The provided bar chart illustrates the percentage of US single-person households across five age cohorts from 1850 to 2000. Overall, an upward trend was observed across all age groups over time. While the older groups experienced the most significant increase and remained the highest, the figures for younger people remained comparatively lower until 2000.
In 1850, 47-56 and 37-46 age groups showed similar data at slightly above 2%. The percentages for those aged 17-26 and 27-36 were comparable, both holding unrecorded figures. By contrast, the 55-64 group witnessed the highest proportion, at approximately 3%. Fifty years later, despite a slight increase to nearly 3.5%, the figure for this age group remained the highest among all groups. Meanwhile, the proportion of those aged 47-54 experienced a similar rise by about 0.5 percentage points, while the figures for the 17-26 and 37-46 groups remained unchanged. In contrast, the 27-36 group showed a significant upward trend, rising to around 2.3%.
After five decades, the proportion of people aged 55-64 living alone doubled to around 9%, making it the highest figure. Conversely, the 27-36, 37-46 and 47-54 age group saw only a slight rise of about 0.2 percentage points. Meanwhile, the figure for those aged 17-26 rose modestly to nearly 2%. By 2000, all age groups experienced significant growth, with the figures roughly doubling to reach approximately 5%, 8%, 7%, 13% and 17%, respectively.
