Population pyramids

The recent exercise on population pyramid construction was excellent especially the care in which all of year 9 took to make them as precise and as neat as possible. We shall be using all of the data in a forthcoming lesson to do some population calculations and work out dependency ratios, the population growth rate and the doubling time for our countries. Complicated stuff so you will need to bring your calculators.

This is an excellent website that has a wide range of animated presentations on population pyramids, measuring life expectancy and fertility as well as the global population and the importance of births and family size. It is nice and easy to navigate around and very user friendly.

There are some good visualisations of pyramids in a hundred year period between 1950 and 2050. Looking at how the populations of Europe, China and the USA are predicted to change. puts a lot of the work we have been doing into perspective, and makes it a little easier to understand.

We used the powerpoint below in the lesson on population Pyramids, but there were some places that it did get a little bit confusing so just to make sure you fully understand everything here it is again.
