White flight meant the decrease of non-Hispanic white students in Dallas County K-12 school districts from 1997 until the 2014–2015 school year. The number was 138,760 in the former and 61,538 in the latter; during 2014-2015 county charter schools had about 5,000 non-Hispanic white students. In 2016 Eric Nicholson of the Dallas Observer wrote that the bulk of white K-12 enrollment is shifting to more distant suburban areas beyond Dallas County, and that "Teasing out causation is tricky" but that the perception of poverty, which many white families wish to avoid, is tied with race.
