How many Waldorf School students are there in the U.S.?

My estimate is around 30,000--about 150 independent schools of approximately 150 each plus another few thousand charter school students. Maybe a few more--if you count homeschoolers, especially--maybe a few less.

Given that there are roughly 50 million K-12 school students in the U.S., that means that about 1/16 of 1 percent are in Waldorf schools of one kind or another. That's a tiny number. To a large, 200 pound person, 1/16 of 1 percent is 2 ounces--a gulp of water, a fish stick. If you make $50,000 per year, 1/16 of 1 percent of that is about $30, barely a tank of gas or a movie night. To put it in further perspective, New York City public schools educate about 1 million students per year, or 33 times as many Waldorf school students as there are in the U.S.
