World population

Year 10 have just started Population. We have started to look at the distribution of the world's population and played population top trumps. We also recorded the world population (using this world population clock) at the start of the lesson and at the end to see the rate at which it is increasing. Here's a couple of useful things related to population. Firstly, a BBC learning zone clip on 'Is the world's population spiralling out of control?'.

(Thanks to Odblog for highlighting this)

Secondly, this is the map that was used to describe the distribution of the most densely and sparsely populated places in the world. The map came from worldmapper where there's a whole host of similar world maps which have been resized to show different characteristics.

Finally, a fantastic tool using statistics to graphially show different characteritics of countries and their population. Here's one showing the relationship between life expectancy and income per person. The size of the circles shows the total population. Click on the graph to play around with the example one, or go to the gapminder site to create your own graph.
