Population Pyramid is an interactive tool that allows users to explore the population structure of a given country or region. It displays the population distribution by age and gender, and can be used to compare the population structure of different countries or regions. The pyramid also provides information on the population growth rate, fertility
A population pyramid or "age-sex pyramid" is a graphical illustration of the distribution of a population by age groups and sex; it typically takes the shape of a pyramid when the population is growing. Males are usually shown on the left and females on the right, and they may be measured in absolute numbers or as a percentage of the total population. The pyramid can be used to visualize the age of a particular population. It is also used in ecology to determine the overall age distribution of a population; an indication of the reproductive capabilities and likelihood of the continuation of a species. Number of people per unit area of land is called population density.
