How many Catalans are children, grandchildren, or great-grandchildren of immigrants? The data says that 75% –three out of four– are immigrants or have a direct family member, parents or grandparents, who were born outside the country. Catalonia has been, for many decades, in fact, for more than a century, a country that has entrusted its demographic vitality to newcomers. Without them, the collective progress we have experienced would not have been possible. We would be many millions fewer people, we would be poorer, we would be much less dynamic. Of course: the massive incorporation of immigrants in different waves has brought a strong cultural hybridization, a normal phenomenon in advanced societies. Globalization is planetary.
