How Many Houses Are There in the World?

Housing is one of the most essential aspects of human life. It provides shelter, security, and a place to call home. With a growing global population, it is interesting to ponder on the number of houses that exist worldwide. While it is impossible to provide an exact figure, we can estimate the number of houses in the world by looking at various factors such as population, urbanization, and housing trends.

Estimating the exact number of houses in the world is challenging due to several reasons. Firstly, the definition of a house can vary from one country to another. In some regions, a house may refer to a traditional standalone structure, while in others, it may include apartments or other types of dwellings. Additionally, informal settlements or slums, which lack proper infrastructure, might not be accounted for in official statistics. Nevertheless, we can rely on available data and make informed approximations.

According to the United Nations, the global population surpassed 7.8 billion in 2020. With an increasing population, the demand for housing also rises. As a result, there has been a significant boom in construction activities worldwide. Urbanization, in particular, has played a crucial role in shaping the housing market. As people migrate from rural to urban areas in search of better opportunities, more houses are being built to accommodate the growing urban population.

To estimate the number of houses in the world, we can consider the average household size and the global population. The average household size varies across countries, with some having larger families and others smaller. According to the World Bank, the average household size worldwide is approximately 3.4 people. By dividing the global population by the average household size, we can obtain an estimate of the number of houses.

Using this calculation, we find that the number of houses in the world could be around 2.29 billion. However, it is essential to note that this figure includes both formal and informal housing. Informal settlements, often found in developing countries, are not accounted for in official statistics but make up a significant portion of the global housing stock.
