A fascinating article about What Americans Buy on the NPR website. I found this graphic particularly interesting because the comparison year is the year I was born. Certainly my parents lived in a very small house compared to ours; but then we did too at the age they were then. The changes that are striking are the food vs. housing and apparel vs. transportation. I know it certainly doesn't seem worth it to make clothes like my Mom and I did in the 60s/70s and food is a much smaller part of our budget although rising. My parents never ate out either - a big treat was to go to Steak-n-Shake for burgers once in a while our out for a milkshake.
Check out the article for a discussion of the causes of these changes. How do the percentages compare to your budget?
