Recent Census Bureau projections indicate that racial/ethnic minorities will comprise over 50% of the U.S. population by 2042, effectively creating a so-called "majority-minority" nation. Across four experiments, we explore how presenting information about these changing racial demographics influences White Americans' racial attitudes. Results reveal that exposure to the changing demographics evokes the expression of greater explicit and implicit racial bias. Specifically, Whites exposed to the racial demographic shift information preferred interactions/settings with their own ethnic group over minority ethnic groups; expressed more negative attitudes toward Latinos, Blacks, and Asian Americans; and expressed more automatic pro-White/anti-minority bias. Perceived threat to Whites' societal status mediated the effects of the racial shift information on explicit racial attitudes. These results suggest that rather than ushering in a more tolerant future, the increasing diversity of the nation may instead yield intergroup hostility. Implications for intergroup relations and media framing of the racial shift are discussed.
