In 1931, 9.4% of Wigan's population was middle class compared with 14% in England and Wales, and by 1971, this had increased to 12.4% compared with 24% nationally. Parallel to this slight increase in the middle classes of Wigan was the decline of the working class population. In 1931, 38.7% were working class compared with 36% in England and Wales; by 1971, this had decreased to 33.5% in Wigan and 26% nationwide. The rest of the population was made up of clerical workers and skilled manual workers or other miscellaneous. The slow decrease in the working class goes against the trend for a steeper national decline, reinforcing the perception of Wigan as a working-class town.
