Birth and death rates are often reported as births or

deathsper thousand members of the population. What isthe relative

rate of growth of a population with a birth rate of 30births per

1000 and a death rate of 20 deaths per 1000?

10 growth per 1000.

Step-by-step explanation:

Given,

Rate of birth = 30 births per 1000

Rate of death = 20 deaths per 1000

As the growth in population is the difference in the number of the child take birth and the person die.

As we are calculating the rate of birth and rate of growth in per thousands of members, so the growth rate will be also in per thousands.

As we can see on every one thousand people,

total birth = 30

total death = 20

so, total growth = total birth - total growth

= 30 - 20

= 10

As at every 1000 persons, there are 10 persons survive, so the rate of growth will be 10 growth per 1000.
