Answer:
Turn upside down
Explanation:
In the past, families tend to have a lot of children since most of their economies revolved around agriculture , so having more children typically resulted in more workers for the field.
This make the demographic pyramid for people who grows old could be 5 times the initial amount from each generation.
If the families keep having less than 2 children, the number of mortality rate will outpace the fertility, which will turns the pyramid upside down.
