SDG 11: Sustainable cities and communities Make cities and human settlements inclusive, safe, resilient and sustainable

While the proportion of urban population living in slums declined slightly, from 25.4% to 24.2% between 2014 and 2020, the total number of slum dwellers continues to rise with increasing urbanization. As of 2020, nearly 1.1 billion people lived in slums or slum-like conditions in urban areas, with an additional 2 billion expected to live in slums or slum-like conditions over the next 30 years.

Today, 85 per cent of slum dwellers are concentrated in three regions: Central and Southern Asia (359 million), Eastern and South-Eastern Asia (306 million), and sub-Saharan Africa (230 million). Data from 2022 reveal that only 51.6% of the global urban population has convenient access to public transport, with considerable regional differences.

In the developing world, an estimated 1 billion people still lack access to all-weather roads. Global cities expanded physically faster than their population growth rates, with average annual land consumption rates of 2.0% compared to population growth rates of 1.6% from 2000 to 2010, and 1.5% compared to 1.2% respectively from 2010 to 2020, according to data from 681 cities between 1990 and 2020.
