The ratio of 50-year-old men to 50-year-old women

Explanation:

Population pyramid is a graph organized to classify the population of a given locality according to age groups, dividing them by gender. Therefore, with the population pyramid it is possible to determine the proportion of 50-year-old men and 50-year-old women.

This chart is formed by overlapping bars that focus around an axis. The lower bars represent the younger population and the upper bars represent the older population. On the right side of the axis, the female population is always quantified and, on the left side, the male population.

Population pyramids are important in developing medium - and long-term public planning. For example, if the age structure of the population indicates that there are a large number of young people with high birth rates, it is necessary to implement policies that address the inclusion of age groups in the future, with measures that aim, for example, to for example, the expansion and improvement of day care centers and schools.
