A new study reveals that wealthy nations within the Organisation for Economic Co-operation and Development (OECD) have experienced significant economic benefits from immigration over the past 35 years. The research, to be presented at the European Central Bank Forum, indicates that increased immigration correlates with growth in both productivity and GDP per worker. Specifically, a 1% increase in a country’s immigrant population is linked to a 1.2% rise in GDP per worker within five years, and 1.9% within ten. This finding is particularly relevant for countries like those in the European Union, where native population growth has been declining since 2015 and accelerated during the COVID-19 pandemic. The study challenges claims that immigration negatively impacts economies, highlighting the positive effect of skilled immigrant labor. Researchers found that increased investment is a key driver of this economic growth, despite rising political tensions surrounding immigration in several nations.
