THE PROJECTIONS ARE BASED ON BUREAU OF THE CENSUS UNPUBLISHED POPULATION PROJECTIONS BY COLOR AND ON THE ASSUMPTIONS THAT PAST TRENDS IN LABOR FORCE PARTICIPATION RATES WILL CONTINUE, THAT THE SIZE OF THE ARMED FORCES WILL NOT CHANGE SIGNIFICANTLY, AND THAT THE ECONOMY WILL OPERATE AT RELATIVELY HIGH LEVELS CONSISTENT WITH AN UNEMPLOYMENT RATE OF ABOUT 4 PERCENT. RECOGNIZING THE UNCERTAINTY OF THE PROJECTIONS, IT IS ESTIMATED THAT BETWEEN 1965 AND 1980 -- (1) THE TOTAL NONWHITE LABOR FORCE WILL HAVE RISEN BY 41 PERCENT COMPARED WITH ONLY A 28 PERCENT INCREASE IN WHITE WORKERS, (2) THE NUMBER OF NONWHITE WORKERS WILL INCREASE FROM 8.7 MILLION TO 12.3 MILLION WHILE WHITES WILL INCREASE FROM 69.7 MILLION TO 89.1 MILLION, (3) THE EXPECTED GROWTH OF THE TOTAL POPULATION ACCOUNTS FOR 86 PERCENT OF THE PROJECTED LABOR FORCE INCREASE, (4) THE NUMBER OF YOUNG, AGES 14 TO 24, NONWHITE WORKERS WILL INCREASE BY NEARLY 30 PERCENT AND YOUNG WHITE WORKERS BY 20 PERCENT, AND (5) AMONG WORKERS AGED 25 TO 54, THE NUMBER OF WHITE WOMEN WILL INCREASE BY ABOUT 31 PERCENT, NONWHITE BY 27 PERCENT, NONWHITE MEN BY 3 PERCENT, AND WHITE MEN WILL NOT INCREASE.
