In modern times, Arab Christians have played important roles in the Nahda movement, and they have significantly influenced and contributed to the fields of literature, politics, business, philosophy, music, theatre and cinema, medicine, and science. Today Arab Christians still play important roles in the Arab world, and are relatively wealthy, well educated, and politically moderate. Emigrants from Arab Christian communities also make up a significant proportion of the Middle Eastern diaspora, with sizable population concentrations across the Americas, most notably in Brazil, Argentina, Venezuela, Colombia, and the US. However, those emigrants to the Americas, especially from the first wave of emigration, have often not passed the Arabic language to their descendants, having integrated into the majority-Christian communities to which they emigrated.
