During the First World War, the population of Oxford changed.
The number of University members was significantly reduced as students, fellows and staff enlisted.
Some of their places in college accommodation were taken by soldiers in training.
Another reminder of the ongoing war was found in the influx of wounded and disabled soldiers, who were treated in new hospitals housed in buildings such as the university's Examination School, the town hall and Somerville College.

By the early 20th century, there was rapid industrial and population growth, with the printing and publishing industries becoming well established by the 1920s.
In 1929 the boundaries of the city were extended to include the suburbs of Headington, Cowley and Iffley to the east, and Wolvercote to the north.

Also during the 1920s, the economy and society of Oxford underwent a huge transformation as William Morris established Morris Motors Limited to mass-produce cars in Cowley, on the south-eastern edge of the city.
By the early 1970s over 20,000 people worked in Cowley at the huge Morris Motors and Pressed Steel Fisher plants.
Oxford was now a city of two halves: the university city to the west of Magdalen Bridge and the car town to the east.
This led to the witticism that "Oxford is the left bank of Cowley".
Cowley suffered major job losses in the 1980s and 1990s during the decline of British Leyland, but is now producing the successful Mini for BMW on a smaller site.
Much of the original car factories at Cowley was demolished in the 1990s, and is now the site of the Oxford Business Park.

During the Second World War, Oxford was largely ignored by the German air raids during the Blitz, perhaps due to the lack of heavy industry such as steelworks or shipbuilding that would have made it a target, although it was still affected by the rationing and influx of refugees fleeing London and other cities.
The university's colleges served as temporary military barracks and training areas for soldiers before deployment.

On 6 May 1954, Roger Bannister, a 25-year-old medical student, ran the first authenticated sub-four-minute mile at the Iffley Road running track in Oxford.
Although he had previously studied at Oxford University, Bannister was studying at St Mary's Hospital Medical School in London at the time.
He later returned to Oxford University and became Master of Pembroke College.

Oxford's second university, Oxford Brookes University, formerly the Oxford School of Art, then Oxford Polytechnic, based at Headington Hill, was given its charter in 1991 and for ten years has been voted the best new university in the UK.
It was named to honour the school's founding principal, John Henry Brookes.

The influx of migrant labour to the car plants and hospitals, recent immigration from south Asia, and a large student population, have given Oxford a notably cosmopolitan character, especially in the Headington and Cowley Road areas with their many bars, cafes, restaurants, clubs, Asian shops and fast food outlets and the annual Cowley Road Carnival.
Oxford is one of the most diverse small cities in Britain: the most recent population estimates for 2011 showed that 22% of the population were from black or minority ethnic groups, compared to 13% in England.
