My friend Lizzie Skurnick wades into the NPR discussion about how airtime and sources lean heavily male. Curious, I did some math on my source lists, which turn out to be about two-fifths female in preK-12 and one-third female in higher ed. Certainly if you look at the usual cast of characters commenting on education in the Washington policy world, it is very, very male—and very white. If you have a deep list that includes practitioners and obscure sociology professors, it tends to diversify.
Take a look at your go-to sources, and let me know what you find.
