Today, one in seven new marriages -- 14.6 percent -- unites spouses of different races, according to the Pew Research Center. The interracial marriage rate has doubled since 1980, and is six times what it was in 1960. For some combinations, the rate of increase has been even more rapid. When Barack Obama was born in 1961, less than one new marriage in 1,000 was, like his parents', that of a black person and a white person. "By 1980, that share had risen to about one in 150 new marriages," Pew notes. "By 2008, it had risen to one in 60."

Although Obama identified himself simply as "black" in the census enumeration last year, a swelling cohort of younger Americans refuses to be so easily pigeonholed. The Census Bureau currently recognizes 63 possible racial labels, but that taxonomy is as limited and artificial as the one in an earlier age that sorted Americans into the categories of "white," "Japanese," "Chinese," "Negroes," "mulattoes," "quadroons," "octoroons," and "civilized Indians." By what logic, for example, did the 2010 questionnaire classify Korean, Chinese, and Vietnamese as separate races, yet lump Scandinavians, Arabs, and Slavs together as "white"? With so many millions of Americans dating, marrying, and loving across the color line, and with the population of blended Americans exploding, isn't it clearer than ever that the pressure to keep sorting ourselves into races that have no objective genetic meaning anyway is incoherent and counterproductive?

Yet instead of shutting down the racial bean-counters, the government is giving them new powers. The Times reports that new Department of Education rules require any student who acknowledges any Hispanic ethnicity at all to be reported solely as "Hispanic" in federal filings. That doesn't sit well with López-Mullins, whose Peruvian-Chinese-Irish-Shawnee-Cherokee family tree is considerably more diverse and interesting than the word "Hispanic" alone can possibly convey.

To be sure, some lobbies and grievance groups profit handsomely from aggravating racial distinctions. But most Americans have moved beyond the color-consciousness of generations past, and it's time federal agencies did too. Congress ought to instruct the Census Bureau to stop counting Americans by race, and to mark the occasion by installing at its headquarters a great monument bearing these words, which Thurgood Marshall wrote for the NAACP Legal Defense Fund in the 1950 Supreme Court case of McLaurin v. Oklahoma:

"Racial criteria are irrational, irrelevant, [and] odious to our way of life."
