The return to school means, among other things, the return to math class and all the calculations, facts and figures that go with it. Perhaps in anticipation of that, the U.S. Census Bureau’s latest edition of Facts for Features highlights the various statistics associated with the phrase “Back to School.”

According to a recent survey conducted by Parenting.com and Citibank personal finance service Women & Co., much of the money moms spend will go toward their children's clothes. More than 90 percent of the 1,000 moms surveyed indicated they spend more on new outfits for their kids than on clothes for themselves; also, more than half responded they anticipate spending more on clothing this fall than any other kind of back-to-school product.

From clothing shopping to enrollment statistics, from pre-kindergarten to college, here’s a breakdown of school-related numbers across the country from 2009 through 2011.
