The given chart shows the proportion of people who do not live with family or friends among five different age categories in the United States from 1850 to 2000.
Overall, it is noticeable that in the past, teenagers lived with their family, while after 1950, more and more young people tended to live by themselves. Additionally, the percentage of people aged from 55 to 64 surviving alone was the highest, while the opposite was true for teenagers.
In 1850, it is clear that only individuals over 37 years old were alive alone, which was around 3% of people in all three age categories. After 10 years, the figure for people from 37 to 64 experienced a slight increase, by 1%, and the percentage of people aged 27-36 existing alone was above 2%.
In 1950, just under 2% of teenagers survived by themselves, while the percentage of people aged 37-54 rose steadily with the growth of their age, at approximately 3,5%, and the proportion of the elderly people staying alone dramatically grew to 9%. In 2000, all the percentage of people in five distinct age categories surviving alone rocketed, at about 5% for teenagers and 8% for people aged 27-36, which was two times lower than the figure of the elderly people, the proportion of two remaining categories was 7% and 13% respectively.
