The bar chart represents the proportion of USA citizens living alone in different age groups over one and a half centuries from 1850.
We can observe from the graph that a large number of people from different age groups decided to live alone, especially the people of 55-64 age groups. Furthermore, the figures for all age groups gradually increased over the period.
In 1850, nearly 3% of Americans aged between 55-64 lived alone, followed by 2% of people from 37-46 and 47-54 age groups. However, in 1900, there was a slight increase in the figures of people aged between 47-54 and 37-46. Interestingly, only about 4% of the people aged between 55-64 and 2% of Americans aged between 17-26 started living alone in this period.
In the first 50 years, the increase was minimal, with percentages below 4% for all the age groups. But after 1950, there was a rapid change in the pattern of those living alone. Besides, there was an upward trend in the Americans in the age groups of 37-46, 47-54, and 55-64 with moderate increase to above 7%, 13% and 17% respectively. The Americans aged between 27-36 and 17-26 didn’t start living alone until 1900, but their figures rose from 2% to 5% and 8% in the year 2000.
