Britain has experienced many relatively small episodes of immigration over the
centuries. For nearly a thousand years migration was on a very small scale compared to the size of the population. In the decades between the Second World War and the late 1990s, foreign immigration grew steadily at a relatively modest rate before declining in the late 1960s and becoming fairly stable between 1971 and 1981. The massive increase in the level of migration since the late 1990s is utterly unprecedented in the country’s history, dwarfing the scale of anything that went before. Updated 12 May, 2014
Notes
The Census of 1851 was the first to record those born abroad. The first national census was in 1801.

Iin 1764, for example the Gentleman’s Magazine estimated that there were 20,000 black people living in London alone , while in 1772, another estimate put the number in the whole of England at 15,000. The first scholarly work to deal with Britain’s black population was the 1921 book London Life in the Eighteenth Century, which documented a small but well integrated black population in the Capital. The BBC cite there being 14,000 Black people living in England in 1770. http://news.bbc.co.uk/hi/english/static/in_depth/uk/2002/race/short_history_of_immigration.stm #1500

Folarin Shyllon states that the Black population in the eighteenth century was constantly ‘in flux’ and was quite transient. He states that ‘after weighing these factors, it seems that the black population of Britain throughout the eighteenth century at any given time could not have exceeded 10,000.’ From Black People in Britain 1555-1833 cited in Tessa Hosking Black People in Britain (Macmillan Education, 1984), p.45
Tessa Hosking, says ‘in the 1760s and 1770s estimates were made that varied widely. They ranged from 14,000-30,000 for the whole Kingdom and 14,000-20,000 for London alone.’ Black People in Britain (Macmillan Education, 1984), p.45

Censuses between 1851 and 1931 used a number of categories to record people born abroad. These categories were: those born in British Dominions or Colonies, those who were British subjects by naturalisation, those who were Aliens or had no stated Nationality, those born at sea and those whose birthplace was not stated. For purposes of this report, all the afore mentioned categories have been included in the ‘foreign born’ total. Those born in Ireland have been excluded from the category foreign born. Ireland was part of the United Kingdom until 1921 and we have chosen to exclude those born in Ireland from the foreign born category because of this unique historical connection. All data used in the report is taken from official census records, as provided by the official census upon request. After 1921, only those born in the Republic of Ireland are included.https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/370886/20141106_immigration_rules_introduction_final.pdf
