What percentage of households were rented in the UK in 1918?

The correct percentage of households that were rented in the UK in 1918 is 77%. This figure reflects the significant impact of historical events such as World War I and the socio-economic changes that followed. During this period, many people were living in rented accommodation due to factors such as housing shortages, urbanization, and the aftermath of the war, which led to a high demand for rental properties.

The widespread practice of renting was especially prevalent in industrial areas where workers needed accessible housing near their jobs. This context contributes to understanding why such a high percentage of households were rented at that time. The other options suggest significantly different figures, which do not align with historical data about housing in the post-war UK.
