the chart below shows the percentage of households in owned and rented accommodation in England and Wales between 1918 and 2011. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The bar chart compares the situation of household owning and renting in England and Wales over the period from 1918 to 2011.

Overall, the proportion of rented accommodation declined over the given period whereas the opposite trend was seen for households in owned accommodation.

In 1918, about 76 percent of families in England and Wales rented houses, which tripled the figure of those who owned their accommodations (24 percent). Over the first half of the period, there was a significant drop in the renting house percentage to exactly 50 percent in 1971. In contrast, the ratio of households in owned accommodation doubled (24 percent compared to 50 percent) and reached an equal figure of those who rent accommodation in 1971.

After a considerable fall in the next 30 years to just above 30 percent, the percentage of households in rented accommodation increased slightly by 5 percent between 2001 and 2011. On the contrary, the figure of families who owned accommodation grew sharply and reached a peak at nearly 70 percent in 2001, followed by a small decrease of 5 percent in the last 10 years of the period.
