Band 9: The chart shows the percentage of individuals living alone across five distinet age categories in the United States from 1850 to 2000. Provide an overview of the information by identifying and describing the key details, and include comparisons where appropriate.

The bar chart illustrates the percentage of people living alone in the United States across five age groups during the period between 1850 and 2000.

Overall, the proportion of individuals increased over time in every age category. While the figures were relatively low and fairly similar in the nineteenth and early twentieth centuries, a much more noticeable rise occurred after 1950, particularly among the two oldest age groups.

In 1850, the percentages were modest, ranging from around 2.5% among those aged 17-26, 37-46 and 47-54 to approximately 3% for the 55-64 age group. By 1900, all age groups experienced only slight growth. The highest figure was recorded for people aged 55-64, at just over 3%, whereas the remaining categories stood at roughly 2-3%.

A more significant upward trend can be seen from 1950 onwards. The proportion of 17-26-year-olds living alone was still relatively low, at about 2%, while the figures for the 27-36, 37-46 and 47-54 groups were all close to 3-4%. In contrast, the percentage for those aged 55-64 rose sharply to around 9%, making it by far the largest group.

By 2000, the gap between the oldest and youngest age groups had widened considerably. Around 5% of people aged 17-26 lived alone, compared with approximately 8% of those aged 27-36 and 47-54, and about 7% of the 37-46 group. The highest proportion was once again among 55-64-year-olds, reaching roughly 17%, almost double the figure recorded in 1950.
