The Supreme Court Today Upheld the Validity of the 1990

The Supreme Court today upheld the validity of the 1990 census, ruling unanimously that the federal government had no constitutional obligation to adjust the results to correct an acknowledged undercount in big cities and among minorities . . . . At the core of the legal challenge to the 1990 census was the racially disparate undercount, the existence of which no one disputed. The census missed about 2 percent of the population as a whole, some four million people. But it missed 4.8 percent of the Black population and 5.2 percent of the Hispanic population. - The New York Times, 3/21/1996
