Czechia ~46.816
Roughly ~46.816 people are active on and around AT Protocol in Czechia.
Two main numbers
How we estimate this
AT Protocol has no country field, so we cannot count directly. We measure posting activity per language across Europe, weight each language to the countries where its speakers live, and calibrate the whole model to the Dutch figure on atproto.nl. Language only feeds the estimate; it never confirms that an account belongs to Czechia.
What we can stand behind
501 accounts we can place in Czechia for certain, each from a deliberate signal. The real number is higher, which is what the estimate models.
Where these accounts come from
Those 501 accounts by the signal that placed each one. Every account is counted once, under its strongest signal.
What it cannot see
People who post mainly in English are invisible to a language model, so an English-first account in Czechia is not captured, which is part of why the real number sits above the confirmed floor.
