In 1968, The Kerner Commission predicted U.S. cities would have negro majority by 1985
FYI
It became true, all large cities had negroid majority by 1983 - the same year a change was made to dilute negro majority by including rural white populated areas plus the large city's population, even if the outer areas were located in other surrounding counties. By doing this, it consistently keeps whites as the majority population in the U.S. This method became known as metropolitan statistical area (MSA)
Since 1983 large cities were no longer enumerated as the actual population of the city
