## Question 35 (7 of 7 Based on Passage)

Edit

### Write in Short

How birth rate and death rate are related to population?

### Explanation

The natural increase of population rate is mainly depending on the birth rate and death rate. Birth rate refers to the number of live babies born in a year for every 1000 people in the total population. Births occur to young-adult age people. If in a country there are more young-adult in comparison to the old adult, then there will be more births in a country leading to increase in population of the country.

On the other hand, if in a country older-adults are in large number then the country will have high mortality rates. Thus, we can say that, many people who are having one or two children can still produce many births in a country. This is referred to as population momentum. The momentum of population can be lowered in a less developed country when the large number of young-adults pass the age of fertility.
