ABC1, a group of NRS social grades used in the United Kingdom to refer to the middle classes

NRS
The NRS social grades are a system of demographic classification used in the United Kingdom and the Republic of Ireland. They were originally developed by the National Readership Survey in order to classify readers but are now used by many other organisations for wider applications and have become a standard for market research.

Grade Social class Chief Income Earner's Occupation
A upper middle class Higher managerial, administrative or professional.

B middle class Intermediate managerial, administrative or professional
C1 lower middle class Supervisory or clerical and junior managerial, administrative or professional

C2 skilled working class Skilled manual workers

D working class Semi and unskilled manual workers

E underclass Casual or lowest grade workers, pensioners and others who depend on the state for their income

The grades are often grouped into ABC1 and C2DE and these are taken to equate to middle class and working class respectively.
