Answers use saved listing facts and recorded sources.

What it does

Bonn's open-data portal groups datasets across population, education, geography, housing and other city topics.

Check the year and format in the catalogue before opening a result. Visible CSV examples include 2025 cycle counts, 2026 waste-collection schedules and 2025 newborn names. Those are separate reporting periods and uses, rather than one common municipal update cycle.

How the SI Score works →

Unconfirmed details may be unassessed, absent from the pages checked or temporarily unreadable. A missing price does not mean the service is free.

Sources and checks

Supporting pages for product usefulness, site facts, prices and separate website checks. Each record keeps its own date. Reading a page does not establish how well the product performs in use.
