[10/10/08: See addendum 2, Real Income per Earner...]
[See the addendum at the bottom; added 10/8/08, with new information, and comments about the Obama and McCain campaigns. --Steve]
Rumor has it that middle class incomes stagnated or declined starting around the year 2000. A lot of politicians have been repeating that rumor every chance they get.
Fortunately, however, the rumor is false.
By the way, I've noticed that pundits on the left and right are getting bolder about using the "L" word (..."lie"). The Obama sycophant Keith Olberman asked his idol in a recent interview Why shouldn't it be appropriate just to start calling the opposition's campaign rhetoric "lies." Not to be outdone, McCain supporters flooded the internet with Joe Biden's "fourteen lies" shortly after the VP debate. People are getting less skittish about using the L-word — maybe as a consequence of Al Franken's book from a few years ago.
So, do the mantras about "stagnant middle class incomes" and "only the rich benefited from the economy's growth" deserve a stronger label than just "false rumor"? I don't think so; I think ignorance, belief preservation, and confirmation bias are more likely explanations than dishonesty, so I won't jump on the L-word bandwagon.
I'll begin with a chart of the official numbers that supposedly prove the rumor about the middle class's plight: The "real median household income" from the U.S. Census Bureau (adjusted to 2006 dollars using the CPI-U-RS).
Median household income since 2001 looks stagnant at best, doesn't it? Ouch! Something must have been really wrong with a growing economy that left the median household out of all that growth, don't you think? No wonder we hear so much about it from our politicians.
Hold on though; don't stop thinking just yet — even though many of them would like us to do just that. Try to think of one company — just one, large or small — that has ever written a payroll check to a "household." For example, has Microsoft Corp. ever written a payroll check to "the occupants of the house at 2345 Main Street, Redmond, Washington"?
No, of course not.
A household has a group of people in it; most of those groups contain at least one specific person who earns a paycheck. The U.S. Census Bureau (in their "Current Population Survey") calls those people "Earners." The amount of money income received by a household depends to a great degree on the number of "earners" in that household. (See their household datasets at this page.)
So the question about stagnated incomes is really a multi-part question. Here is the better question, and its multi-part answers:
Did household income stagnate or decline for households with no earners at all? YES. How about for households that had a decline in the number of earners? YES. How about those that had the same number of earners? NO. How about those that had an increase in the number of earners? NO.
By now it should be obvious that an even better question is: Did the middle class income earner participate in the overall economy's growth? It's a better question because it removes the confusion caused by differences in the number of earners per household.
So let's take a look at how "income per earner" did for each of the quintiles of household income. [For reasons I explain in the end note, I had to limit the analysis to 4 out of 5 quintiles, and 9 out of 10 deciles, of household income.]
The chart below shows the result for the period 1994-2007. Note that any possible definition of the "middle class" would show that middle class earners' incomes did not stagnate or decline. In fact, they grew in tandem with the 3.2% average growth rate of overall disposable income per capita (a derivative of GDP).
[This is a corrected chart; the original one contained a math error in the bottom quintile.]
Next is a chart that makes it easier for you to create your own definition of "middle class" if you're so inclined. It's the decile version of household incomes (9 of 10 deciles, to be precise). It won't matter which deciles you pick for "middle class": income per earner grew at pretty much the same rate for all deciles.
Last, we need to address the assertion that "the middle class is disappearing." Sounds like a bad thing, doesn't it: rich get richer, and so forth. So, I asked myself the question, Where is the middle class going? Once again using the Census Bureau's data, I think I figured it out: The middle class of yesteryear is indeed disappearing: it is getting squeezed, like toothpaste from a tube, into the income category labeled "greater than $100,000." Here's a crude movie depicting the squeezing of the middle class — into the unbounded top category of income. (Watch the number of earners in the far-right category grow over time.)
Gee, maybe the "disappearing" middle class of yesteryear isn't such a bad thing after all, huh? Do you think our politicians will be relieved to find out that the rumors about the middle class's stagnation and disappearance are false -- because the historical middle class is simply moving to higher and higher income levels? I hope so, but I won't hold my breath.
The lesson is that economic growth has not benefited only the rich; all classes, however one chooses to define them, have participated. Now all we have to do is get the economy back on a growth track — after we dispose of today's more pressing problem of how to minimize the depth and duration of the recession.
=======================
End note about quintiles and deciles...
The bottom 4 quintiles of household income are easy to analyze, but the 5th (top) quintile is not. The Census Bureau posts forty-one categories of household income; forty of them are $2500 wide, and the last one is of unlimited width. For example, the bottom category is for households with annual money income in the range "0-$2499"; the next one is for the range "$2500-4999", and so on up to the top category, which is labeled "$100000 or more." Each quintile has the same number of households in it (as does each decile), but only four out of five quintiles (or nine out of ten deciles) have easy-to-calculate, weighted-average income per household, and income per earner. That's why the charts don't show the highest one.
Also of interest to some: These income numbers are "money income"; they do not include the value of in-kind transfers, such as food stamps, school lunches, and other programs.
Lastly, my inspiration for diving into the Census Bureau's numbers came from Alan Reynolds's excellent book, Income and Wealth.

Addendum:
Additional information that helps clarify income distribution among household quintiles. Plus, my editorial comments, concluding with thoughts on the Obama and McCain campaigns.
Note the inferences on the two additional charts above. Is it any wonder that making the "household" the basis for evaluating income distribution automatically increases the difference between rich v. middle class v. poor -- as opposed to controlling for earners per household or persons per household?
Said another way: Why should it be a surprise to anyone that a nearly-empty household is likely to have a lower "household income"? Answer: It shouldn't be a surprise. Not only that, it shouldn't be buried as an explanation for the distribution of household income. But that's what is happening.
Oversimplified campaign rhetoric implies that rich households got the benefit of the economy's growth, and non-rich households didn't get any of it; therefore, the market failed us, and we need the government (which we can count on not to fail) to jump in and make the income distribution fairer.
But wait a minute: Did rich workers get all the income growth, while middle class and poor workers stagnated? No, the growth was distributed evenly among those who worked, regardless of their household quintile.
Did full-time workers have higher incomes than part-time workers? Duh. Did full-year workers have higher incomes than part-year workers? Duh. Did two-income households have higher incomes than one-income households? Duh.
Did "failed economic policy" cause all of the difference between household incomes? Absolutely not. Did it cause middle and lower quintiles to "miss out" on the benefits of growth? Absolutely not. Did it cause any difference whatsoever in the way growth was distributed to workers in the five quintiles? Apparently not.
But do we ever hear anything besides "failed economic policy" as the explanation for the income differences among household quintiles? Absolutely not.
Conclusion:
I think we definitely have a fairness issue: we need "fairer" political discourse, instead of oversimplified rhetoric designed to fuel the politically-lucrative class-warfare propaganda machine.
The message should be this:
Our economic record clearly demonstrates that you will get more than your so-called fair share of the nation's economic growth if you get an education, keep educating yourself, work full time, work all year, and stay married -- regardless whether you're rich, middle class, or poor.
But that's not the message we hear, is it? Instead, we hear, "Most of you got screwed by 'trickle down' economics; you should elect me, because I'll see to it that you get your fair share."
Do I expect the Obama campaign to soften the economic class-warfare rhetoric and start talking more sensibly about the successful track record of growth economics? No, not this close to the election; the class warfare message is working too well — because it's simple, and very effective at stirring up emotions. Do I expect the McCain campaign to challenge it? No, I don't think he gets it. Besides, he apparently would rather spew the Concord Coalition balderdash about the national debt, as his campaign descends into the abyss.
My hope is that rational analysis can have a small, positive effect on the Obama administration's approach to growth economics. Let's face it: some of Obama's proposals are supply-side economics, believe it or not. He can't admit it, because that label has already been bastardized for political purposes, but supply side is nonetheless the proper label. I'll explain that in a future article.
There, I've said my piece. My editorial commentary is now finished.

ADDENDUM 2: *REAL* INCOME PER EARNER
The readers have spoken: We need to see real income per earner by quintile and by decile, for an easier comparison with real median household income.
As I said before, the only thing that changes is the Y-axis scale. Adjusting all numbers for the same amount of inflation changes neither the shape of the trend lines nor their relative positions.
Here are the two new charts (quintiles and deciles). All groups shown:
• beat inflation by virtually the same amount, and
• grew at virtually the same rate.
The rich got richer, the middle class got richer, and the poor got richer.
