The bar chart illustrates the proportion of people living solitarily in 5 different age groups in the USA from 1850 to 2000. Overall, the rate of individuals living alone experienced an upward trend and the growth in the figure depended on the age, particularly the older people were, the more likely they lived by themselves.
Upon closer inspection, despite the percentage of 17-to 26-year-old individuals who lived alone, first appearing at nearly 2% in 1950, this figure increased twofold after 50 years. Likewise, although the first appearance of people at 27-36 years old living alone at about 2,2% in 1900, which was lower than 2,3% of 37-to 46 year-old counterparts, the former was 1% higher than the latter at the end of the period.
In terms of remaining age groups, the proportion of residents living solitarily from 47 to 54 years old began at 2,3% in 1850, after which it experienced a significant growth, peaking at nearly 13% after 150 years. The similar pattern can be seen at the percentage of 55-to 64-year-old people living by themselves, at about 3% at the beginning, this figure jumped to 17%, which was the highest rate, compared to other age groups in 2000.
