The bar chart illustrates the quantity of individuals each family by percentage in the UK from 1981 to 2001. Overall, over three-member households were fewer than under three-dweller counterparts throughout the observed years. Notably, while the former experienced a downward trend, the latter exhibited a steady growth.
Upon closer inspection, in 1981 families featuring 2 people started with 31%, 14% higher than that for one-member ones, after which these figures increased to 34% and 26% respectively in 2001. In terms of households including 3 individuals, it recorded at 20% at the beginning, which subsequently underwent 3% decrease at the end of the period.
As for the remaining kinds of family, households who had four people began at 18% followed by five-dweller ones in 1981. Twenty years later, both the former and the latter exhibited a 2% to 3% decrease, particularly at 15% and 6% respectively. Ultimately, in 1981 six-individual families accounted for 6% , then declining to 2% at the end.
