Foreign born in London in 1961 mapped in London boroughs
Note:
Caution should be applied as certain districts themselves (especially in East London) cannot be recreated exactly to the boundaries they exist in today. This notice applies to: Barking and Dagenham, Newham, Waltham Forest, Redbridge, Wandsworth, Southwark and Lambeth.
A small degree of data is missing from the 1961 census itself (1% rough, exact numerical amount of 17 data slots out of a total of 765, this may have a more pro-nounced effect on the data for certain districts), please refer to NOMIS's 1961 Census User Guide for more information.
Own work, data taken from 1961 census on Residents born outside UK by country of birth figures (which was recreated using 1961 district to match London's modern boroughs) then divided against total population of each borough using A Vision of Britain through Time. NOTE: There are statistical clarifications for this file, please check the description for information.
