The World Population Pyramid displays age, sex and population data for 100 years. We have chosen the years between 1950-2050 for our Pyramid to show a balance of historical and future projections. Increases or decreases in death rates or in number of children born can affect these results. This Pyramid is a useful tool for the visual display of the changing population dynamics for virtually every country in the world. Use the list on the right to select other countries to review. United Nations 2015 data is used.
