Europe is aging rapidly, affecting economic growth and public finances. Despite measures such as subsidized childcare and greater gender equality in domestic work, there is no clear solution to increase the birth rate. Immigration remains the main way to counteract the negative effects of population aging. A well-designed immigration system, prioritizing work-based visas and limiting asylum and family reunification visas, can maximize fiscal benefits for Europe. The need for a positive contribution of immigration to government finances is crucial in the face of aging.
