Employment, age 15+ (SA): selected-period comparison
The claim
Employment, age 15+ (SA): different averages either side of Sep 2024
A two-segment mean-shift scan over the last 40 months selects a split in Employment, age 15+ (SA) at Sep 2024: mean 20,565,053 before vs 21,025,756 after (difference = 3.9× pooled variability). The selected date divides two sets of observations; it does not establish when a change began. This descriptive comparison is not a significance test and does not attribute a cause. Window choice and seasonal patterns can affect it.
Method
Descriptive two-segment mean comparison; selects the largest |difference in means| / pooled standard deviation, reported at ratios of at least 1.5 with at least eight observations per segment. No change-date or statistical-significance inference.

| How it is used | Withdrawn — historical record |
| Where it appears | Historical employment selected-period comparison, withdrawn from current use on November 10. The original and maintained earlier readings remain available; a different selected window does not inherit their admission. |
| What would change it | An LFS revision that removes the detected shift, or a reversal returning the level to its prior band across subsequent months. |
| Corrections | 2026-09-14: selected-period comparisons do not establish change dates or statistical significance; calculations are unchanged. |
| Withdrawn | 2026-11-10 |
| Withdrawal reason | The November source successor no longer reproduces this exact admitted candidate. This historical receipt remains available; a different selected window does not inherit admission. |

Receipt wording before withdrawal
Title: Employment, age 15+ (SA): selected-period comparison
Original use state: held
Original destination: The original employment level-shift reading entered the Record on 2026-08-11. Its maintained replacement entered on 2026-09-06 after the new evidence moved the detected breakpoint; the earlier reading remains preserved. This claim is inspectable here but is not separately foregrounded in another public product.
Original trigger: An LFS revision that removes the detected shift, or a reversal returning the level to its prior band across subsequent months.
Original correction note: 2026-09-14: selected-period comparisons do not establish change dates or statistical significance; calculations are unchanged.
