The given diagram illustrates data on the distribution of households in the UK based on the number of occupants in two different years.
Looking at the chart, the majority of households were occupied by two people, while only a marginal percentage housed six people. Additionally, the proportion of single-occupant and two-occupant households increased over the years, while the remaining categories decreased slightly.
In 1981, two-resident households held the largest share at 31%. This figure rose slightly to 34% over the next two decades, remaining the dominant household type. Meanwhile, three-person households were the next most popular household category, with 20% of homes falling into this group in 1981. However, this number declined marginally by 3% in 2001, being surpassed by single-person homes. Similarly, four-resident homes comprised 18% of UK households in 1981 before falling to 15% by 2001.
Concerning the remaining categories, single-person households made up 17% of all UK homes initially, but then surpassed three-person and four-person households as the second-most popular household group by 2001, rising to 26%. By contrast, five- and six-occupant homes were the least popular modes among the British, initially accounting for 8% and 6% of homes each, before dropping slightly to 6% and 2%, respectively by the end of the studied period.
