Urban area
large area with high population density and infrastructure of built environment

An urban area, also known as a built-up area or urban agglomeration, is a human settlement with a high population density and an infrastructure of built environment. Urban areas originate through urbanization, and researchers categorize them as cities, towns, conurbations or suburbs. In urbanism, the term "urban area" contrasts to rural areas such as villages and hamlets. In urban sociology or urban anthropology, it often contrasts with natural environment.
The development of earlier predecessors of modern urban areas during the urban revolution of the 4th millennium BC led to the formation of human civilization and ultimately to modern urban planning, which along with other human activities such as exploitation of natural resources has led to a human impact on the environment.
Recent historical growth
In 1950, 764 million people (or about 30 percent of the world's 2.5 billion people) lived in urban areas. In 2009, the number of people living in urban areas (3.42 billion) surpassed the number living in rural areas (3.41 billion), and since then the world has become more urban than rural. By 2014, it was 3.9 billion (or about 53 percent of the world's 7.3 billion people) that lived in urban areas. The change was driven by a combination of increased total population and increased percent of population living in urban areas. This was the first time that the majority of the world's population lived in a city.

Why this record matters
“Urban area” is worth following because a concise public description often conceals a longer documentary argument. Here, Urban, area and large provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 20, 2026. The linked authority identifier is Q702492. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1950, 2009 and 2014.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
