# Year of birth (`birth_year`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Year in which a person was born, written with four digits, for example 1984. Data sets publish it instead of the full date of birth to make people harder to identify, but it is still personal data.

- Parent datatype: `year`
- Personal data (PII): yes
- Categories: Person related (persons), Personally identifiable information (pii), Date and time (datetime)
- Countries: global
- Languages: Common to most languages (common)

## Detection

Regular expression (Python `re`):

```
^\d{4}$
```

## Examples

- `1984`
- `2001`
- `1984-05-17` (invalid example) — a full date of birth is the datatype birthday
