Politicians and business leaders often refer to small and mid-size quoted companies (SMQCs) as being pivotal to the future of the British economy. But the definition of “small and mid-size” can cover a huge range of companies, and the difference between the UK’s largest companies and the rest is stark, as we present in this paper. SMQC make massive contribution to society and stock market. In particular, we examine the companies quoted on the UK’s public equity markets to highlight the difference in size between the largest 100 companies and the rest.

In particular, we note the following for SMQCs.

• They represent 93% of all the companies quoted on the London Stock Exchange (LSE) by number (when investment companies and certain other categories are excluded – see ‘Our sample’ for more detail).
• They collectively have a market capitalisation of £428bn by value, representing 20% of the total market capitalisation of the LSE (with the same exclusions)[1].
• They employ over 3 million workers.
• They account for a substantial proportion of the workforce of all quoted companies in many regions of the UK.
• They contributed at least £26.5bn in taxes in 2017/18, we estimate, considering just Corporation Tax, Income Tax and National Insurance (NI), and ignoring VAT and Business Rates.
