The population of the United States in 2005 was approximately 295,500,000 and the land area was 3,806,000 square miles. The population increased by 5.1% in 2015. To the nearest whole number, how much did the population density, in people per square mile, increase from 2005 to 2015?

4 people per square mile

Step-by-step explanation:

Population density = number of people divided by land area.

Back I 2005,the population density of the US was: 295500000/3806000= 77.6 people per square miles.

If the population increased by 5.1%,the new population of residents in the US will be

100% + 5.1% = 105.1%

105.1/100 × 295500000

= 310,570,500.

--- The new population density of the US in 2015 will be

310,570,500 ÷ 3,806,000

= 81.6 persons per square mile

To find out the difference in population from 2005 to 2015,we have to do nothing else but subtract the Population Density (PD) of 2015 from 2005

81.6 - 77.6 = 4 persons per square mile
