NCS Respondent Website History

The Bureau of Labor Statistics (BLS) has been in existence since 1884.  Throughout our history, our focus has consistently been on collecting high-quality data on various aspects of the nation’s economy including the conditions of employee compensation.  While the focus and scope of the compensation surveys managed by BLS has changed over time based on legislative direction, emerging trends, and requests received from the data user community, providing information on employee compensation has been a constant in the history of BLS.  In fact, the first BLS study of occupational wages was conducted in 1885 as revealed in the following timeline of compensation studies produced by BLS.
