An excellent interactive view of US Consumer Spending patterns as a percentage of household income over the past 25 years using data taken from the US Bureau of Labor Statistics produced by Flowing Data. With one or two exceptions – spending on clothing as percentage of household income has dropped by almost 50% over this time, the data shows that spending patterns are remarkably stable over this time.
Interesting information and looking forward to the Timetric version: http://flowingdata.com/2009/12/02/past-15-years-of-consumer-spending/
