ANALYSIS OF A POPULATION PYRAMID




A population pyramid is a traditional way of visualizing and explaining the age structure of a society. It is a graph that shows the structure of a society by sex and age at a given time and place.

The sex structure of this pyramid is very simple. At the base of it we can observe that there are more boys (34 percent of the total men in the pyramid were borned from 1999 onwards) between 0 and 19 years than girls (32.2 percent of the total women in the pyramid were borned from 1999 onwards). But later, in the period of 40-44 ther pyramid equilibrates and both sexes have the same percent, probably because men are less healthy and smoke more. At the top of the pyramid there are more women than men, this is not strange because it is proved that men die earlier than women because they do more forced works and are less healthier. 

The age structure of this country is shown by a pyramid with a mix between a triangular-shaped one and a bell-shaped one. This means the country is in developing ways and is economically growing (DC). Then referring to the notches and bumbs in this pyramid.
 Down in the base of the pyramid the notch of the 0-9 years group (2009-2018) is probably made by a natural disaster, because it´s a country in developing ways so an epidemic is not a very probable problem and it has a not so bad sanity sistem. Another probable disaster could be a mass migration because of a war or poberty. There is also a bumb that highlights in the group of years 25-34. This is probably caused by a baby boom, but this baby boom probably is not after a war because if it was caused by a war there would have to be a notch before that group of years around 1978-1974. That notch doesn´t exist so we can deduce that baby boom was caused by an economic prosperity. That bumb could also be made by immigration but I´m not likely to think that because people don´t migrate to countries in developing ways in that massive amount of people.

In conclusion, this country is situated in  the second part of stage 2, it has a high birth rate and a high life expectancy but the death rate won´t go lower. The next phase of this pyramid will be a bulb-shaped pyramid, the country will start having problems with an ageing population and decreasing birth rate. The government will have to start creating laws or making taxes for babies lower.
