- The effect of this is to raise the population in the upper age groups substantially.
Explanation:
The fertility increases the population and mortality decreases population because when more birth happens then, it's obvious that it will increase population and when more people died then, it decreases population but when the more death happens, it leàds to more birth indirectly and when more birth happens, it indirectly leads to more deaths due to lack of facilities of food, shelter, health facilities, etc. Ex for fertility: population in Terai region is dense as people give more births due to lack of education, occupation, nutrition and health, religious status and sometimes due to misscarriages or need of support for their old age. Now; Ex for mortality: when malaria spreaded in Terai region lots of death happened and lots of people out-migrated to be safe from malaria which caused decrease in population.
