Factors affecting birth rates and death rates
Population growth
Projected world population and growth rate from 1950-2050
The population of the world was relatively low and steady until the 1950s when there was a population ‘explosion’. Since then, there has been a rapid increase in the world’s population so that in 2011 it passed 7 billion. The majority of this population growth is, again, in the developing world.
The reason for this rapid expansion is mainly due to the decrease in global The number of people who die per thousand per year. while The number of babies born per thousand women per year. remained very high. This meant that many more people were being born than were dying so the population grew. This difference between birth rates and death rates is called the The natural growth of a population due to the number of births exceeding deaths..
