Two billion homes needed in next 80 years

By the end of this century, the world’s population will have increased by half – that’s another 3.6 billion people. According to the UN, the global population is set to reach over 11.2 billion by the year 2100, up from the current population which was estimated at the end of 2017 to be 7.6 billion. And that is considered to be “medium growth”.

The upscaling required in terms of infrastructure and development, not to mention the pressure on material resources, is equivalent to supplying seven times the population of the (pre-Brexit) European Union countries, currently 511m. With the global population rising at 45m per year, comes the inevitable rise in demand for food, water and materials, but perhaps most essentially, housing.

Housing needs are changing

Average household sizes vary significantly between different continents and also by country. According to the UN, recent trends over the last 50 years have also shown declines in household sizes.

For example, in France, the average household size fell from 3.1 persons in 1968 to 2.3 in 2011, the same time the country’s fertility rate fell from 2.6 to 2.0 live births per woman.
