Shifting Demographics - Experience Summary

Students make observations about the “Nighttime Map” of U.S. population distribution in the year 2000. Then they describe the U.S. population density from 1790 to 2010 based on an animated map. Next they use an interactive demographic map to answer questions about the U.S. population in 2019. Then they use another interactive demographic map to explore a demographic topic of their own choosing. Finally they learn about the purpose of the U.S. census and create a poster encouraging people to respond to the census questionnaire.

Objectives:

  • Analyze the population shift from the Rust Belt to the Sun Belt.
  • Explain the changing population of immigrants in the contemporary United States.

Scene 1 — Engage

Student Activity

Students read an overview of recent demographic changes in the United States and the lesson objectives. They examine contrasting photos of a Sun Belt city (downtown Houston) and a Rust Belt industrial site (abandoned auto body plant in Detroit), then respond to a collaborative wall prompt explaining what they think the terms “Sun Belt” and “Rust Belt” mean based on the images.

Teacher Moves

Use student responses to launch a discussion about regional differences, emphasizing that the photos represent general trends rather than every location in each region. Clarify that students will explore more detailed and objective information about these regions in the next scene.

Scene 2 — Explore

Student Activity

Students examine a map showing the historical shift of the U.S. population center and record the main idea of the map in a table. They then read The Sunbelt and selected sections of A Geographic Overview of the Rust Belt to learn about the recent demographic and economic histories of the two regions, and use a Venn diagram to compare and contrast the Sun Belt and Rust Belt. Finally, they answer multiple-choice questions about the role of air conditioning in Sun Belt growth, the decline of manufacturing in the Rust Belt, and environmental impacts of Sun Belt population growth.

Teacher Moves

Reinforce the key idea that the U.S. population has shifted westward and southward over time. Clarify geographic terms Sun Belt and Rust Belt as needed, and guide students in identifying accurate similarities and differences in their Venn diagrams. Review responses to the multiple-choice questions to check understanding of economic and environmental factors and address any misconceptions.

Scene 3 — Explain

Student Activity

Students read background text on changing immigrant origins to the United States, then use the interactive pie graph in Largest U.S. Immigrant Groups Over Time, 1960–Present to explore shifts in major immigrant groups since 1970 and post a summary of observed trends to a class wall. They read about how immigrants choose where to settle and then use the article Changing Patterns in U.S. Immigration and Population (focusing on the “We Find Four Key Trends” section and its maps) to answer a wall prompt explaining how immigration has influenced population shifts from the Rust Belt to the Sun Belt, citing evidence from the reading and maps.

Teacher Moves

Share and discuss exemplary student summaries of immigration trends, highlighting key shifts such as increased immigration from Latin America and Asia and decreased immigration from Europe. Facilitate a class discussion connecting the four key trends from the article to regional population changes, especially the growth of the Sun Belt and changes in Middle America. Encourage students to reference specific map evidence and, as time allows, point interested students to the additional interactive map on foreign-born residents for further exploration.

Scene 4 — Elaborate

Student Activity

Students read explanatory text about the slowdown and renewed growth of migration to the Sun Belt and then examine The Rise of the U.S. Sun Belt to explore recent economic and demographic trends in that region. They also read The Rust Belt States Are Shaking Off the Dust to learn how Rust Belt states are adapting by attracting new industries. Students post to a collaborative wall describing population trends they observe in their own communities or states and make predictions about future demographic patterns, then respond to at least two classmates with questions or positive comments.

Teacher Moves

Clarify how economic cycles affected migration to the Sun Belt and how both Sun Belt and Rust Belt regions are changing. Decide whether to assign specific articles or allow student choice, and prompt students to connect the readings’ charts and examples to their local observations. Lead a whole-class discussion of students’ posts and predictions, encouraging a range of evidence-based ideas grounded in the sources and students’ experiences.

Scene 5 — Evaluate

Student Activity

Students complete the exit quiz by answering all the questions.

Teacher Moves

Facilitate the assessment and use student data to evaluate understanding, address misconceptions, and identify areas for growth.
