Now that we have returned for the New Year we begin our studies again in Population in year 9. This week we are going to compare population to a bath! If you are still puzzled by this then think of the water as people and think what the taps and plughole could represent, as you think about it more deeply, what about other things like the size of the bath or the overflow?
One of the important trends we have seen is that people are living longer. This has a big effect on the age of the population. We can see this effect on something called a population pyramid. We will be covering this over the next couple of weeks but if you want to have a look at what is predicted to happen and even have a play around with some possible outcomes try this out. Just click on start simulation, after 2050 you can use the sliders to adjust how long people live and how many babies are born. What happens for example if birth rate falls?
