Two cities with very different history, geography and scale.

Capital of Poland · on the Vistula · largely rebuilt after its destruction in the Second World War.
We only publish what has a source. For this pair, that means some things a Sister Cities Hub would show are still missing.

Data gaps
Istanbul's latest population figure in the Eurostat Urban Audit is from 2004, and its Community dimension has no measured data. The comparison above marks gaps instead of filling them.

We're looking for partner cities to pilot the Sister Cities Hub with. If you administer either side of an existing twinning agreement, email us with the cities and we'll talk.
