Cities with high populations tends to have a lower population change: example: sudan has a population change increase of 30% - 40% compared to tokyo (biggest city on the planet) with an increase of about 10% Reasons: poverty is more evident in less urban cities, so people need to have more offspring to provide for them when they get older (in. Australia has literacy rate of over 95% and scores 0. 9 (high) on the hdi. Sudan has literacy rate of under 40% and scores 0. 5 0. 6 (low) on the hdi. Angola life expectancy is under 50 years, with fewer than 10 doctors per 100,000 people. Canada life expectancy is over 75 years, with over 300 doctors per 100,000 people.
