Dorm room

A dormitory (dorm) or hall of residence, is a building primarily providing sleeping and residential quarters for large numbers of people, often boarding school, college or university students. In the United States dorm is the most common term, which comes originally from the Latin word dormitorium. On the other hand, in the United Kingdom the term hall is more usual, especially in a university context. A dormitory can also be a single room containing several beds – see Sleeping dormitories.

Most colleges and universities provide single or multiple occupancy rooms for their students, usually at a cost. These buildings consist of many such rooms, like an apartment building, and the number of rooms varies quite widely from just a few to hundreds. The largest dormitory building is Bancroft Hall at the United States Naval Academy.

Many colleges and universities no longer use the word "dormitory" and staff are now using the term residence hall (analogous to the United Kingdom "hall of residence") or simply "hall" instead. Outside academia however, the word "dorm" or "dormitory" is commonly used without negative connotations. Indeed, the words are used regularly in the marketplace as well as routinely in advertising. College and university residential rooms vary in size, shape, facilities and number of occupants. Typically, a United States residence hall room holds two students with no toilet. This is usually referred to as a "double". Often, residence halls have communal bathroom facilities.

In the United States, residence halls are sometimes segregated by sex, with men living in one group of rooms, and women in another. Some dormitory complexes are single-sex with varying limits on visits by persons of each sex. For example, the University of Notre Dame in Indiana has a long history of Parietals, or mixed visiting hours. Most colleges and universities offer coeducational dorms, where either men or women reside on separate floors but in the same building or where both sexes share a floor but with individual rooms being single-sex. In the early 2000s, dorms that allowed people of opposite sexes to share a room became available in some public universities. Some colleges and university coeducational dormitories also feature coeducational bathrooms.
