Population Pyramids of All Countries (1950-2100)

Some highlights:<p>- extreme gender imbalance in Qatar (probably due to migrant workers) : <a href="http://populationpyramid.net/Qatar/2010/" rel="nofollow">http://populationpyramid.net/Qatar/2010/</a><p>- Very clearly aging population in Japan : <a href="http://populationpyramid.net/Japan/2010/" rel="nofollow">http://populationpyramid.net/Japan/2010/</a><p>- People dying quite young in Afghanistan: <a href="http://populationpyramid.net/Afghanistan/2010/" rel="nofollow">http://populationpyramid.net/Afghanistan/2010/</a><p>- Clear impact of WW2 in Europe in 1950 on the 20-30 age class: <a href="http://populationpyramid.net/EUROPE/1950/" rel="nofollow">http://populationpyramid.net/EUROPE/1950/</a><p>The projections past 2010 are interesting too but they tend to smooth the curves which is probably not very realistic, as seen from the past. Nevertheless, it's interesting to see that the population of some countries has already started to shrink, like Russian Federation: <a href="http://populationpyramid.net/Russian+Federation/2010/" rel="nofollow">http://populationpyramid.net/Russian+Federation/2010/</a>

A big take-away for entrepreneurs in the developed world is the rapidly aging nature of our population - and the opportunities that may exist because of it.<p>The huge glut of baby-boomers retiring (while there are much fewer young people to support them/their institutions) is going to strain lots of existing systems (healthcare, retirement stuff, pensions, etc) - seems like a big opportunity for 'grey-power' software / tools.<p>Importantly, these upcoming retirees have at least a bit of fluency with software (compared to a generation ago), and at could least handle iPad-like tools (touch, big buttons, etc).<p>I mean, look at Canada's "pyramid" (<a href="http://populationpyramid.net/Canada/2010/" rel="nofollow">http://populationpyramid.net/Canada/2010/</a>) - a society with that kind of shifting demographic will need all kinds of new tools to help deal with the added strains.

I wonder what countries like India and China will do -- There's a massive gender imbalance in those countries; and in a decade or two; there will 50 million men (in India alone) who are unable to find a mate. Ideas/suggestions/thoughts on this issue?<p>EDIT: I deduced the ~50 million statistic from the 1.07 sex ratio for the 15-64 age range reported by the CIA[1].<p>For China, it's amazingly 1.17 for the same age range (!!! WTH -- that translates to 170 million surplus men!). What are these countries going to do?<p>[1] <a href="https://www.cia.gov/library/publications/the-world-factbook/geos/in.html" rel="nofollow">https://www.cia.gov/library/publications/the-world-factbook/...</a>

As a fun exercise, check out all of the countries where the "Arab Spring" has been taking place (e.g. Iran, Tunisia, Libya, Egypt). All have a characteristic "bulge" around the 20 age range.<p>There is a tendency for infant mortality to drop (as a consequence of better health care) before fertility does (as a consequence of improved standard of living). The result is a bulge, and as these bulges come of age, they usually lead to revolution...

The problem with projecting forward is that we have no idea what trends birth/immigration rates will take over the next century. Looking historically, it's clear that birth rates expand and contract cyclically, but this visualization seems to assume a fixed birth rate going forward so that all the hourglass trends smooth out and you end up with bottom-cropped sausage no matter where you start out.

The animation here irritates me. If you change the date by five years the graph points should scroll vertically (and adjust horizontally as necessary), otherwise it just makes it harder to see how the pyramid changes over time.

Not only will the shape be more and more condom-like (which I'm blaming for the drop off in birth rates in developed countries), but apparently an increasing number of folks will live over 100 in 2100, e.g. <a href="http://populationpyramid.net/Japan/2100/" rel="nofollow">http://populationpyramid.net/Japan/2100/</a>

All the African nations have huge birthrates<p><a href="http://populationpyramid.net/Niger/2020/" rel="nofollow">http://populationpyramid.net/Niger/2020/</a><p>10-15yrs from now that is a big workforce.

Very interesting! Nice website.<p>Suggestions: Create an easy way to compare a country pyramid with an average pyramid.<p>Make it easy to compare two or more countries in one graph.

How was the Soviet Union population dispersed throughout the timeline? For instance, Georgia has all the previous times populated with their own population.
