Ethnicity, Race, and Segregation

Active learning helps students move beyond abstract definitions by engaging with real data and contested histories. Mapping, case studies, and structured debate make the geographic and social impacts of ethnicity, race, and segregation visible, concrete, and debatable for learners.

Map Analysis: Redlining Then and Now

Students compare 1930s HOLC redline maps of a US city (Chicago, Detroit, or a city relevant to the class community) with contemporary maps of median household income, life expectancy, or tree canopy coverage for the same area. Working in pairs, they identify spatial correlations and generate claims about how historical policy continues to shape geography. Class discussion addresses causation versus correlation and the policy implications.

Differentiate how the US Census definition of race differs from other countries.

Facilitation Tip

During Map Analysis: Redlining Then and Now, have students annotate maps with both historical and modern census data to track changes over time.

What to look for

Ask students to write one sentence defining ethnicity and one sentence defining race. Then, have them list one specific geographic consequence of redlining in a US city.

Activity 02

• Inquiry Circle
• 55 min · Small Groups

Inquiry Circle: Ethnic Enclaves in the US

Small groups each research one ethnic enclave (Miami's Little Havana, San Francisco's Chinatown, Minneapolis's Somali community, New York's Jackson Heights) and answer: When did this community form? What conditions created it? What economic and social functions does it serve? Has it faced displacement pressure? Groups present findings and the class identifies patterns across different enclave histories.

Analyze the lasting geographic impacts of redlining in American cities.

Facilitation Tip

In Collaborative Investigation: Ethnic Enclaves in the US, assign each group a different city to compare immigration patterns and housing policies.

What to look for

Pose the question: 'How do ethnic enclaves act as both a bridge and a potential barrier for immigrants integrating into a new society?' Facilitate a class discussion where students share examples and perspectives.

Activity 03

• Think-Pair-Share
• 25 min · Pairs

Think-Pair-Share: Race vs. Ethnicity

Students read the current US Census Bureau definitions of race and ethnicity, then work individually to answer: Why does the Census ask these as two separate questions? What are the limitations of these categories? Partners compare responses and the class discusses what political and historical forces shaped these definitions and how they have changed over time.

Explain how ethnic enclaves provide support for new immigrants.

Facilitation Tip

Use Think-Pair-Share: Race vs. Ethnicity to clarify definitions before students analyze census categories or self-identification responses.

What to look for

Provide students with a short excerpt from a US Census Bureau report on race or ethnicity categories. Ask them to identify one way the census definition differs from a common understanding of the term or from another country's approach.

Activity 04

• Structured Academic Controversy
• 50 min · Small Groups

Structured Academic Controversy: Integration Policies

Students evaluate two historical integration interventions -- school busing in Boston and mixed-income housing redevelopment in Chicago's Cabrini-Green -- through competing lenses. Did these policies reduce segregation? Who benefited? Who was harmed? Small groups argue assigned positions before switching sides and working toward a nuanced class position supported by geographic evidence.

Differentiate how the US Census definition of race differs from other countries.

Facilitation Tip

During Structured Academic Controversy: Integration Policies, assign roles to ensure balanced debate and require evidence-based arguments from each side.

What to look for

Ask students to write one sentence defining ethnicity and one sentence defining race. Then, have them list one specific geographic consequence of redlining in a US city.

A few notes on teaching this unit

Start by confronting the myth that segregation is natural or inevitable. Use the redlining maps to show policy as the driver, not individual choice. Avoid framing ethnicity and race as purely cultural topics; connect them directly to land use, economic mobility, and political power. Research shows students grasp social construction best when they see categories changing across time and place, so emphasize historical shifts in Census definitions and legal classifications.

Students will move from recognizing concepts to analyzing their spatial and social consequences, using evidence to challenge common myths. They will connect historical policies to present-day outcomes and articulate how ethnicity and race function differently in American society.

Watch Out for These Misconceptions

• During Map Analysis: Redlining Then and Now, students may claim that residential segregation results from personal housing choices rather than policy.

  Use the side-by-side redlining and contemporary demographic maps to trace specific policy origins (e.g., 1930s HOLC grades, restrictive covenants) and ask students to mark how those boundaries persist in today's racial distribution.

• During Think-Pair-Share: Race vs. Ethnicity, students may assume race is a biological truth with fixed boundaries.

  Provide students with a timeline of U.S. Census racial categories from 1790 to 2020 and ask them to identify which groups were reclassified over time, using this as evidence that race is socially constructed rather than biological.

• During Collaborative Investigation: Ethnic Enclaves in the US, students may interpret enclaves as evidence of immigrant refusal to integrate.

  Have students analyze historical housing ads, deed restrictions, or zoning laws in their case study city to identify structural barriers that led to enclave formation, then discuss how these conditions shape integration choices.
