What can population pyramids tell us about the economic or demographic situation of a country?
Community pyramids are important graphs for visualising how communities are composed when looking a groups separated by age and sex. In population pyramids, three patterns exist: expansive, constrictive, and stationary.
To measure disparities between the male and female populations of a region, a population pyramid may be used. They often indicate the number of dependents at any given moment (children and, often, elderly people) and the overall population composition.
Population pyramids are useful for studying the future of an area as well as analysing past and present population patterns. The graph would provide a way to imagine how the future population will be impacted if part of the population has been impacted by abrupt shifts, such as military war deaths, high female mortality during childbirth, or the relocation of young workers from impoverished areas. They will also aid with the direct delivery of resources to areas by government and private enterprise depending on community needs.
