Year 12 Population Pyramids

Have a look at this great interactive website which immediately constructs population pyramids for every country for every 5 year period since 1950.

Look at a range of countries that interest you (you will need to select and discuss three for your homework) and ensure that you could describe and explain what is going on in any one year but also over time (temporally). 

Dont forget for your IB exam, you need to be able to describe and explain any trends you see.
