New-home price inflation: selected-period comparison
The claim
New housing price index, % y/y: different averages either side of Jul 2025
A two-segment mean-shift scan over the last 40 months selects a split in New housing price index, % y/y at Jul 2025: mean -0.39 before vs -2.05 after (difference = 4.2× 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.
