I love this data essay by some of my @pewresearch.org colleagues looking at how the ways that the U.S. Census has measured race and ethnicity have changed over the country's history and how they're poised to change again in 2030.

How the U.S. government measures race has changed substantially since censuses began in 1790. Today, Americans differ on whether the government should ask about race.
