Drawing again from my own personal experience, I remember using the Survey data in the mid-1970s to calculate the dispersion of earnings among income earners, and its decomposition into the within- and between-sector components, possibly one of the first “official” applications of the exact inequality decomposition proposed by Henry Theil.
15 For a few years, these calculations were published in the chapter on the labour market of the Bank’s Annual Report, integrating the aggregate information on productivity and wage dynamics, and the SHIW main results are still regularly published in the Annual Report.
