The official data from the Bureau of Economic Analysis say that in February personal spending was down 0.4%, or $40 billion, from the year before. Certainly any drop is bad news, since consumer spending rarely decreases – but $40 billion out of total spending of $10 trillion doesn’t seem like enough to wreak economic havoc.

A closer look, however, shows that Americans have tightened their belts more sharply than the numbers report. The reason? Official figures for personal spending include a lot of categories, such as Medicare outlays, that are not under the control of households. They also include items, such as education spending, that should be treated as investment in the future rather than current consumption.

After removing these spending categories from the data, let’s call what’s left “pocketbook” spending – the money that consumers actually lay out at retailers and other businesses. By this measure, Americans have cut consumption by $200 billion, or 3.1%, over the past year. This explains why the downturn has hit Main Street hard.
