## About "census" in BIP39

- "census" has 6 letters, but the first four, **"cens"**, already identify it, because **"cen"** also begins [century](/bip39-word/century/).
- **"cens"** is unique only within the English list: it also begins censurer in the [French list](/french/) and censo in the [Portuguese list](/portuguese/), so a four-letter backup should say which list it uses.
- "census" appears in one of the 24 official English [test vectors](https://github.com/trezor/python-mnemonic/blob/master/vectors.json) of BIP39: vector #21 (word 15 of 24). Every official vector passes the [checksum checker](/bip39-checksum-checker/), and [How BIP39 works](/how-bip39-works/) shows how the entropy turns into such words.
