Variable for year of birth of someone in the census?

I have seen that there are AGE variables for each census but I would do like to know if there is a variable for year of birth.

Thank you.

The year of birth variable is BIRTHYR. It is broadly available across most census samples. Do note, however, that self-reported birth year is available only for the 1 percent samples for 1900 and 1910, as well as the 1900 100% file. In all other samples, self-reported birth year is not available but has been calculated by subtracting AGE from the survey year.
