Interactive population pyramids
An interactive population pyramid – named for its shape – shows the age structure of population by sex with changes over time. Its shape displays the type of the age structure of the given population:
- expanding pyramid: a population pyramid showing a broad base of young people – increasing type,
- contracting pyramid: an aging population – decreasing type,
- stationary pyramid: a population pyramid showing an unchanging age structure.

- 1950–2011: statistical yearbooks (data adjusted with the help of historical statistical time series), internal database
Interactive population pyramid of Hungarian regions (NUTS2) and counties (NUTS3)
This software displays the age structure by sex between 1980 and 2011, not only for the country, but for the seven regions, Budapest and the 19 counties, making it possible to look at and follow changes in the age structure of different territorial units.
Technical conditions
To visualize interactive population pyramid a browser software capable of showing so called SVG (Scalable Vector Graphics) format pictures is needed. Internet Explorer 9, Firefox 3.x, Opera 9.x, Safari 3.x and Google Chrome browsers (as well as the newer versions of these) are directly able to do this, while an extension called Adobe SVG Viewer should be installed for the browser Internet Explorer 6–8. Its installation, under Windows NT, 2000 and XP, may only be made by a user with an administrator authorization. The freeware Adobe SVG Viewer may be downloaded from the website of Adobe. Beyond that, authorization is needed to run JavaScipt command files in the browser.
If you can see the red “SVG” and “JavaScript” text after the colon, then your browser is able to show interactive population pyramids:
