A handful of Black students could trigger near-total white exit from public schools.

Evidence

In South Carolina, where private schools have existed since the 1800s, there were no fully racially integrated private schools before 1954. Some 200 private schools were created between 1963 and 1975; private school enrollment hit a peak of 50,000 in 1978. In Clarendon County, for example, the private academy Clarendon Hall was established in late 1965, after four black students enrolled in a previously all-white public school in the fall term. By 1969, only 281 white students were left in the public school system, and only 16 white students were in public schools when they officially desegregated a year later. — Wikipedia contributors, Segregation Academy, 40
