Immigration grew initially for the lucrative inland and Great Lakes connected fur trade, based on continuing relations with influential Native American chiefs and interpreters.
After Detroit rebuilt in the early 19th century, a thriving community soon sprang up, and by the Civil War, over 45,000 people were living in the city,[23] primarily spread along Jefferson Avenue to the east and Fort Street to the west.
In addition to attracting the best workers in Detroit, Ford's high wage policy effectively stopped the massive turnover rate, raised productivity, lowered overall labor costs and helped to propel the Model T to industry dominance.
At this time, the hardships of life in the Jim Crow South and the promise of manufacturing jobs in the North brought African Americans to Detroit in large numbers in the Great Migration.
Supported by Detroit's business, professional, and Protestant religious communities, the League campaigned for a new city charter, an anti-saloon ordinance, and the open shop whereby a worker could get a job even if he did not belong to a labor union.
Although many people began to pile into Detroit, Thomas Sugrue, author of "The Origins of the Urban Crisis", suggests, "Beginning in the 1920s—and certainly by the 1940s—class and race became more important than ethnicity as a guide to the city's residential geography."
It expanded its borders exponentially by annexing all or part of the incorporated villages of Woodmere (1905), Delray (1905), Fairview (1907), St. Clair Heights (1918), and Warrendale (1925), as well as thousands of acres of land in the surrounding townships.

Highly controversial was his using eminent domain to purchase and raze a 465-acre inner-city neighborhood known as Poletown that was home to 3,500 people, mostly Polish property owners, in order to make way for a half-billion-dollar General Motors Cadillac assembly plant.
The closed auto plants were also often abandoned in a period before strong environmental regulation, causing the sites to become so-called "brownfields", unattractive to potential replacement businesses because of the pollution hangover from decades of industrial production.
[125] The mass migration of hopeful blacks from the Jim Crow-perpetuated racism and segregation of the South into Northern neighborhoods coupled with sluggish housing construction flooded Detroit with overpopulation, limited funding, and residential mistreatment.
In particular, the Federal Housing Administration (FHA) and the Home Owners Loan Corporation (HOLC) effectively marked the racial boundaries of Detroit to determine the actuarial soundness of urban neighborhoods.
[132] By preventing black from the ability to attain mortgage loans from local banks, the New Deal private-public partnerships used redlining to protect the property values and investment opportunities for white middle-class homes.
Colorblind universalism within Detroit's housing market remained a far-fetched aspiration of Black families in their pursuit of homeownership as FHA-HUD policy failed to dismantle the segregative impulses of the real estate industry.

The Oakland-Hastings Freeway, now called the I-375 Chrysler Highway, was laid directly along Hastings Street at the heart of the Black Bottom business district, and cut through the Lower East Side and Paradise Valley.
[160] In the aftermath of the riot, the Greater Detroit Board of Commerce launched a campaign to find jobs for ten thousand "previously unemployable" persons, a preponderant number of whom were black.

[232] Most CLTs are not built upon economically self-sustaining models, so they are forced to compete for external funding, taking away the CLT's autonomy, as all of the power is transferred into the hands of grant-funding organizations and private foundations.
