Why some areas of the world are densely populated and others are sparsely populated.

do about it.    The main reason for world’s population changes is the change in birth and death rates. When birth rates are higher than death rates the population of an area will increase. Over the past 150 years in many places in the world there have been improvements in health care and hygiene. That has made a drop in the death rate. But the birth rates in poor undeveloped countries are low therefore in rich developed countries births rates are increasing. So the number of people in the world has and is growing rapidly.     Population density is a measurement of the number of people in an area. Population density is usually shown as the number of people per square kilometre. This map below shows population density. The darker the colour the greater the population density.        The map above shows that world population is unevenly spread. Some areas have a high population density while others have a low population density. Areas of high population density tend to be places with weather that’s not to hot, wet or cold. Also places with easy communications, also that have flat land, are rich, fertile soil, developed and ideal for farming, and on all of them reasons it also coursed migration into or out of the population.     If you compare somewhere like London, which is a rich developed area to somewhere like the Amazon Forest. There is a big population size difference. Even thought the overall population of the Amazon Forest is roughly around the same amount as London, if you compare it by the number of people per square kilometre London has a much bigger population.Places like Bangladesh and Western Europe have high population.This is because of their pleasant climate good water supply easy communications and flat land, rich, developed areas fertilise soil and good weather that is ideal for farming. In other places there is also high density because of migration moving people in to areas for work, better living conditions and all the others reasons that have been made above. Areas like the the Sahara deserts have a low population because of it climate which is too dry and hot for people to live in, and makes communications difficult. Himalaya Mountains also have less population because of the cold climate.As the years go on i think the population will carry on increasing rapidly .    There are several reasons that we can do to Change the Low density around the world for example introducing more education so more migrants can come into different counties. Sharing out the rescores instead of keeping them all in one place that will attract people to different areas and help stop migration. But places with conditions that are so bad that you can’t live in will never be changed and those places will always have a low density and stay a poor undeveloped counties.
