Ethnic minorities are set to make up a fifth of the UK population in 40 years, a University of Leeds study predicts.
It says the proportion of black, Asian and other ethnic minorities will rise from 8% of the population, as recorded in the 2001 census, to 20% by 2051.
Researchers say the population will reach nearly 78 million - up from 59 million in 2001.
One of the authors, Professor Philip Rees, said the UK's ethnic make-up was "evolving significantly".
