Population profiles, sometimes called population pyramids, are graphic representations of national population data. The name "population pyramid" likely came from the way these profiles look for developing countries whose base of young boys and girls is very large compared to its population of elderly people which is likely very small due to lower life expectancy. The population profile of developed countries take on a different form though, as children become financial burdens rather than assets and people live longer due to better access to medicine and healthcare. The population profile of Germany, seen above, shows the trend of negative population growth in the country, with less young people than middle-aged people. These profiles can be useful tools in a variety of fields.
