De facto segregation is the separation of racial, ethnic, or economic groups that happens in practice (through housing markets, lending discrimination, and residential choices) rather than by law, producing segregated neighborhoods and unequal access to services in cities.
De facto segregation means "segregation in fact." No law forces groups to live apart, but they end up separated anyway because of market processes, discrimination, and social patterns. In U.S. cities, the big drivers were redlining (banks refusing or limiting loans in minority neighborhoods), blockbusting (real estate agents scaring white homeowners into selling cheap), white flight to the suburbs, and plain affordability gaps. The result looks a lot like legal segregation on a map, even though no statute requires it.
The AP CED puts this under the social challenges of urban change (EK SPS-6.A.1): housing discrimination, unequal access to services, environmental injustice, and the growth of disamenity zones. The geographic punchline is that de facto segregation is sticky. Even after fair housing laws banned discrimination on paper, the spatial patterns those practices created kept reproducing themselves through property values, school funding, and where people could afford to buy.
This term lives in Topic 6.10, Challenges of Urban Changes (Unit 6) and supports learning objective 6.10.A: explain causes and effects of geographic change within urban areas. De facto segregation is the effect that ties together the causes the CED lists, redlining, blockbusting, and housing affordability. It also sets up the responses the CED covers, like inclusionary zoning and urban renewal. Beyond Unit 6, it's a classic example of how spatial patterns outlast the policies that created them, which is exactly the kind of process-to-pattern reasoning AP Human Geography rewards.

Redlining (Unit 6)
Redlining is the mechanism; de facto segregation is the result. When banks systematically denied mortgages in minority neighborhoods, they locked residents out of homeownership and locked the segregated pattern in place for decades.
White Flight (Unit 6)
White flight moved white, middle-class residents (and their tax dollars) to the suburbs, leaving behind underfunded inner-city neighborhoods. No law made anyone move, which is what makes the resulting segregation de facto.
Gentrification (Unit 6)
Gentrification can flip de facto segregation rather than fix it. Wealthier newcomers raise rents and displace longtime low-income residents, resorting the city by class and often by race, just in a new direction.
Housing Affordability (Unit 6)
Even with zero discrimination, big income gaps between groups sort people into different neighborhoods through price alone. Affordability is why de facto segregation persists long after discriminatory laws and lending practices are banned.
Multiple-choice questions love the de jure vs. de facto comparison, asking why residential segregation persisted in U.S. cities after legal segregation ended. You'll also see data-based stems, like mortgage denial rates of 18% in majority-minority neighborhoods versus 4% elsewhere, where you need to name the process (redlining producing de facto segregation). Map-comparison questions show city residential maps from, say, 1970 and 2020 and ask why segregation persisted despite the 1968 Fair Housing Act. On FRQs, this concept supports questions about inner-city decline, suburbanization, and urban renewal, like the 2017 FRQ on cities counteracting decline after deindustrialization. Your job is to connect a cause (discriminatory practice or market process) to a spatial effect (segregated neighborhoods, unequal services).
De jure segregation is separation required by law (think legally mandated separate schools or neighborhoods). De facto segregation happens without any law, through lending discrimination, housing prices, and residential choices. The exam tests whether you understand that ending de jure segregation did not end de facto segregation; banning the laws didn't undo the housing patterns, wealth gaps, and lending practices that kept groups spatially separated.
De facto segregation is separation that exists in practice through markets and social behavior, not because any law requires it.
In the U.S., it was produced by redlining, blockbusting, white flight, and affordability gaps, all listed in EK SPS-6.A.1 as challenges of urban change.
De facto segregation persisted after fair housing laws like the 1968 Fair Housing Act because the spatial and economic patterns were already locked in.
Segregated neighborhoods lead to unequal access to services, environmental injustice, and disamenity zones, the downstream effects the CED expects you to explain.
Responses like inclusionary zoning try to break the cycle by requiring affordable units in new development.
On the exam, always connect a specific process (like redlining) to the spatial pattern it produced; naming "segregation" alone isn't enough.
It's the separation of groups in space that happens through housing markets, lending discrimination, and residential choices rather than by law. It shows up in Topic 6.10 as a social challenge of urban change, tied to redlining, blockbusting, and housing affordability.
De jure segregation is required by law; de facto segregation happens in practice without any law. The exam's favorite angle is that de facto segregation persisted in U.S. cities even after de jure segregation was outlawed.
No. The 1968 Fair Housing Act banned discriminatory practices like redlining on paper, but residential maps of cities like Chicago and Milwaukee show segregation persisting into the 2020s because affordability gaps, property values, and informal discrimination kept reproducing the old patterns.
The main drivers tested on the AP exam are redlining (discriminatory mortgage lending), blockbusting, white flight to the suburbs, and housing affordability gaps. Each one sorts people into different neighborhoods without any law requiring it.
Yes. It falls under learning objective 6.10.A in Unit 6, and it shows up in multiple-choice questions using mortgage denial data or residential maps from different decades, asking you to explain why segregation persisted after legal segregation ended.
