The bar chart illustrates the growth in the proportion of individuals living alone across five distinct age categories in the United States over a 150-year period.
Overall, most categories experienced an upward trend over the years. The highest percentage was observed in people aged 55-64 at the end of the period, whereas the lowest figures were recorded in the earliest years.
In 1850, the figures for older people stood at just above 2% and nearly 2.5%, respectively. These 3 categories showed a gradual increase to nearly 2%, 2.5% and just below 4%, respectively, in 1900. Meanwhile, the percentage of people aged 27-36 was introduced at just above 2% in 1900.
Regarding 1950, the percentage of people aged 17-26 emerged at just below 2% in 1950. The first 4 categories (17-26, 27-36, 37-46 and 47-54) rose progressively to just below 2%, and around 2.5%, respectively, in 1950 before rising significantly to 8%, nearly 7.5 and 13%, respectively, at the end of the period. In contrast, despite the oldest category (55-64) was about 9% in 1950, it grew dramatically to nearly 17% in 2000.
