Area 51 is the common name of a highly classified United States Air Force (USAF) facility located within the Nevada Test and Training Range. A remote detachment administered by Edwards Air Force Base, the facility is officially called Homey Airport (KXTA) or Groom Lake, named after the salt flat situated next to its airfield. Details of the facility's operations are not publicly known, but the USAF says that it is an open training range, and it most likely supports the development and testing of experimental aircraft and weapons systems. The USAF acquired the site in 1955, primarily for flight testing the Lockheed U-2 aircraft.

North America is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere. It can also be described as a northern subcontinent of the Americas.

A metropolitan area or metro is a region consisting of a densely populated urban core and its less-populated surrounding territories under the same administrative division, sharing industry, infrastructure and housing. A metro area usually comprises multiple jurisdictions and municipalities: neighborhoods, townships, boroughs, cities, towns, exurbs, suburbs, counties, districts, states, and even nations like the eurodistricts. As social, economic and political institutions have changed, metropolitan areas have become key economic and political regions.
Population density is a measurement of population per unit area, or exceptionally unit volume; it is a quantity of type number density. It is frequently applied to living organisms, most of the time to humans. It is a key geographical term. In simple terms, population density refers to the number of people living in an area per square kilometre.

An unincorporated area is a region not governed by a local municipal corporation. Similarly, an unincorporated community is a settlement not governed by its own local municipal corporation, but is administered as part of larger administrative divisions, such as a township, parish, borough, county, city, canton, state, province, or country. Occasionally, municipalities dissolve or disincorporate, which may happen if they become fiscally insolvent, and services become the responsibility of a higher administration. Widespread unincorporated communities and areas are a distinguishing feature of the United States and Canada. Most other countries of the world have either no unincorporated areas at all, or these are very rare; typically remote, outlying, sparsely populated, or uninhabited areas.
The North American Central Time Zone (CT) is a time zone in parts of Canada, the United States, Mexico, Central America, some Caribbean Islands, and part of the Eastern Pacific Ocean.
An urban area, or built-up area, is a human settlement with a 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; 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 led to a human impact on the environment. "Agglomeration effects" are in the list of the main consequences of increased rates of firm creation since. This is due to conditions created by a greater level of industrial activity in a given region. However, a favorable environment for human capital development would also be generated simultaneously.
Florida is a state located in the southeastern region of the United States.

The San Francisco Bay Area, popularly referred to as the Bay Area or simply the Bay, is a populous region surrounding the San Francisco, San Pablo, and Suisun Bay estuaries in Northern California.
