How Many Houses Are in the World?

Based on a global average of four persons per family and a demographic growth factor of 7% applied to the world’s total population across all time.

There are around 2.2 billion anticipated residences in the world as of the year 2021. It depends on the number of people living there.

And the square footage of the dwelling. More homes are constructed when there are fewer people living in each one.


How Does the Global Population Differ from the Global Total of Households?

Our estimate of 2,300,000,000 homes is based on global census data collected over the past 20 years. We’ve factored in population growth since each estimate was made to arrive at our final tally.

It’s consistent with population growth, and it depends on the average size of American households. More homes can be built if families can live in them.

As we will see in the following sections, the increasing number of homes is outpacing the rate of population growth because of the relatively new phenomenon of lower household sizes in western nations.

How Many More Houses in The World Are Needed to Build?

The world’s population is expected to double by the end of this century, from about 3.6 billion to about 7.2 billion.

The United Nations predicts that by 2100, the world’s population would have risen to over 11.2 billion from its estimated 7.6 billion at the end of 2017. That’s what we call “medium growth,” by the way.

Seven times the current 511 million people who live in the countries of the European Union (before Brexit) would put the same strain on infrastructure and development, not to mention material resources.

As the world’s population continues to grow at a rate of 45 million per year, there will be a corresponding increase in demand for resources such as food, water, and materials, most importantly, shelter.


As a result of the existing and projected need for new homes, governments are actively seeking to promote new developments in “offsite”.

Prefabricated – construction methods to increase the rate at which new homes may be built.

For the future, offsite building has been given a lot of attention in the UK’s Industrial Strategy, which was published in November 2017.

Over the past decade, this industry has expanded dramatically as new markets emerged in the healthcare, educational, and commercial construction sectors.

However, finding new approaches to the issue is necessary if prefab construction is to meet the demand for more homes at a faster rate. Thanks for read our Article How Many Houses Are in the World.
