This file contains the digital vector boundaries for Major Towns and Cities in England and Wales in 2015. The Major Towns and Cities (TCITY) statistical geography provides a precise definition of the major towns and cities in England and Wales. The geography has been developed specifically for the production and analysis of statistics, and is based on the Built-Up Areas geography that was created for the release of 2011 Census data. 112 TCITY are included in the dataset. The TCITY boundaries are generalised and created using an automated approach based on a 50m grid squares.

Among selected cities in the United Kingdom, Birmingham received the highest score in the Clean Cities ranking of space for walking and cycling in 2022 at a score of 38 percent followed closely by Manchester with a score of 34 percent. London and Edinburgh also made the list of selected European cities ranked by space for people and received a score of 32 percent and 31 percent, respectively.

How would you define the boundaries of a town or city in England and Wales in 2016?

Maybe your definition would be based on its population size, geographic extent or where the industry and services are located. This was a question the ONS had to consider when creating a new statistical geography called Towns and Cities.

In reality, the ability to delimit the boundaries of a city or town is difficult!

Major Towns and Cities

The new statistical geography, Towns and Cities has been created based on population size and the extent of the built environment. It contains 112 towns and cities in England and Wales, where the residential and/or workday population > 75,000 people at the 2011 Census. It has been constructed using the existing Built-Up Area boundary set produced by Ordnance Survey in 2011.

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.
