The Quarterly Workforce Indicators (QWI) provide local labor market statistics by industry, worker demographics, employer age and size. Unlike statistics tabulated from firm or person-level data, the QWI source data are unique job-level data that link workers to their employers. Because of this link, labor market data in the QWI is available by worker age, sex, educational attainment, and race/ethnicity. This allows for analysis by demographics of a particular local labor market or industry for instance, identifying industries with aging workforces. Links between workers and firms also allow the QWI to identify worker flows – hires, separations, and turnover – as well as net employment growth. As most hiring activity is the consequence of worker turnover rather than employment growth, a focus on employment growth alone may misrepresent employment opportunity in the local labor market. Wages by industry and demographics as well as by whether the worker was newly hired are also available. QWI wages for new hires can be compared to wages for continuing workers, and wage growth for similar workers across industries can be compared to identify important local labor market trends.
