The line chart depicts the number of people per household in the UK over the period of 20 years. Overall, the number of small families, 1 and 2 people per household, steadily increased during the following years, whilst households with 3 or more family members shortened over the period of time.
In the 1981, the largest number of people per family was households of 2, accounting for 31%, and families of 3, accounting for 20%. Families of 4 and 1 were practically the same and made up 18% and 17% of the total number. The smallest categories comprise of households of 5 and more, accounting for less than 10%.
In comparison, in 2001 households of 2 still remained prevailing with the slight increase to 34%, whilst the second most common number of people per unit became families of 1, accounting for 26% in the following year. Families of 3 people and more experienced a downward trend, decreasing by 3 to 4 percent each. Households of 5 and 6 people, once again, represented the smallest group, accounting for only 6% and 2%.
