95. IN 2007 the US population was 302 million people IN 2012 it was 314 million people. Find for the population change per year. Actually, I cannot solve the per year population change since I dn;t have any data to based with. However, I can only show you the percent change of the population rate of 2007 compare to 2012. => 314 people and 302 people => 302 / 314 = 0.96 => 0.96 * 100% = 96% Now, subtract this to get the value of the increased => 100% - 96% = 4% Thus, the population from 2007 has increased to 4% in year 2012.
