population was 302 million people. In 2012, it was 314 million. What was the rate of population change per year?

Answer 1

(314m -302m)/(2012-2007)

=12 x 10^6/5

= 2.4 x 10^6

= 2.4 million per year

2007 - 302 m

2008 - 304.4 m

2009 - 306.8 m

2010 - 309.2 m

2011 - 311.6 m

2012 - 314 m
