This worksheet is designed to work with the web-based world mapper resource - an ingenious programme that distorts the world map according to the prevalence of certain factors. For example, if cholera deaths was the selected factor, Africa would be hugely increased in size on the map, whereas North America would shrink to become almost invisible. This worksheet allows students to see the impact of various factors of their own choosing on birth rate, death rate and overall population size. A great way for students to find out for themselves how various factors affect the global population. Key words: Population, geography, death rate, birth rate, disease, economics, religion, biology, map, world, earth, continent, countries, europe, north america, south america, asia, oceania
