in 1940, a certain country's population was 71,494,839 and its area was 2,998,769 square miles. in 2000, the country's population was 281,385,995
and its area was 3,683,493 square miles. compute the population densities of both years.

Answer 1

The population density in 1940 is is 24 people per square miles and population density in 2000 is 76 people per square miles

Population density is a measurement of population per unit area, or exceptionally unit volume; it is a quantity of type number density. It is frequently applied to living organisms, most of the time to humans.

Given,

The population in 1940= 71494839

Area= 2998769 square miles

We know,

Population density = Number of people/ Land area

Population density in 1940= $\frac{71494839}{2998769}$

= 23.84 people per square miles

≈24 people per square miles

The population in 2000= 281385995

Area= 3,683,493 square miles

Population density= $\frac{281385995}{3683493}$

=76.39 people per square miles

≈76 people per square miles

Hence, the population density in 1940 is 24 people per square miles and population density in 2000 is 76 people per square miles
