Methodology & Data Sources
Last updated: April 2026
METROX aggregates publicly available data from multiple sources to compute market indicators, price benchmarks, and the Demand Index. This page documents where the data comes from, how often it is refreshed, and what limitations apply.
1. Data sources
METROX builds market indicators from aggregated public market signals — published market reports, public and institutional statistics, public news and editorial coverage, search-interest and web-activity data, advertising indicators, official statistical anchors, industry research, and open government and geospatial data — processed through proprietary AI-powered models that infer, normalize, and statistically aggregate district-level signals. METROX is not a reseller or partner of any specific listing platform, ad platform, news outlet, or data vendor. METROX does not expose or redistribute listing-level records, seller contacts, listing text, photos or source-provider inventory. The dashboard displays aggregated district-level indicators and METROX-calculated scores only. The exact mix and weighting of inputs evolves as our models improve.
2. Refresh cadence
District-level metrics (price, yield, Demand Index) are recomputed several times per week. Official anchors (OeNB, Statistik Austria) are ingested quarterly. The “as of” date shown on the dashboard reflects the most recent snapshot.
3. How we compute the numbers
Per district, METROX computes a robust central tendency of asking-price benchmarks (median per m² — the standard used by international real-estate indices). Citywide aggregates are activity-weighted across district medians, so districts where the market is more active contribute proportionally more. Pre-live historical anchors are calibrated to public quarterly indices and cross-checked against industry research so the time series joins smoothly. The METROX Demand Index is a proprietary composite score from 0 to 100 based on aggregated public market signals, search-interest indicators, advertising indicators, macro context, published market research and METROX estimates. Yields are gross estimates and exclude individual ownership costs.
4. Limitations — asking prices vs transaction prices
All METROX prices are asking-price benchmarks — not realized transaction prices, not official Mietspiegel, not existing rental contracts. Empirical research (Levy Institute 2024; Berlin School of Economics 2025) shows asking prices typically exceed transaction prices by 5–15%, with the gap widening for premium and new-build segments. Asking-price benchmarks are most useful as leading indicators of seller expectations and short-term market direction (the methodology used by Rightmove in the UK), and for district-level granularity unavailable in transaction-based public indices. For exact transaction-level valuations, consult the Statistik Austria HPI or commercial valuation databases (IMMOunited, PriceHubble). Districts with limited published market coverage may show short-term volatility. All figures are non-binding estimates and do not replace individual valuation or professional advice.
5. Beta status
METROX is in public beta. Features, data sources, and calculation methods may change without notice. We document material changes to the methodology on this page.
