Population+Pyramids

=World Populations= Understanding the speed and amount of how fast the human population on the planet has grown is essential to comprehending the challenge of a rapidly growing global population. For this to be understood you will be working on the exercise below (see document). Most of this is about interpreting graphic information. After viewing the film //The World in Balance (The Population Paradox)// this should be very easy. [|World Population Estimates from Ancient Times to 1950] and watch how fast the world's population is growing at [|Worldometers.]

=Population Pyramids=

Population pyramids tell us a lot about what stage of [|demographic transition] a nation is in. It gives us a good idea if the population is going to be growing rapidly and thus demanding services that might include, say, education or housing. Or it could tell us if the population has gone through a war, a famine or a serious disease. For the project below, you will need to go to several websites and refer to some of the information below. This is about understanding demographic transition and about understanding what a population pyramid is all about.

 * Rapid fall in each upward age group due to high DR. || Fall in DR so more people living into middle age. || An increasing proportion of the population is in the 65+ age group. || Higher dependency ratio. ||
