Mexican Repatriation in the 1930s and the Citizens Sent Away

In October 2005, Governor Arnold Schwarzenegger signed a short bill into law in Sacramento. It did not appropriate money or create a program. It apologized. The Apology Act for the 1930s Mexican Repatriation Program acknowledged that during the Great Depression, state and local governments in California, working alongside federal authorities, had pushed huge numbers of people of Mexican descent out of the country, and that many of those people were United States citizens. The bill was carried by state Senator Joseph Dunn, and behind it stood families who had spent their lives not talking about why parents or grandparents had once been sent to Mexico. An apology seventy years late is easy to dismiss. This one was the first time any government had officially said what happened.

In short: In the early 1930s, federal raids, local relief agencies and public pressure drove several hundred thousand people of Mexican descent, and by some estimates far more, out of the United States, and a large share were American citizens, mostly children. The campaign was presented as voluntary and as a way to save jobs and relief money; it did neither honestly, and its lessons about citizenship, fear and enforcement still apply.

The economy that invited them in

The story begins not with a depression but with a boom. In the 1910s and 1920s, Mexican workers came north in large numbers, driven by the violence of the Mexican Revolution and pulled by American employers. They built and maintained railroads across the West, picked crops in California's valleys, worked in the steel mills of Indiana and the auto plants of Detroit, and filled the packing houses of Chicago. When Congress passed the restrictive Immigration Act of 1924, which imposed tight national-origin quotas on Europe and effectively barred most Asian immigration, it left the Western Hemisphere outside the quota system. Western growers and railroads had lobbied for exactly that. They wanted Mexican labour to remain available.

Many of those workers settled. They married, rented and bought homes, and raised children who were born in the United States and therefore citizens by birth under the Fourteenth Amendment. By the end of the 1920s, Mexican American neighbourhoods were established in Los Angeles, San Antonio, El Paso, Chicago, Detroit and dozens of smaller towns.

Then the stock market crashed in October 1929, and the welcome ended.

Raids, headlines and a park in Los Angeles

As unemployment soared, President Herbert Hoover's administration looked for ways to show it was protecting American jobs. Secretary of Labor William Doak, whose department then oversaw immigration enforcement, launched a deportation drive aimed at people in the country unlawfully. The drive was national, but its weight fell heavily on Mexican communities.

The best-known moment came on February 26, 1931, in Los Angeles, when immigration agents and police surrounded La Placita, the plaza near the city's historic Mexican quarter, and detained hundreds of people in the middle of a weekday afternoon. Only a small number were found deportable. That was not really the point. The raid was publicized beforehand and afterward, and its purpose, as local officials involved in the planning made fairly clear, was to frighten people into leaving on their own.

It worked. A raid that formally deported relatively few people persuaded far more to go, because it announced to every Mexican family in Los Angeles that they were unwelcome and that the authorities would not ask too carefully about who was a citizen.

How "voluntary" removal worked

Federal deportation was only one part of the campaign, and not the largest. The larger part was run by county and city relief agencies, charities and local committees, and it was called repatriation.

Here was the mechanism. A family with an unemployed father applied for relief. Caseworkers suggested, sometimes gently and sometimes not, that the family would be better off in Mexico. The county offered train fare to the border. Los Angeles County organized special trains, and its officials calculated that paying one fare cost less than months of relief payments. Families who declined might find their aid cut off. Families who accepted signed papers they did not always understand, often in English.

On paper, this was voluntary. In practice, it combined economic desperation, official pressure and the background fear created by the raids. Similar programs operated in other places with large Mexican populations, including the industrial Midwest. In Detroit and in the steel towns around Chicago, local welfare offices and employers encouraged and sometimes financed departures.

The language of choice matters, because it is the language governments still use. "Self-deportation," "voluntary departure" and "incentivized return" all describe programs in which the government avoids the costs and legal requirements of formal removal by making staying impossible. The 1930s show what that looks like when it is carried out at scale.

The citizens, mostly children

Estimates of how many people left vary enormously, because no one kept a single count and because "voluntary" departures were recorded inconsistently if at all. Serious estimates range from several hundred thousand to more than a million. Historians Francisco Balderrama and Raymond Rodríguez, whose book on the period helped bring it back into public memory, concluded that a majority of those who left were U.S. citizens.

That figure sounds incredible until you remember the demographics. The adults who had come north in the 1910s and 1920s had, by 1930, many children born on American soil. When a family left, the children left with them. A boy born in Los Angeles in 1922 could find himself, at age nine, in a Mexican village where he did not speak the language well and where he was regarded as a foreigner, carrying a birth certificate that proved he was an American and that no one on either side of the border cared to read.

Some of those children came back as adults, often during the labour shortages of the Second World War, and some served in the U.S. armed forces. Others never returned. Many families simply did not discuss what had happened, out of shame, fear or the sense that no one would believe them. The silence was so complete that by the 1990s, many Mexican Americans had never heard of repatriation, even when it had happened to their own grandparents.

What it did not accomplish

Supporters of the campaign said it would open jobs for citizens and save relief money. Neither claim holds up well.

The jobs argument assumed that departing Mexican workers had been holding positions that unemployed white workers wanted and would fill. Unemployment in the 1930s, however, was not caused by immigrants; it was caused by the collapse of demand across the whole economy, and removing workers did nothing to restore that demand. Many of the jobs vacated were seasonal farm work that went unfilled or was later filled, during the war, by a new guest-worker program that brought Mexican labour back.

The relief argument assumed the families were a drain. But many had been paying rent, buying goods and paying taxes for years, and their children were citizens entitled to whatever help the community provided to anyone. Sending them away removed customers and tenants from neighbourhoods already struggling.

It is worth stating the other side fairly. In the depths of the Depression, local governments faced genuine and desperate fiscal pressure, and some people of Mexican origin did want to go back, especially with the Mexican government encouraging returns and offering land in some cases. Not every departure was coerced. But a policy that pressured citizens to leave their own country, using public relief as leverage, was not made just by the fact that some participants were willing.

The long road to an apology

California's 2005 law did not create reparations. It recognized the wrong and called on the state to remember it. Los Angeles County followed with its own apology in 2012, and a plaque near La Placita now marks the history. No national apology has been issued.

Compare that to the official reckoning with the incarceration of Japanese Americans during the Second World War, which ended in a congressional apology and payments to survivors in 1988. The difference is partly timing: by the time repatriation reentered public memory, most of the people who had been sent away as adults had died. It is partly organization: Japanese American survivors and their children built a sustained campaign. And it is partly that the 1930s removals were dispersed, local and disguised as voluntary, which made them harder to name.

There is a lesson there for anyone who works on these issues now. Harms that are formal, documented and centralized are easier to recognize and remedy later than harms spread across thousands of quiet decisions in relief offices. Writing things down, as they happen, matters.

The thread to the present

The 1930s are not a perfect parallel to today, and it would be careless to pretend otherwise. Modern immigration law is far more detailed, citizens have more legal tools, and the Supreme Court confirmed in Trump v. Barbara in June 2026 that children born in the United States to parents here unlawfully or temporarily are citizens at birth.

But some patterns repeat. Publicized enforcement operations still serve partly to frighten people into leaving. Mixed-status families, in which some members are citizens and some are not, still face the choice of leaving together or splitting apart. And citizens of Latino descent still report being stopped or questioned on the basis of appearance. Our racial justice topic page and immigration and ICE topic page collect current reporting on these questions.

What the 2005 apology asked of Californians was simple: remember that this happened, and remember who it happened to. That is not nothing. A country that forgets it once expelled its own children is more likely to do it again.

Arriving in a country they did not know

The trains from Los Angeles and the Midwest ended at border towns such as Ciudad Juárez and Nogales, and from there families scattered. For the adults who had been born in Mexico, return meant going back to villages and towns they had left years before, often in regions still recovering from revolution and now hit by the same worldwide depression. Work was scarce on both sides of the border.

For the children born in the United States, it meant something stranger. Many spoke English as their first language and Spanish haltingly. They had been to American schools, followed American baseball, and thought of Los Angeles or Detroit as home. In Mexico, some were teased as foreigners. Families who had sold or abandoned what they owned in the United States arrived with little, and promises of land or support in Mexico frequently did not materialize as described.

The Mexican government's role was complicated. Mexican consulates in American cities sometimes helped organize departures, partly out of genuine concern for nationals facing hostility and destitution, and Mexican officials spoke of welcoming their people home. But the government had limited resources to absorb large numbers of returnees in the middle of an economic crisis, and some of the colonization projects announced for them struggled or failed.

Why the story went quiet for so long

For half a century the episode barely appeared in American textbooks. Part of the reason is that it did not look like one event. There was no single order, no single agency and no single list. A raid here, a relief office there, a train chartered by a county, a family that decided after months of pressure that it had no choice: each piece could be described as local, temporary or voluntary.

Part of the reason is the people themselves. Children who had been sent away and later returned often wanted to get on with their lives, and some feared that drawing attention to their past would invite questions about their status, even though they were citizens. Parents carried the shame of having been made to leave. When historians began interviewing survivors in the 1970s and 1980s, many said they had never spoken of it, even to their own children.

That silence is a reminder that historical injustice is not only what governments do but what communities are made to forget.

What you can do

• Learn your local history. If you live in a city with a long Mexican American presence, there is very likely a repatriation story in your local archives. Libraries, universities and historical societies are often eager to collect oral histories while the children of those years, now very old, can still tell them.
• Support organizations that defend mixed-status families. Our directory of nonprofits lists immigrant-rights, civil-rights and legal-aid groups in every state, including those that help citizens prove their status when it is questioned.
• Ask your state legislators what your state has done. California apologized; most states with similar histories have not. Our representatives lookup gives you contact information and recent votes for your state legislators as well as your members of Congress.
• Be precise when you talk about "voluntary" departure. When a program offers families a choice between leaving and losing what they need to survive, say so plainly. That precision is the most useful thing the 1930s can teach.

The people who were sent away did not get a hearing. The least the country can give them now is an accurate account of what was done in its name.
