Country chosen: <u>Botswana </u>
Botswana is a southern African country with a relatively small estimated population of 2,352,000 in 2020. Their population Pyramid is <u>Expansive</u> in shape which means that it is wider at the bottom and smaller at the top which indicates that there are more young people than old in the country.
It points to a higher fertility rate than life expectancy which means more babies are born vs people living to very old age which means that the population growth rate is relatively high.
It would also appear that the population of both males and females are more or less balanced but women on average live longer than men judging by the higher proportion of women compared to men in the older age bars.
