Understanding the Population of a Country and Potential Changes for a Government.
‘’Understanding the population structure of a country and potential changes is extremely important for governments. Using examples explain this statement.’’
A population pyramid is an illustration that shows the distribution of various age groups and gender in a population-typically a country or a region. It can be drawn up for any area, from a whole continent or country to an individual town, village or city. They are also used in Ecology to determine the overall age distribution of a population; showing indications of that groups reproductive capabilities. A population pyramid typically consist of two back-to-back bar graphs, with the population plotted on the Y-axis (one showing the number of females and the other showing the number of males in a particular population in five year age groups- also called cohorts). Knowing the percentage of people in these sectors can allow us to calculate the dependency ratio. There are two groups of dependants; young dependants (aged below 15) and elderly dependants (aged over 65). Dependants rely upon the economically active for economic support. Population pyramids are often viewed as the most effective way to graphically analyse the age and gender distribution of a population as they are presented as a clear image. There are different shapes to the pyramid which tells us different things about the population. A lot of information about the population broken down by age and gender shows many aspects of it, such as development, its birth and death rates as well as the life expectancy. While all countries' population pyramids differ, three types have been identified by the fertility and mortality rates of a country. A Stationary pyramid shows an unchanging pattern of fertility and mortality. A progressive pyramid shows a high birth death rate. A regressive pyramid shows a decline in birth rate and a low mortality rate. Population pyramids can be used to find the number of economic dependents being supported in a particular
