When migration is in the news, it is often cast in negative terms, but it has many benefits for host countries, from economic growth to critical support for systems like Social Security that support aging populations. That's according to a new report produced by two Fletcher School professors and four graduate students for the Club de Madrid, an international group of former heads of states that is concerned with policy issues worldwide.

The publication, "Overcoming Misinformation About Migration and Migrants: A Data-Driven Report on the Positive Impact of Migration on Economy and Social Development," addresses a number of issues in detail, showing, above all, that migration is not a black-and-white issue, and deserves a more nuanced approach.

The report came about thanks to a connection made by Carlos Alvarado-Quesada, professor of the practice of diplomacy at The Fletcher School and former president of Costa Rica. The Club de Madrid wanted a report on the economic and political aspects of migration, and he suggested a collaboration between the organization and the Henry J. Leir Institute for Migration and Human Security at Fletcher.

The Club de Madrid defined the policy areas to be examined, and the Fletcher team—Alvarado-Quesada, Leir Institute Director Katrina Burgess, a professor of political economy at Fletcher, and graduate students Lorenzo Beadle, Joaquín Martínez Albán, Lauren Davis, and Govind Harish—did the research and wrote the report.

"So much of the discourse around migration is about security and the threat posed by migration, and the Club de Madrid was very interested in producing some empirically grounded narratives," says Burgess.

A primary question was whether the data show that migrants are a threat to receiving countries.

"In fact, it turns out it's the opposite in many cases," says Burgess. "But it's complicated. Obviously, there are times when migration creates real challenges, but on balance, it's more of an opportunity than a threat."
