A quarter is a part of an urban settlement.
A quarter can be administratively defined and its borders officially designated, and it may have its own administrative structure (subordinate to that of the city, town or other urban area). Such a division is particularly common in countries like Bulgaria (Bulgarian: квартал, romanized: kvartal), Croatia (četvrt), France (Quartier), Georgia (კვარტალი, k'vart'ali), Italy (Quartiere), Romania (Cartier), and Serbia (четврт / četvrt). It may be denoted as a borough (in English-speaking countries), Portugal/Brazil (bairro), Spain (barrio); or some other term (e.g. Cambodia (សង្កាត់ sangkat), Germany (Stadtteil), and Poland (dzielnica)).
Quarter can also refer to a non-administrative but distinct neighbourhood with its own character: for example, a slum quarter. It is often used for a district connected with a particular group of people: for instance, some cities are said to have Jewish quarters, diplomatic quarters or Bohemian quarters.
