Demographic changes are the primary impetus for pension reform initiatives throughout Europe and worldwide. You may use the model below to simulate the aging of Macedonia's population. Click on the arrow to choose the year for which you would like to see the demographic structure of the population. The vertical axis represents age (from youngest at the bottom to the oldest on the top, 0-100), and the horizontal axis represents the number of persons of a particular age. If you cut the horizontal axis in half with an imaginary line, the left part of the lined figure represents the male population with the right part representative of the female population. The shorter the lines, the fewer people of that particular age. The exact number of population is not represented on the model for simplicity. Notice that the population slowly changes shape in the future. Initially, the population is shaped like a pyramid, with many young persons and fewer older persons. Demographic changes, however, gradually increase the number of elderly relative to the younger population.

The output box under the population graph shows the ratio of the population over 60 to the population between ages 18 to 59. Over the years, the ratio increases showing that the number of people over 60 years has increased in relation to those between 18 and 59.
