Madrid, Spain’s capital city, is the country’s largest with about 3 million inhabitants. Of these, at least 17% are immigrants and many Spaniards are from elsewhere. This means that people in Madrid are very friendly to fellow outsiders. If you ask anyone in Madrid about where are they from, you will find hard to find true "madrileño”. Nevertheless, the fact that there are few autochthonous madrileños makes it that much easier for outsiders to feel at home. In short, you don't have to be from Madrid to be a madrileño.
