Survey of Financial Security (SFS)
Summary of changes
Activity on this program started: 1999
Estimation - In 2005, two new sources of weight adjustments were introduced. The first adjustment was based on administrative data from the T4 file. Weight adjustments were made to ensure that the survey distribution of earnings reflected approximately the same distribution as the T4 population. The second new adjustment made use of Survey of Labour and Income Dynamics (SLID, record number 3889) data to improve estimation. SFS as the smaller sample survey borrowed strength from SLID, the larger sample survey to not only improve SFS estimates but also to bring estimates for the two surveys more in line with each other.
