Buenos Aires is a multicultural city that is home to multiple ethnic and religious groups. Several languages are spoken in the city in addition to Spanish, contributing to its culture as well as to the dialect spoken in the city and in some other parts of the country. This is because since the 19th century, the city, and the country in general, has been a major recipient of millions of immigrants from all over the world, making it a melting pot where several ethnic groups live together. Thus, Buenos Aires is considered one of the most diverse cities of the Americas.
