Is there a lot of diversity? Are people in Luxembourg City accepting of differences?

"Luxembourg City is a very diverse city, with over 170 nationalities represented in its population. Residents come from the Grand Duchy of Luxembourg, from neighbouring countries, from neighbouring EU countries, and from further away. People are generally accepting of differences in Luxembourg City, since cultural diversity and being open to other cultures has long been part of the country's history," said another expat in Luxembourg City, Luxembourg.
