The degree of urbanization in the United Kingdom amounted to 84.88 percent in 2024. This shows almost a three percentage point increase over the past decade. The upward trend, though slow, has been consistently positive. What is urbanization? The rate of urbanization indicates the shift away from rural living as people come together in densely populated cities. The United Kingdom is much more urban than the worldwide average. This puts people in closer proximity to jobs, health care, stores, and social opportunities, leading to better economic, health, and social outcomes. For example, areas with higher urbanization have a higher average life expectancy at birth. The darker side of urbanization London is the United Kingdom’s largest city and arguably the financial capital of Europe. However, this economic success has led to increasingly high rental prices, which is an indication of the high cost of living in the city. The higher population density can also lead in an increase in crime. London has one of the highest homicide rates in England and Wales. In spite of these drawbacks, London continues to draw millions of overseas tourists every year.

The urban areas geography consists of major urban agglomerations, cities, and smaller towns defined in terms of their physical extent rather than by any administrative boundaries Source: Census 2001 / Office of the Deputy Prime Minister (ODPM) Publisher: Nomis Geographic coverage: England and Wales Time coverage: 2001 Notes: Urban areas have been defined starting with the Office of the Deputy Prime Minister's areas of urban land use - areas in England and Wales of at least 20 hectares in extent identified using a tangible bricks-and-mortar approach. Major urban areas and others with more than one central focus are divided where possible to produce figures about localities within them. Previously separate urban areas, where urban land has merged, are also recognised by subdivisions where possible. Subdivisions often follow the boundaries of local authorities existing before reorganisation in 1974, or the boundaries of current authorities within urban areas.
