white americans are the majority in every census-defined region (northeast, midwest, south, west) and in every state except hawaii, but contribute the highest proportion of the population in the midwestern united states, at 85% per the population estimates program (pep) or 83% per the american community survey (acs). non-hispanic whites make up 79% of the midwest's population, the highest ratio of any region. however, 35% of white americans (whether all white americans or non-hispanic/latino only) live in the south, the most of any region.
