However, due to the booming economy of the city in the late 1980s and early 1990s, Charlotte experienced a rapid immigration from the Northeast and the Midwest, which resulted in a decline of the acceptance of busing. In 1992, in response to these complaints, CMS created a managed choice plan to reduce the number of students being bused. This new choice plan revolved around magnet schools, making one-third of the schools in Charlotte-Mecklenburg either magnets or partial magnets, and each magnet had a quota of black and white students that were allowed to attend. But this didn't please many white families who were denied entrance into magnet schools that had fulfilled their quotas.
