Local government is a form of public administration which, in a majority of contexts, exists as the lowest tier of administration within a given state.

The term is used to contrast with offices at state level, which are referred to as the central government, national government, or (where appropriate) federal government and also to supranational government which deals with governing institutions between states.

Local governments generally act within powers delegated to them by legislation or directives of the higher level of government.

In federal states, local government generally comprises the third (or sometimes fourth) tier of government, whereas in unitary states, local government usually occupies the second or third tier of government, often with greater powers than higher-level administrative divisions.

An apartment (in American and Canadian English) or a flat (in British English) is a self-contained housing unit (a type of residential real estate) that occupies only part of a building, correctly, on a single level without a stair.

Such a building may be called an apartment building, apartment complex, flat complex, block of flats, tower block, high-rise or, occasionally mansion block (in British English), especially if it consists of many apartments for rent.

In Scotland it is called a block of flats or, if it's a traditional sandstone building, a tenement, which has a pejorative connotation elsewhere.

Apartments may be owned by an owner/occupier, by leasehold tenure or rented by tenants (two types of housing tenure).

An urban area is a human settlement with high population density and infrastructure of built environment.

Urban areas are created through urbanization and are categorized by urban morphology as cities, towns, conurbations or suburbs.

In urbanism, the term contrasts to rural areas such as villages and hamlets and in urban sociology or urban anthropology it contrasts with natural environment.

The creation of early predecessors of urban areas during the urban revolution led to the creation of human civilization with modern urban planning, which along with other human activities such as exploitation of natural resources leads to human impact on the environment.
