the need for more housing
If 10000 persons of the population were examined and 450 people had babies, what would the annual birth rate be?
the annual birthrate would be 45.
To calculate the annual birth rate, you need to determine the number of births per year per 1,000 individuals in the population. Here’s how you can calculate it:
Calculate the birth rate per 1,000 individuals:
Birth rate = (Number of births / Number of individuals) * 1,000
Substitute the given values:
Number of births = 450
Number of individuals = 10,000
Birth rate = (450 / 10,000) * 1,000
Calculate the birth rate:
Birth rate = 45
Therefore, the annual birth rate would be 45 births per 1,000 individuals in the population.
What is the natural Increase?
This is the increase in population brought about when the birth rate exceeds the death rate.
How is natural increase calculated?
It is calculated by finding the difference between the birth rate and the death rate.
