The changing social class structure of London, 2001–2021: Continued professionalisation or asymmetric polarisation?

The changing class structure of cities has been a topic of considerable importance and debate for over a 150 years, since the industrial revolution created a large industrial proletariat in many western cities. But the rise of post-industrial society, the decline of the manufacturing industry, a shrinking industrial working class, and the growth of the professional and managerial class from the 1970s onwards has provoked fresh debate about this, as has the emergence of gentrification in many cities. This paper looks at the changing social class structure of London from 2001 to 2021 using data from the population Census. It shows that the higher professional and managerial class continued its long term growth after a pause in 2001–2011. But the number and proportions of small employers, the self-employed and routine workers have also grown. There is therefore continuing professionalisation but also ‘asymmetric polarisation’. The paper also examines the geography of social class change by borough over the period and shows that while the professional and managerial class grew in all boroughs, suggesting a gradual upward class change across London, it was highest in the most gentrified inner London boroughs. However, the percentage point growth of the self-employed and routine groups was generally higher in the mostly suburban boroughs where professional and managerial class percentage point change growth was smallest (and vice versa) which suggests an intensified social class sorting and divergence across London with the lower class groups growing most rapidly in suburban outer London where housing costs are less.
