The table below shows how the time needed for one billion people to be added to the world’s urban population has decreased dramatically. Many aspects of urban change in recent decades are unprecedented – not only the size of the world’s urban population and its level of urbanisation, but also the number of countries becoming more urbanised, the size of their urban populations and, as the first three blogs in this series explored, the size and number of very large cities. Over the last 60 years, the number living in urban centres has grown more than fourfold today, the proportion of urban dwellers reaches 56.2%, compared to less than 15% in 1900 and 34% in 1960. The world’s urban population today is around 4.4 billion people – more than the world’s total population in 1975. This blog looks at the size of the world’s urban population, the scale of its growth and how its distribution has changed between regions and between countries.
