It may seem like it’s still summer — it’s hot and many people are on vacation. But one of the nation’s largest seasonal events is already under way. It’s back to school time. From nursery school to college, 77 million students are headed to the classroom — that’s more than one-out-of-four of the total U.S. population aged 3 and over. Of the 56 million elementary and high school students enrolled this fall, 11 percent will attend private schools. There are almost 99,000 public schools across the nation, along with nearly 34,000 private schools. Getting ready for school this month means buying a lot of new clothes — nearly $7.5 billion worth.
