Between 1968 and 1989, children born to parents of different races increased from 1% of total births to 3.4%. For Black and White parents, births increased from 8,700 in 1968 to 45,000 in 1989. There has also been an increase in biths to Japanese and White parents. There are now 39% more births to Japanese-White parents than births to Japanese-Japanese parents (in the U.S.). By 1989, for every 100 births in which both parents were Japanese, there were 139 births where the parents were mixed. Between 1968 and 1989, Chinese-White births more than tripled (from 1,000 to over 3,800). --Futurist May-June 1993 p.54-55
From 1970 to 1991, the number of mixed-race married couples increased from 310,000 to 994,000. This trend is taking place among all racial and ethnic groups, but with differing patterns for each group. --Futurist May-June 1993 p.54-55
