Linda Brown was a third grader in Topeka, Kansas, when her father, Oliver Brown, tried to enroll her in the white public school four blocks from her home. Otherwise, she would have had to walk across railroad tracks to take a bus to attend the nearest all-Black one.

When she was denied admission, Oliver Brown sued.

The case, and four others from Delaware, the District of Columbia, South Carolina and Virginia were combined and made their way to the Supreme Court. All of them involved school children required to attend all-Black schools that were of lower quality than schools for white children.

While the Supreme Court found in 1954 in Oliver Brown’s favor, years would pass before desegregation  of American schools began in earnest. And for many Black students now, 70 years since the nation’s highest court held unanimously that separate is inherently unequal, educational resources and access remain woefully uneven.

Here are some of the racial realities of American public education today:

25: That’s the percentage increase in Black-white school segregation between 1991 and 2019, according to an analysis of 533 districts by sociologists Sean Reardon at Stanford University and Ann Owens at the University of Southern California. While school segregation fell dramatically beginning in 1968 with a series of court orders, it began to tick up in the early 1990s because of the expiration of court orders mandating integration, school choice policies, and other factors. Still, schools remain significantly less segregated than they did before and immediately after the Brown decision.

10: That’s the proportion of Black students learning in a school where more than 90 percent of their classmates were also Black, according to 2022 Department of Education data. That figure is down from 23 percent in 2000. Even as Black-white school segregation has increased slightly since the early 1990s, the number of extremely segregated schools has shrunk, in part because of an increase in the Hispanic student population. Meanwhile, from 2000 to 2022, the percentage of white students attending a school that is 90 percent or more white fell from 44 percent to 14 percent.

6: This is the percentage of teachers in American public schools who are Black. By comparison, Black students make up about 15 percent of public school enrollment. One legacy of Brown v. Boardis the dearth of  Black teachers: More than 38,000 Black educators lost their jobs after the decision came down, as white administrators of integrating schools refused to hire Black professionals for teaching roles or pushed them out. Yet research suggests that more Black teachers in the classroom can help boost Black student outcomes such as college enrollment.

2014: That’s the year that Wilcox County High School, in rural Georgia, held its first school-sponsored, racially integrated prom. After desegregation, parents in the community, like many across the South, began organizing private, off-site proms to keep the events exclusively white. That practice persisted in Wilcox County until 2013, when high schoolers organized a prom for both white and Black students. The next year, the school made it official, finally holding an integrated event.

$14,385: This is the average amount spent per Black pupil in public school, compared with $14,263 per white student, according to a 2022 analysis of 2017-18 data by the Federal Reserve Bank of St. Louis. The researchers found that while school district spending was very similar for Black and white students, the sources of funding differed somewhat, with Black students receiving more federal funding and white students receiving more local funding. The amount of money spent on instruction per pupil, meanwhile, was slightly lower for Black students – $7,169 – than for white students ($7,329). The researchers attributed that to a number of small, predominantly white districts that spent far above average on their students.

7: That’s the share of incoming students at the University of Mississippi who were Black in 2022 — even though nearly half the state’s public high school graduates, 48 percent, were Black that year. That gap between Black students graduating from high school in Mississippi and those enrolling at the state flagship university has grown over the past decade, according to a Hechinger analysis. Similar trends are playing out elsewhere in the country: In 2022, 16 state flagship universities had a gap of 10 percentage points or more between Black high school graduates and incoming freshmen. And at two dozen flagships, the gap for Black students stayed the same or grew between 2019 and 2022. Yet public flagships were created to educate the residents of their states, and most make that explicit.

Revisiting Brown, 70 years later

The Hechinger Report takes a look at the decision that was intended to end segregation in public schools in an exploration of what has, and hasn’t, changed since school segregation was declared illegal.

700: That’s roughly how many high schools are offering the College Board’s Advanced Placement African American Studies course this school year, more than 10 times as many that offered it a year earlier, when it debuted. The course was created in part in response to longstanding concerns that African American history has been downplayed or left out of K-12 curriculum. But the A.P. course, an elective, became ensnared in politics. The content has evolved after criticism that it introduced students to “divisive concepts,” among other reasons; it has been banned or restricted in some states. Nevertheless, about 13,000 students are enrolled in this second year of the pilot course, which took more than 10 years to develop. Forty-five percent of students taking the class had never previously taken another AP course, which can earn them college credit.
