Summary of changes
Activity on this program started: January 1946
Reference period of change - January 2019
Sampling - All establishments above the thresholds are now selected in the sample as a sample selection of establishments above the thresholds was previously done.
Establishments above the thresholds used to be divided in two strata (one "take-all" and one "take-some"), they are now all put in one "take-all" stratum.
The sample size increase is caused by the change in the sampling design.
