This site is under construction. What you see here is real data from tables we have already built; the full site is on its way.

Every question you can ask about two countries, one table each.

Do they share a border? Does a custody ruling from one hold in the other? Do their tax offices swap bank records? Who sells what to whom, and who beat whom at football? CountryPair answers each of these for every pair of countries, with the source and its date next to the answer.

Three pairs, as they stand today

Where this is going

The finished site will open any pair, any country and any table, and show what changed since your last visit. We add tables every week: visas, tax treaties, extradition and embassies are next. If you want a note when it opens, or you hold data that belongs here, write to us.
