Year-over-year change compares this quarter’s index with the same quarter a year earlier. It is derived by Younivi and is not an official agency series. Latest: 10.29% in Q1 2026.
From Q1 1971 to Q1 2026 (221 quarters): latest 10.29% (Q1 2026); mean 8.11%, median 7.39%; low -7.47% (Q1 2019), high 37.91% (Q1 1989).
Year-over-year change compares a house price index with its value in the same quarter one year earlier: (current index / index four quarters earlier − 1) × 100. Younivi calculates it from the published index. It is a derived percentage, not an official growth series; an agency's own rate can differ because of its methods or rounding.
Use the rate to judge the direction and pace of change over a year. Comparing the same quarter reduces seasonal effects, and percentages can be compared more meaningfully across economies than raw index levels. A negative value means the index is below the same quarter last year; the rate alone does not show when the decline began or how far the index is from its peak.
One year is a short window. Sources can revise past quarters, and a small revision can change the sign of a rate near zero. The result inherits the coverage and method of its underlying index, including any Australian ABS mean-price fallback. It describes a broad trend, not the value of a home or a forecast.
The Australia desk places Australia alongside New Zealand, United States, United Kingdom, Euro area, Korea, Japan, where data are available for the selected measure. It shows the same series as the all-countries desk; the desk only filters the view.
For nominal house prices, the build chooses the longer current OECD or Eurostat series, with the later quarter breaking an equal-span tie. A current UK House Price Index takes precedence for the United Kingdom. Rebased ABS mean dwelling prices are an Australian fallback when the selected index is stale or short, but ABS must itself be current and offer the better eligible history; they are not a quality-adjusted HPI. The real index and price-to-income and price-to-rent measures come from OECD. Younivi derives year-over-year change from the published index. Check the source, licence and date shown on each page.
The chart and table show the same figures. The all-countries chart initially selects the twelve largest latest readings; the legend and filter can change that selection. The country selector changes desks, and range buttons change the visible period without changing the data. The methodology page explains source selection and rebasing.
