The Warmth of Other Suns: The Epic Story of America's Great Migration

The summary

Six million people left, and the country barely wrote it down. Between roughly 1915 and 1970, that many Black Americans walked away from the South for the North, the Midwest and the West, in a movement with no founding date and, for most of the twentieth century, no settled name. Isabel Wilkerson’s argument is that this was one of the great population shifts in American history, that the people who made it were immigrants in everything but the legal definition, and that missing this has warped the way Americans explain their own cities ever since.

The outline is a matter of record. Around 1900 roughly nine in ten African Americans lived in the South; by 1970, according to the Smithsonian’s National Museum of African American History and Culture, that share had fallen to about 53 percent. It moved in two waves — the first toward New York, Philadelphia, Chicago and Detroit around the First World War, the second running west after the Second, to Los Angeles, Seattle and Portland. Wilkerson gave fifteen years to the book and interviewed more than 1,200 people. Then she narrowed it to three.

An immigration nobody filed as one

Her framing is deliberately provocative. She calls the Great Migration a defection as much as a migration, and describes the people who made it as seeking political asylum from a caste system inside the borders of their own country. That is the load-bearing claim, and the rest of the book tests it. Immigrants leave a place that will not have them, travel at cost and risk, cluster on arrival, take the work available, and get blamed for the condition of the neighborhoods they are confined to. Every part of that pattern shows up here — except that these travelers never crossed a border, so the country filed them as a domestic problem rather than as a wave of arrivals.

The routes make the point. People did not scatter at random. They followed the rail lines, which is why Mississippi emptied into Chicago, Florida into New York, and Louisiana and Texas into Los Angeles. A movement with that much structure is not a drift. It is a decision, made six million times.

The sociology had the causation backwards

For decades the received story was that southern migrants brought their troubles with them and broke the northern cities — a reading often hung on Daniel Patrick Moynihan’s 1965 Labor Department report, whose fourth chapter was titled “The Tangle of Pathology.” Wilkerson’s case is that this reverses cause and effect, and she leans on demographers to make it. The sociologist Stewart Tolnay found that the migrants had more schooling than the southern Black population they left behind — the leavers, not the stayers. That edge was real but modest: Tolnay found they had less schooling than northern-born Black residents, and both gaps narrowed over the century.

What met them was not opportunity but containment. She describes a family named Clark moving into Cicero, Illinois, and a mob ransacking the apartment, throwing their belongings out the windows, and eventually burning the building down. Restricted to a few blocks, charged more rent for worse housing, shut out of the better work — that, on her reading, is where northern urban poverty actually came from. The migrants did not import it. They were sorted into it on arrival, and then held responsible for it.

What the leaving cost

Three lives carry all of this, and none of them is a clean escape story.

Ida Mae Brandon Gladney, a sharecropper’s wife, left Mississippi for Chicago in 1937 after her husband’s cousin was beaten nearly to death over a theft he had not committed. In Chicago her husband hauled ice up four and five flights of stairs before she found steady work as a hospital aide. George Swanson Starling was a strong student pulled out of school and into the citrus groves around Eustis, Florida; he began pressing the growers for better pay, and fled for his life in 1945, spending the rest of it working the railroads that carried other people north. Robert Joseph Pershing Foster left Monroe, Louisiana in 1953 and drove west across the desert alone because no motel along the way would take him. He became a Los Angeles surgeon whose patients came to include Ray Charles.

The North charged its own price. Wilkerson notes that Black residents already established in those cities often resented the new arrivals, the way settled immigrants close the door behind them. And the historical record thinned by choice: some who left never spoke of the South to their children, out of embarrassment or a refusal to look back, much as immigrant parents sometimes decline to pass on the old language. A movement she reckons larger than the Gold Rush went partly unrecorded because the people who made it preferred not to discuss it.

They remade the culture regardless. Wilkerson counts Toni Morrison, Miles Davis, Aretha Franklin, August Wilson, Prince and Tupac Shakur among the children of the Great Migration — artists whose work, she argues, is unreadable without it. The title itself comes from a passage in Richard Wright’s Black Boy, written by a man who had made the same trip out of Mississippi.

The bottom line

The Great Migration was an immigration story the United States declined to recognize as one, and Wilkerson’s central correction concerns blame: the people who left were, by the research she cites, more ambitious and better educated than the story told about them, and the poverty later pinned on them was largely built around them after they arrived. Six million private decisions, taken without anyone calling for them, reshaped American cities and American culture.

Read it if you want the twentieth century to make more sense than it currently does. Pair it with Caste, where Wilkerson gives a name to the system these three were running from.
