This project has been inspired by a Hacks/Hackers meeting in Brussels. After the meeting, I looked after interesting data sets and found out that it was not easy to find population pyramids for every country in the world, while the needed data was available on one UN website. There a lots of interesting points to see in there : - one can easily spot the future public retirement plans problem in Europe (with more and more elderly people ). See here for example : http://populationpyramid.net/?country=Belgium&year=2050 http://populationpyramid.net/?country=Belgium&year=2050 - I am still wondering what is happening in countries like Qatar in 2010 (http://populationpyramid.net/?country=Qatar&year=2010 http://populationpyramid.net/?country=Qatar&year=2010) How come there are so many more men than women ? - Near 1950 in Europe, you can spot the "dent" made by WW2 in the population, plus the baby boom. Example : http://populationpyramid.net/?country=France&year=1950 http://populationpyramid.net/?country=France&year=1950 - It is already interesting to compare the shape of the pyramid for countries like Afghanistan in 2010 (http://populationpyramid.net/?country=Afghanistan&year=2010 http://populationpyramid.net/?country=Afghanistan&year=2...) VS the US in 2010 (http://populationpyramid.net/?country=United_States_of_America&year=2010 http://populationpyramid.net/?country=United_States_of_Ameri...). One can easily see the difference in development, to say the least. And so on...

  The men in Qatar are most probably migrant workers. And marked dent you see in the 30 to 34 bracket in western europe in 1950 is not from WW2, but from WW1 (reduced births due to absent men).

    Very interesting, thanks !

      The "Australia/New Zealand" link seems broken - it prompts a refresh back to "World" when I select it.

        Ooops, yeah. Thanks for the bug report. I will fix that.

Hey, would it be possible to get these with absolute scale, not only the relative percentage? It will be interesting to see processes such as "baby-boom" over time.

  That is a good idea. This is in fact already in my idea list for this project amongst : - offering the ability to compare two pyramids, for example, - allowing to embed a pyramid in a distant site (I am sure people would like to blog about some pyramids) - adding a curve showing the population size evolution - exploiting the wealth of other data available on the UN website. There is for sure something interesting to do with the available migration rates for example - allow to add comments that could explain the shape of certain pyramids - add coordinate informations when hovering over a data point I will probably do some of those things, but I have lots of projects going on...

Please label the axes. http://en.wikipedia.org/wiki/Population_pyramid http://en.wikipedia.org/wiki/Population_pyramid It typically consists of two back-to-back bar graphs, with the population plotted on the X-axis and age on the Y-axis, one showing the number of males and one showing females in a particular population in five-year age groups (also called cohorts). Males are conventionally shown on the left and females on the right, and they may be measured by raw number or as a percentage of the total population. http://xkcd.com/833/ http://xkcd.com/833/ kb

  Will do. Or add a link to this wikipedia definition, which matches perfectly what has been done.
