To ensure that the LFS reflects current labour market conditions as accurately as possible, data are revised following each census to reflect the most recently available population estimates, geographic boundaries, and industry and occupation classifications. This standard revision process results in minor changes to recent and historical LFS data and has little impact on trends in key labour market indicators, such as employment, unemployment, and labour force participation rates. Revised LFS data series for the period from 1987 to 2024 were released on January 24, 2025. For more information on the details of the revisions, please see The 2025 Revisions of the Labour Force Survey (LFS). 

Disability Labour Market Indicators data have also been revised to reflect the most recently available population estimates and geographic boundaries. 

Summary of changes

• Control totals used in the calibration of the DLMI weights have been updated to use Census 2021 projections.
• Census metropolitan areas (CMAs) used in the calibration of the DLMI weights are now based on the Standard Geographical Classification (SGC) 2021.
• These updates impact the DLMI weights and bootstrap weights for all records starting in 2022, as calibration of the DLMI weights uses the number of households in a given geographical area.
