Use the information to calculate birth rate, death rate and population densities
serg [7]

The birth rate is 4.8%, the death rate is 4% and the population density is 50 people per km²

<h3>Population density</h3>

Population density is the concentration of individuals within a species in a specific geographic locale.

1) Birth rate = Births / population = 12000/250000 = 0.048 = 4.8%

2) Death rate = Death / population = 10000/250000 = 0.04 = 4%

3) Population density = Population / area = 250000 / 5000 km² = 50 people per km²

The birth rate is 4.8%, the death rate is 4% and the population density is 50 people per km²

The birth rate is 4.8%, the death rate is 4% and the population density is 50 people per km²
