Intergenerational Economic Mobility among Immigrants’ Children: A Systematic Review and Exploratory Cross-National Synthesis

In the story of a nation's economy, few questions matter more than whether a child's future is written in the stars of their birth or forged by their own efforts. This question lies at the heart of intergenerational economic mobility, a measure of how much a person's income depends on their parents' income. When mobility is high, a child born into poverty has a strong chance of rising to the middle class; when it is low, economic status tends to stick to families like a heavy coat that cannot be shed. For decades, economists have known that countries with wider gaps between the rich and poor tend to have lower mobility, a pattern often called the Great Gatsby Curve. They have also studied how nations welcome newcomers, debating whether to select immigrants based on their skills or to offer them immediate legal security. Yet, until now, no one had systematically connected the specific rules a country sets for immigration to the long-term economic success of the children those immigrants bring.

A new study brings these two worlds together, asking a direct question: do the policies a country uses to manage immigration actually change the economic destiny of immigrant children? The researchers gathered data from thirty-one different studies covering twelve countries over sixty years, creating a massive picture of how immigrant families fare from the 1960s to 2020. They focused on three types of government actions: how a country chooses who gets in, how quickly those people can get permanent legal status, and what kind of support programs exist to help them settle in. By analyzing thousands of data points, the study reveals that while the method of selection matters little, the support provided after arrival is a powerful engine for change.

The researchers found that the most effective tool for helping immigrant children move up the economic ladder is not the points system used to select them, but the settlement programs that help them once they arrive. Countries that invest in publicly funded services—such as language training, help with recognizing foreign degrees, and job placement assistance—see a dramatic drop in the persistence of poverty. In these nations, the economic gap between parents and children shrinks by a significant margin, moving the country from a high-persistence model, where status is largely inherited, to a moderate one where children have a real shot at a different future. This effect is so strong that it can shift a country's mobility profile from resembling the United States to looking more like Denmark.

Interestingly, the study confirms a phenomenon known as the "immigrant advantage." Across the board, children of immigrants show higher economic mobility than the children of native-born parents, even when controlling for other factors. This suggests that immigrant families often possess a unique drive or set of circumstances that propels them forward. However, this advantage is not automatic; it is heavily influenced by the national context. The study shows that in countries with high income inequality, the gap between rich and poor tends to trap families more tightly, making it harder for anyone to move up. Yet, in these same unequal societies, the presence of strong settlement programs makes a particularly large difference, acting as a counterweight to the forces of inequality.

The research also clarifies what does not work as well as many might hope. The specific rules used to select immigrants, such as points-based systems that favor the highly educated, do not appear to significantly change the long-term economic mobility of their children. While these systems bring in parents with high skills, the study suggests that the initial selection is less important for the next generation's success than the environment those families encounter after they land. Similarly, while having a secure legal status is important, its impact is most visible when combined with other supports and in contexts where inequality is high. The data indicates that legal security alone is not a magic bullet, but rather a foundation that works best when paired with active integration efforts.

Ultimately, the study suggests that the debate over immigration often focuses too much on the border and not enough on the arrival. The rules for who gets in are only the beginning of the story. The true test of a nation's integration success lies in what happens next. By investing in the infrastructure of settlement—language classes, credential recognition, and labor market support—countries can significantly alter the economic trajectory of immigrant families. These investments do not just help the first generation; they unlock the potential of the second, ensuring that the children of newcomers are not bound by the circumstances of their parents' arrival but are free to write their own economic futures.
