This chart, produced by Visual Economics, shows the average US consumer annual spending by category. The chart is was put together by from survey data gathered by the US Department of Labor. In the large scope the average US consumer unit (which is made up of 2.5 people) spends $49.5K per year, and that housing is the biggest piece of the overall spend, accounting for a little of a 1/3 of every dollar spent. Clicking on the chart it will take you to a larger, more viewable version on the Visual Economics website.
In a similar graphical representation (this one interactive) produced by the New York Times last year, shows greater detail on the consumer spending, and the percentage growth/decline vs. the prior year. Like the graph created by Visual Economics, this also uses data from the US Department of Labor. The graph was done in May of 2008, when the energy crisis was at it worst, and you can clearly see that spending on fuel was up as much as 40% versus the year before. If you click on the chart image below, it will take you to the interactive chart on the New York Times website.
