Population pyramid of Slough by ethnicity in 2021

The following table shows the ethnic group of respondents in the 1991, 2001 and 2011 censuses in Slough. Slough is a majority-minority town, with no ethnic group or broad multi-ethnic group being the majority, having been this way since the late 2000s. The White British make up the largest group at 34.5% of the population, having declined from a majority status of 58.3% in 2001, this decline coincides with the overall decline of White residents in the town from nearly two thirds in 1991 (72.3%) to less the majority (45.7%) in 2011. In conjunction, Asian British people have risen from nearly a quarter of the town's population in 1991 (23.9%) to nearly 40% in 2011, the largest of which is British Pakistanis who surpassed British Indians in 2011 as the largest Asian group. Black British residents have also increased, with the majority of growth coming from Black Africans who have increased from 0.4% in 1991 to 5.4% in 2011, of which surpassed the Black Caribbean group, who was 2.2% of the population, in 2011 as well.

Ethnicity of school pupils

Since statistics on the ethnicity of school pupils have been collected, White students, the majority being the native White British, have been in the minority. As such Slough schools were in a majority-minority state in-till 2018 when Asian British pupils became the majority, of which had surpassed White students in the mid-2000s. In the Asian British multi-ethnic group, British Pakistanis are the largest at 25.8% and are the largest group of all groups in the town. Black British school pupils increased in proportional size between 2004 and 2012 peaking at 9.1%, but have declined since then to 7.2% in 2022. Mixed school pupils have also been in proportional increase and now make up a little over 1 in 10 in schools (11.3%) from 5.9% in 2004.
