The advanced two-niche overlay compare tool is currently available in the German version only. It includes normalized overlay charts, preset comparisons, shareable URLs and a Google-Trends deep-link — all translated UI strings will follow as the English mirror matures.
Why only 13 months — and what's coming
Today
13 monthly data points (March 2025 – April 2026). This is the maximum horizon the official GISA dataset currently provides — standardized anonymized monthly snapshots weren't published before.
In one year
~25 months. The time series will be long enough for the first seasonality patterns — registration peaks in January, closures after Christmas — to become visible.
In three years
~49 months. Long enough for real trend lines and "before-and-after" comparisons of specific events. Only then does the tool really work like a stock chart.
How to read these charts
For beginners
Each chart shows how many active business locations existed for that trade in Vienna each month. If the line goes up: more businesses. Down: fewer. The percentage in the top-right is the net difference between the first and last month.
Important: a shrinking stock isn't automatically a warning sign. It can mean old businesses close while new ones open — then the market is in motion even if the total shrinks. We track that motion separately on each niche page.
For insiders
The vertical dashed line in May 2025 marks the switch from annual-report to monthly-report snapshots. Values before are point-in-time accurate (first of the month); after are monthly aggregates. The visible "kink" is not a real market dip, it's a methodology artefact.
For statistical work, use the window from May 2025 onward (currently 12 months). The churn index on niche pages calculates only within this window.
