ANALYZING POPULATION PYRAMYD

A population pyramid is a tradicional way of visualizing and explaining the age extructure of a society. It is a graph that shows the estructureofa society by sex and ageat a given time and place.

Before getting into the pyramid analysis we can divede the pyramid into three different parts: Young dependents (0-14 years old), Working dependents (15-64 years old) and Old dependents (65+ years old).

Now we are going to start with the analysis of the pyramid. We have to take into account of diferent factors (sex structure, age structure...)
Regarding to he sex structure we can point that its true that more boys are born tan girls. But both sexes are equal at 45 to 49 years old.
However womens have more life expentancy because if we see the graph at 84 years old are more womens than mens. This is because mens have a higher metabolism so the body gets older before. Also in this countries mens are fighting in wars so more womens arrive to old ages.

In the other hand we have the age structure. Regarding to this factor we can see that is a young
population with very high natality, a big infant mortality and low life expentancy. This data coresponds to a country that is in the first step of the demographyc transition model, so we can say that is a population pyramid of an less economical developing country (LEDC).
Also we realize that there are bars that go in or out anomalously in the graph. For example, we can see a starter between 5 and 9 years old, it could be caused by an epidemic or illness that increased infant mortality. Or between 10 and 14 years old we can see an outgoing that was caused by a time of prosperity in which the birth rate increased.

Finally, observing the information of the graph we can deduce some consequences of the demographic structure and possible solutions. We saw a high death rate and very high natality. And like we said before, this data is from a LEDC in the first fase of the demographic transition.
We can also predict the demographic evolution of the country. Little by little it will begin to decrease the death rate and later, the birthrate. Until it happends population will increase and over the years the country will pass through all phases and it will come to where today there are many countries like Spain, with a aeging population.
