Vienna Trade Density Index
How dense is each trade in Vienna, really? This report converts official GISA data into licences per 10,000 residents — for 20 sectors, all 23 districts, with the movement since July 2025. Every number on this page is computed directly from the dataset; nothing is typed in by hand.
Key findings
- IT services is by far the densest sector in the city: 82.0 licences per 10,000 residents (16,744 in total) — ahead of Business consulting (52.6) and Gastronomy (37.6).
- The biggest growth since July 2025: IT services, +1,425 to 16,744 licences. Followed by Advertising agency (+650) and Business consulting (+449).
- 5 sectors shrank, led by Construction (Baumeister) (−59 to 1,395).
- Density is an inner-city phenomenon: Gastronomy reaches 599.5 per 10,000 residents in its top district, Innere Stadt (1010) — roughly 16× the city average. The big exception: Taxi.

Counted are trade licences as recorded in GISA — a licence is not the same as an economically active business.
The inner-city distortion — and why it is real
“Per 10,000 residents” normalises by residential population. The Innere Stadt has few residents — and many company seats, office and walk-by locations. That is why Gastronomy reaches 599.5 per 10,000 residents there, roughly 16× the city average of 37.6. This is not a data glitch: density follows where businesses sit and customers pass by — not where people live. It is exactly why the district rankings on our trade pages filter out districts below 20,000 residents.
The counter-example is Taxi: its top district is Simmering (1110) at 32.6 per 10,000 residents against a city average of 21.2 — the sector spreads almost evenly across the city.

Methodology
- Source: GISA (Austria's trade information system) via data.gv.at, licensed CC-BY 4.0; population figures from Statistik Austria.
- Metric: trade licences per 10,000 residents of the respective area, as of September 2026.
- Time series: from July 2025. June 2025 is deliberately excluded — the GISA system transition produces an artifact there that would distort any trend statement.
- Updates: monthly with the dataset; the date shown at the top is the snapshot month of the source.
