| Metro population (city plus commuting zone) | Not in our data yet |
A Eurostat "greater city" is the area Eurostat uses when a city's urban centre stretches well beyond its administrative boundary. It is a different definition from a single municipality and from a metro area (a city plus its commuting zone), so other population numbers you see may describe a different area. Municipal, greater-city and metro populations are different ways of defining an area, not a population time series. We have not linked a municipal or metro population to this page; adding one needs a verified area relationship and data approved for display.

About this page's data
Every figure on this page comes from Eurostat's City Statistics, the EU's official statistics for cities. National statistical offices supply most figures. This page lists 8 of the figures Eurostat publishes for the Troisdorf greater-city area. Each figure carries its own year, and years differ, so the page is not a ranking or a like-for-like comparison with other cities.
Eurostat and the national statistical offices define the exact area of the Troisdorf greater-city area; this site does not yet publish a boundary map.
The page name is the label Eurostat uses for this area: Troisdorf (greater city) (Eurostat provider code DE136C).
Updated September 2026: we last refreshed these figures from Eurostat on 1 September 2026. Each one is the newest figure we can show for this area from that data, and each shows its own year. Reporting dates and availability vary by area and indicator.
Missing figures stay missing. We never fill a gap with a regional or national average. We plan to add which country the area is in and a map, climate and metropolitan-area population once each has passed its own source and rights review.
