The given bar diagrams make a comparison of how figures for the family members altered in the United Kingdom in census year 1981 and two decades later.
It can be clearly observed that while the number of families comprising three or more members went through a declination, the rest of categories witnessed an upsurge. Noticeably, in both the years, it was the families with previously two people which had the highest count.
Considering the groups experiencing an increasing trend, we see that, with the an exponential rise of 9 units, the number of people living solitary life rose to 26 from its original level of 17; however, with a marginal one-third fillip families with exactly 2 members registered the maximum figures for any category (31 and 34, respectively in 1981 and 2001).
On the contrary, a detailed analysis of the demographic data reveals that all four remaining groups consisting at least three people under went a downward trend. Although, like the group of just two members, there was a marginal reduction of 3 families in numbers for the families with 3 and 4 persons each, the former had 15 members as against 17 for the latter in the final year of the survey. In terms of groups with 5 and 6 people each, it is apparent that the biggest family units declined to just 2 following a massive two-third downfall, as against only one-fourth fall noticed in families with 5 having only six families in the 2001.
