Question

In a particular city in one year, the birth rate is 25 per 1,000 people. The death rate per 1,000 people`color(blue)(" is 17 per 1,000 people")`. What is the city's annual population growth?

Answer 1

Annual population growth rate: `color(blue)(0.8%)`

Explanation:

If the population increases due to births by 25 people
and decreases due to deaths by 17 people
per 1,000 people (assuming the net number of people moving into and out of the city is zero)
then
for every 1,000 people the population will increase by `25-17=8` people.

As a percentage growth rate:
`color(white)("XXX")8/(1,000)=0.8/100=0.8%`
