Four years ago, I wrote an op-ed for the Washington Post revealing that DC spent nearly $25,000 per pupil during the 2007-08 school year. I calculated this figure from the public budget documents of the District of Columbia, which I subsequently summarized and linked on this blog.

No education reporter followed up on my findings, and much lower per pupil figures continue to be reported to this day. My $25,000 figure was even greeted with skepticism by analysts at free market think tanks. One state education policy analyst wrote to say that my figure was “out of line with credible information,” and that I gave my critics “too much ammunition with this clearly questionable set of statistics.”

Indeed, the Census Bureau figures for DC’s total K‑12 expenditures were substantially lower than mine. I made a note to track down the discrepancy, but other projects intervened. When I updated my calculation to use DC budget estimates for the 2008-09 school year, I found that District spending had risen to over $28,000 / pupil. The comparable number for that year reported by the Bureau of the Census was just $18,181 (which you get by dividing the total expenditure figure in Table 1 by the enrollment figure in Table 15).

So you can see why most folks were skeptical. Skeptical, but wrong.

Back in March of this year I asked my then research intern to contact the Census Bureau and ask where they got their total spending data. It turns out, they got them from a DCPS official. We presented evidence to the Bureau that that DCPS official had missed a few line items when completing the Census Bureau’s forms—to the tune of about $400 million. The Census Bureau agreed and is in the process of obtaining corrected data for the 2008-09 year. In the meantime, they made sure to ask DC officials to include all relevant items when filling out their forms for the 2009-10 school year. The result: Census Bureau data now show DC spent a total of $29,409 per pupil (obtained by dividing total expenditures in Table 1 by enrollment in Table 15). This is just a bit higher than my calculation for the preceding year.

Kudos to the Census Bureau for taking the initiative and getting DC to accurately report its public school expenditures. Now that education reporters can simply open a Census Bureau .pdf file and divide one number by another, I wonder if any will report what DC really spends per pupil? I suspect that they still will not, continuing to mislead the general public, but I would be delighted to be proven wrong.

Oh, and, BTW, this spending figure is about triple what the DC voucher program spends per pupil—and the voucher students have a much higher graduation rate and perform as well or better academically.
