Employment by Occupation. This spreadsheet is usually published once a year in August and provides a detailed snapshot of employment by occupation, broken down by sex. These estimates are sourced from the Labour Force Survey, a survey of households.
ONS does not recommend comparing these estimates over time as some of the more detailed series can show volatile movements due to the small sample size. Versions of this dataset from 2011 onwards are based on Standard Occupational Classification 2010 (SOC 2010) but earlier versions of the dataset are based on Standard Occupational Classification 2000 (SOC 2000).
