If you're an investor, agent, or developer working in the Vienna property market, you've probably experienced the same frustration: the data is always late. Central banks publish quarterly reviews. National statistics offices update dwelling data annually. Industry reports come out every few months. By the time you read them, the market has already moved.
Major property portals show you what's available today — but they don't tell you where demand is heading, which districts are heating up, or how the market is shifting. You get inventory, not intelligence.
That's the gap METROX was built to fill. The METROX Demand Index is a composite score from 0 to 100 that aggregates public market signals across all 23 Vienna districts. It is a proprietary AI-derived score based on aggregated public market signals, search-interest indicators, advertising indicators, search interest, web-activity and marketing-analytics signals — into a single number that tells you whether a district is cooling down, warming up, or in a seller's market.
| Data Source Type | What It Provides | Update Frequency | Demand Insights |
|---|---|---|---|
| Central bank reports | Price trends, market reviews | Quarterly | None |
| National statistics | Dwelling stock, floor space | Annually | None |
| Industry reports | Market overviews, forecasts | Semi-annually | Limited |
| Property portals | Asking prices, district samples | Aggregated indicators | None |
| METROX | Demand index, price trends, district analytics | Daily | Daily, per district |
Here's how the index works in practice. A score of 50 means the market is balanced — roughly equal numbers of buyers and sellers. Below 40 indicates a buyer's market with excess supply. Above 60 signals a seller's market where properties move quickly and competition drives prices up. The current Vienna-wide score sits at 52, indicating a steady market with warming signals.
But the city-wide number only tells part of the story. District-level data reveals dramatic differences. Innere Stadt (1st district) scores 73 — firmly in seller's market territory, with properties selling in under 21 days. Meanwhile, outer districts like Liesing (23rd) and Simmering (11th) hover around 46-52, with more inventory and longer selling times.

The index updates daily, drawing from multiple data streams that are aggregated, normalized, and weighted to produce a single actionable number. The weighting formula prioritizes search-interest ratio (how many people are looking versus aggregated district sample size) at 70%, with market velocity (aggregated activity indicators) contributing 30%.
For investors, the demand index answers the most fundamental question: where is the smart money moving? A district with a rising index score and below-average prices represents an opportunity. A district with a high score and already-elevated prices suggests the window may be closing.
For agents, the data enables evidence-based conversations with clients. Instead of anecdotal impressions, you can show a client that their district has a demand-to-supply ratio of 1.8× — meaning nearly twice as many buyers as available properties. That's a data point that changes pricing strategy.
For developers, the METROX dashboard provides a macro view of where new supply is needed most. Districts with sustained high demand scores and low new construction activity represent the strongest opportunities for new residential development.
The platform is free to use and accessible at metrox.io. The dashboard includes an interactive map of all 23 Vienna districts with color-coded demand scores, a trend chart showing index movement over time, and detailed district-level analytics including price per square meter, aggregated market velocity, and district activity tier.
METROX is currently focused on Vienna, with plans to expand to Graz, Salzburg, and other Austrian cities. The goal is simple: make real estate market data as accessible and timely as stock market data. Because in a market where prices can shift 3-5% per quarter, waiting for a quarterly report is no longer good enough.
