Population movements of the country have fluctuated over time, in the 19th century with the urbanisation of the country, large amounts of people moved to the capital and the nearby industrial cities, but in recent years there has been a general trend of 'de-urbanisation' as parts of the population have moved back to the countryside. An example of recent large scale internal movement in the 21st century has been the departure of 220,000 White British Londoners to other areas of rural England and Wales over the 2000s and over the 2010s around a total of 550,000 people left the city. Demographically by age, the people leaving the city more than entering tend to be in their 30s and 40s while people entering in their 20s.

In 2010, academic David Coleman produced research postulating a future demographic decline of the White British in Britain, indicating that they would become a minority in Birmingham and London during the 2020s. He also estimated that around 2056 to 2066, the trend of a declining share of the white populace will result in the United Kingdom having an overall white minority. In Prospect, he outlined four projections for a majority-minority scenario within the United Kingdom; If net immigration trends (in 2010) continued its overall trend of 254,000 a year and net emigration of the White British was 74,000 a year (180,000 per year), the White British would decline to 59% of the total population by 2051, 'Other Whites' projected to be at 10% and non-Whites projected to be 31% of the population. By 2066 this would inevitably lead to the White British being a minority of the population. If migration to the United Kingdom was to decline to a net inflow of 80,000 per year, the White British would be 63% of the population by 2051 and would fall below 50% in 2080. Using a cross-party group of MP's recommendation of 'balanced migration', where there is neither a net inflow or outflow, where immigration only consists of 74,000 a year and emigration of the White British the same, the White British would be 67% of the population by 2051 and then
