The bar chart compares how much income Americans earned and how much they spent in 2013 across seven age groups. I would start by saying that both figures increase from youth to middle age and then fall in older groups. In terms of overall patterns, income fluctuates more sharply than expenditure.
First of all, people under 25 and those over 75 spent slightly more than they earned, with income at around 30,000 dollars and spending close to 35,000. One of the aspects I could mention regarding the remaining age groups is that income was consistently higher than expenditure. For instance, Americans aged 25-34 earned in the upper 50,000s while spending in the upper 40,000s.
Furthermore, the highest income levels were recorded among 35-64 year-olds, ranging from roughly 70,000 to 80,000 dollars. Their spending, however, remained more stable, between about 55,000 and 60,000. Another point I would like to mention is that the income-spending gap narrowed again in the 65-74 group.
Finally, the chart shows a clear financial peak in middle age followed by a gradual decline.
