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 compares the proportion of people living alone in five different age groups in the United States from 1850 to 2000.

Overall, it is readily apparent that the proportion of individuals living alone increased in all age groups over the period. In addition, the oldest age group consistently had the highest percentages, whereas the youngest age group remained the lowest.

In 1850, only the three oldest categories were recorded, and all figures were relatively low, ranging from about 2.5% and 3%. By 1900, the 27-36 and 37-46 age groups accounted for just over 2%, while the people aged 47-54 and 55-64 rose to around 3% and 3.5% respectively. In 1950, the percentage of oldest group (55-64) experienced a significant increase to approximately 9%, whereas the other age groups remained below 4%.

By 2000, all age groups experienced substantial growth. Around 5% of those aged 17-26 lived alone, compared with roughly 8% among people aged 27-36. The figures for the 37-46 and 47-54 age groups reached about 7% and 13% respectively, while the highest proportion was recorded by people aged 55-64, at roughly 17%.
