The evolution of Population – Pyramids, Beehives, and Pillars. Oh My!

     The majority of Population growth in developing countries has followed a general trend in the 1950’s to this day.By comparing populations by age groups and sex we can see that in the 1950’s the population had a pyramid shape. One of the driving forces of the pyramid effect was the lack of knowledge in contraceptives which causes a baby boom and an increase of the younger generations.


As time progresses you can see a change in the shape of the curve from the pyramid to Beehive shaped and eventually to a pillar formation. With the rise in education, the younger population decreases and with better medicine availability the older generation increases.This isn’t like an already developed country. For Example the UK has over the same time span remained in the beehive state and future trends show that it would reach a stable pillar state. The evolution of population shows a more stable growth pattern, but only time will tell what will really happen.

    The driving force I mentioned (lack of knowledge) ties into the fertility rate. If the fertility rate is below in which is needed to replace both parents (2) then there is a decrease in the young population. Many countries have fallen victim to this and have there population has decreased tremendously.
