Birmingham's 2023 population is now estimated at 2,665,100. In 1950, the population of Birmingham was 2,228,915. Birmingham has grown by 19,502 in the last year, which represents a 0.74% annual change. These population estimates and projections come from the latest revision of the UN World Urbanization Prospects. These estimates represent the Urban agglomeration of Birmingham, which typically includes Birmingham's population in addition to adjacent suburban areas.
The Census of 2011 shows that Birmingham's population had reached 1,137,100.
Birmingham's city proper covers 267 square kilometers, with a population just over 1 million. The entire metropolitan area covers 598 square kilometers and boasts a population of 4,332,629 individuals. The population density overall comes to approximately 4,200 people per square kilometer.
For most of its history, Birmingham saw steady population growth as it grew into one of Britain's most important industrial centers. It's most significant period of growth was between 1911 and 1921 when the number of people living in the city almost doubled. In just ten years, the population increased from 525,833 to 919,333, a growth rate of 74.9%.
Since then, however, Birmingham's population has gone up and down. The 2011 census marks the third time that the city's size has exceeded one million people. The milestone was reached for the first time in 1931 when the population was recorded at 1,002,603, but the following census from 1939 marked a fall to 995,039. The city bounced back to 1.1 million residents in 1951, but by the time of the 2001 census, it's population had fallen again to 977,087. Birmingham's council is no doubt crossing its fingers in the hope that they will once again be able to join London as the only British city with a population of over a million.
Birmingham is even more ethnically diverse than London, the country's capital city. The 2001 census confirmed that 70.4% of the people of Birmingham were white, 19.5% were Asian, 6.1% were Black, 0.5 were Chinese, 2.5% were mixed race, and 0.6 were of another ethnic group.
Birmingham is also notable for having the UK's highest Gypsy and Traveller population. At 53,554, more than 5% of the people living in Birmingham are Gypsies or Travellers.
Christianity remains the city's most prominent religion. In the last (2001) census 59.1% of Birmingham residents reported themselves as being Christian. Other major religions were Islam (14.3%), Sikh (2.93%), and Hindu (1.98%). 12.4% of the surveyed population reported having no religion, and 8.4% did not answer the question.
