Economics and the Great Migration
Lesson 3:

The Origins of Wealth Inequality in America
Lesson Author
Brett Burkey, Florida Council on Economic Education

Standards and Benchmarks (see page 3.15)
Lesson Description
The economic collapse of the 1930s caused the U.S. government to develop new policies to put
Americans back on their feet again. Many of these programs centered on growing the housing
stock and providing tools for households to begin generating wealth. Discrimination did not
allow for Black Americans to have an equal opportunity at building a middle-class lifestyle—the
bedrock of the American Dream. These inequities began an ever-widening wealth gap that has
impacted generations far removed from the original policies.

Materials
•

PowerPoint slide deck for “Economics and the Great Migration Lesson 3: The Origins of
Wealth Inequality in America”

•

Handouts 3-1, 3-2, and 3-3, one copy of each for each student

Preparation
This lesson includes activities that you can distribute digitally or as hard copies. A redlining
activity requires accessing the redlining map site (see Procedure step 7), so students can use
in-class devices, or the teacher can project the maps in the classroom. You can preview the maps
at https://lojic.maps.arcgis.com/apps/MapSeries/index.html?appid=e4d29907953c4094a17cb9ea8f8f89de.

Procedure
1.

Tell the students they will explore historical reasons for the wealth gap that exists today between
White and Black American households. To aid in their understanding, the class will work through a
set of slides that provide the background. Distribute one copy of Handout 3-1: The Origins of Wealth
Inequality in America Graphic Organizer to each student and indicate that the slides and notes
pages are set up to work in unison. The organizer will help the students collate all the important
terms, policies, and data.

2.

Display Slide 2 of the PowerPoint slide deck for “Economics and the Great Migration Lesson 3:
The Origins of Wealth Inequality in America.” Explain that a major housing shortage existed during
the depths of the Depression and that much of the housing stock lacked many of the basic
conveniences, such as plumbing and electricity.

3.

Display Slide 3. Explain that the Roosevelt Administration signed the National Housing Act on
June 27, 1934. This established the U.S. Department of Housing and Urban Development (HUD)

and the Federal Housing Administration (FHA). The FHA was created to facilitate home financing,
improve housing standards, and increase employment in the home-construction industry. Policies
such as “redlining” prevented these opportunities from being shared with Black American households. Explain that the FHA’s primary function was to insure home mortgage loans made by banks
and other private lenders, thereby encouraging them to make more loans to prospective home
buyers. But the FHA systematically excluded the mortgages of Black American home buyers.
4.

Display Slide 4. Explain that the FHA feared property values would fall if people of different races
resided in the same neighborhood. This would make the mortgage loans riskier and make it more
difficult for the lenders. The image on the slide is the actual language from the FHA Underwriting
Manual.

5.

Display Slide 5. Explain that Homer Hoyt was influential in standardizing the mortgage lending
process. One of his innovations was to rank home buyers’ “desirability” based on criteria including
national origin, religion, and race. This became the model upon which the Home Owners’ Loan
Corporation (HOLC) created a series of maps. Initially, the HOLC was established under the Federal
Home Loan Bank Board (FHLBB). In 1939 it was transferred to the FHA. The HOLC made loans.
The FHA did not make loans; it insured them.

6.

Display Slide 6. Explain that these maps were called “Residential Security” maps, which document
how loan officers, appraisers, and real estate professionals evaluated mortgage lending risk. The
most-desirable areas are shown as green, and the least-desirable areas are shown as red. They
came to be known as redlining maps because the “unworthy” neighborhoods were circled and
highlighted in red.

7.

Display Slide 7. Tell the students they will now explore a redlining map and the observations
that appraisers used to color-code the city of Louisville, KY. Distribute a copy of Handout 3-2:
Redlining Louisville, KY: Compounding Poverty to each student (either digitally or hard copy).
Instruct students to access the map online at https://lojic.maps.arcgis.com/apps/MapSeries/
index.html?appid=e4d29907953c4094a17cb9ea8f8f89de to complete the assignment (link also
embedded in the slide). Read the instructions with the students to help them understand how
to manipulate the maps. Show them how to access and enlarge the thumbnail pictures of the
assessments. Click on the tabs at the top to access the overlay maps, and slide the vertical bar
to illustrate the comparisons. Once students are comfortable navigating the page, tell them to
write down their observations on Handout 3-2. Discuss the following:
•

Questions 1-3: Answers will vary, as each student is asked to choose features they believe were
integral to the policy decisions.

•

Question 4: The eastern region of the community seems to have the highest concentration of
wealth. Most of those communities were designated blue and green risk levels.

3.3

Economics and the Great Migration | Lesson 3: The Origins of Wealth Inequality in America

•

Question 5: In each case it’s the western region of the map that has the highest concentration
of Black households.

•

Question 6: It appears the western region of the map was the area deemed most risky in the
1930s, based on the number of redlined neighborhoods. In those areas, it was unlikely a household could take advantage of the generous mortgage conditions the FHA was offering. Today,
the highest concentration of low-income and Black households is in the western region of Greater
Louisville. Black families’ inability to purchase homes and begin building wealth in past eras
has led to huge obstacles for many families in building generational wealth and equity through
real estate.

•

How did the deliberate denial of financing in the early and mid-twentieth century affect
the finances of many Black Americans? (Answers may include the following: Black citizens
were unable to purchase homes; they were unable to build the wealth that comes from homeownership; they were often forced to pay inflated housing prices because housing options were
limited for Black families; or they were unable to build a credit portfolio, which led to higher
costs for Black American households in all their financial pursuits.)

•

What similarities did you notice between the 1937 redlining map and the maps generated
from the most-recent U.S. Census on race, income, and poverty? (The areas that were redlined
are also areas that are communities of color with pockets of low-income households today.)

8.

Display Slide 8. Point out that discrimination is defined as the unjust or prejudicial treatment of
different categories of people, especially on the grounds of race, age, or sex. Explain that residential developers received the mortgage insurance they desired by including and enforcing
racial barriers in the language of their property deeds. Many White families migrating to new
suburban developments wanted assurances that their communities would bar integration.
Three examples are shown in the slide.

9.

Display Slide 9. Explain that the validity of these restrictions was upheld by the U.S. Supreme
Court in 1926. According to the decision, the equal protections provided under the 14th Amend­
ment did not apply in what was perceived to be private circumstances. Developers used the
decision as a marketing enticement shortly after it was released. Shelley v. Kraemer in 1948
made these covenants unenforceable by courts.

10. Display Slide 10. Explain that Baltimore was one of the first cities to embrace these barriers and
that the mayor at the time expressed his commitment to erecting these barriers citywide.
11. Display Slide 11. Explain that the extent to which communities would go to fight integration
was displayed in this case against the Bradens. In addition to the violence community members
directed toward the Wades, the courts took the unusual path of charging Carl Braden with a
Communist plot.

3.4

Economics and the Great Migration | Lesson 3: The Origins of Wealth Inequality in America

12. Display Slide 12. Explain that in Detroit, not only was it necessary for the developer to include
racial covenants in the property deeds, but the FHA demanded that this wall be erected so that
Black residents could not walk through the all-White neighborhood. This wall remains standing
in its original spot today as a marker of uncivil times.
13. Display Slide 13. Explain that Levittown is considered one of the first modern suburbs that has
shaped so much of American life today. The developer embedded strong barriers to maintain
the homogeneity of the community. Though racial covenants were finally outlawed by the Fair
Housing Act of 1968, America’s suburbs remain predominantly White today: According to the
Pew Research Center, 90% of suburban counties have a majority-White population.1 Show the
students a video of a CBS News segment at https://www.youtube.com/watch?v=YXYA0tSebOA&t=22s (link also embedded in the slide). The video reports on the restrictive history of the
community in New Jersey where the news journalist grew up. It expresses the surprise so many
people face when they realize their hometowns have a history of such bias. After students watch
the video, tell them to answer the assessment questions included in the graphic organizer.
Discuss the following:
•

Can you suggest a way in which the financial injustices of the past can be rectified today to
narrow the wealth gap? (Answers will vary, but the suggestion in the clip is that some form of
financial compensation or reparation be offered to Black Americans to make up for the wealth
they couldn’t accumulate because of discriminatory policies.)

14. Display Slide 14. Explain that the chart indicates the significant disparity in homeowning rates
that exists today between races. The inability to establish a wealth stream in the twentieth century
has created challenges for contemporary Black American households to purchase homes at today’s
prices.
15. Display Slide 15. Explain that generational wealth has accelerated the gap between White and
Black households. A current income gap exists, but it pales in comparison to the differences in
net worth or wealth. Net worth or wealth is the value of a person’s or family’s assets minus their
liabilities. For many people or families, net worth comes mainly from their home value, so appreciating housing prices increase wealth.2 Equity is the sum of the home buyer’s initial down payment
and the difference between the debt owed and the current appraised value of that home. Give
the following example: If you buy a $300,000 home and put 20% down, you immediately have
$60,000 in equity. Ten years later, you’ll still owe $150,000 on the loan, but the market appraises
your home to be worth $400,000, so that’s $250,000 of additional equity. That equity represents
a major portion of most people’s wealth.

Economics and the Great Migration | Lesson 3: The Origins of Wealth Inequality in America

16. Display Slide 16 and explain that due to this lingering disparity, many Black American families
have been unable to find for themselves or provide their children with opportunities that would
lead to greater achievements or wealth creation. The costs of college, elder care, and a satisfying retirement have been placed beyond the reach of so many because of the discriminatory
policies in the past.

Closure
17. Review the main points of the lesson by discussing the following:
•

On what belief were so many housing policies based? (Answers will vary but may include the
belief that the presence of Black Americans as homeowners in a neighborhood would cause
property values to fall and make mortgages riskier.)

•

What is redlining? (It’s a term used to describe the way in which loan officers, appraisers, and
real estate professionals evaluated mortgage lending risk. It was a process that resulted in
color-­coded neighborhoods; the most-desirable areas were colored green on a map, and the
least-desirable areas were colored red.)

•

What were three features that frequently led to appraisers coloring sections of the HOLC
maps red? (Answers will vary but may include a high percentage of Black families, a high percentage of working-class people, a large number of rental properties, or undesirable land
conditions like the tendency to flood, proximity to industrial areas, and great distance from
transportation hubs.)

•

Why did developers use the Corrigan v. Buckley decision as a feature in their advertising?
(It sent the message that no non-Caucasians would be moving in next door.)

•

What is the single largest facet of household wealth for the majority of Americans? (Answers
will vary but may include the equity in one’s home, which is equal to the assessed value of the
home minus any debt associated with the purchase of the home, or the skyrocketing values of
real estate, which has generated great wealth for some.)

•

How did government policies lead to the wealth gap between White and Black households?
(Government policies made it extremely difficult for Black citizens to purchase homes. For most
families, building wealth hinges on the ability to profit in the real estate market. The denial to
Black families in the mid-twentieth century of this key financial tool has compromised the financial foundation for generations of Black Americans.)

Assessment
18. Provide a copy of Handout 3-3: Assessment to each student. Allow time for students to work and
then review the answers as follows:
1.

How did this map guide the lending practices of banks and developers when considering
access to mortgages?
The maps made it simple for lenders to know where borrowers who fit within FHA criteria of
creditworthiness were located, as well as borrowers that the FHA deemed unfit for credit. For
developers, the maps made it clear where the FHA would support the development of communities and where it would not. For all, the red areas especially were off limits because no underwriting support would be offered, and the lender would need to shoulder all the risk.

2.

What were the typical features of a green section of the map? Red section?
Green sections of the map were generally areas where affluent households resided, comprising
professionals and white-collar workers. There was a high level of homeownership, and the
properties would enjoy many amenities. The communities would be exclusively White families
and generally of the Protestant faith. The appraisers would award the highest level of optimism to
continued appreciation of home values in the green sections.

3.

This map was published and released in 1937, so why would families be concerned about
its implications today?
The 1937 maps provide a startling foretelling of the status these communities would hold in
contemporary times. The green areas from 1937 are typically still the most affluent parts of
communities where an overwhelmingly White population resides. The red areas of 1937 are the
places today where you would still find the highest levels of poverty and distressed properties.
Black and immigrant families would not have had the opportunity to build wealth, so their
descendants likely still reside there. Early investment in the green areas allowed them to thrive
today. Meanwhile, the lack of capital investment in the red areas relegated them to perpetual
erosion.

4.

What are three things that wealth allows people to do for their families that were often out
of reach for Black families?
When one’s ancestors have the opportunity to generate net worth or wealth for their families, it
often provides the basis for current and continued development of wealth. It allows new generations to stand on the shoulders of past generations and provides the means to further grow
the wealth generated. Having that wealth allows families to bequeath it to future generations
for continued progression. Wealth allows families to send their children to college, care for their
elderly, and save for a comfortable retirement. It gives people the means to purchase property,
start businesses, and purchase equities. Wealth gives people freedom to pursue their passions
and live a fuller life. It gives people the means to look after each other when ill health strikes.
So, while no guarantee, wealth can contribute to greater longevity. The lack of wealth can place
these benefits out of reach.

Questions

The FHA was willing to insure lenders from loan default, taking the risk out of mortgages for the bank or
developer. This made them very willing to lend to home buyers.

Handout 3-2: Redlining Louisville, KY: Compounding Poverty (page 1 of 3)
Directions: Interpret a map the Home Owners’ Loan Corporation (HOLC) developed in the 1930s that
housing developers used to guide residential investment in the city of Louisville. This map assigned
grades “A” through “D” to neighborhoods to indicate their desirability for investment. Black, immigrant,
and low-income neighborhoods were often given grades of “C” or “D,” eliminating residents’ access
to mortgage insurance or credit for decades. Compare the HOLC map with maps that show current
demographic features of the same neighborhoods in Louisville to see how little has changed. Make the
connection between policies of the past and financial status of households today. Access the maps at
https://lojic.maps.arcgis.com/apps/MapSeries/index.html?appid=e4d29907953c4094a17cb9ea8f8f89de.

the highest concentration of wealth? Now slide the bar to reveal the redlining map. What color(s)
were most of those communities designated for risk level?

5.

Click on the “Compare Race” tab. What region of the metropolitan area seems to have the highest
concentration of Black households? Now slide the bar to reveal the redlining map. Based on what
you know about the criteria used to zone neighborhoods for risk, what region of the metropolitan
area had the highest concentration of Black households at that time?

6.

You have compared the HOLC redlining map with the current U.S. Census maps for race, income,
and poverty in Louisville. Now propose a correlation between the FHA risk assessments and
decisions to deny mortgages to Black families during the 1930s-50s and the level of wealth and
prosperity Black families (in general) have today in Louisville.
