What is the definition of foster child in the data set?

I have a question related to the varibale RELATE in the dataset. I was wondering what is the definition of Foster Child in the data? Because I see that some respondents have foster children whom are older than 50 years old!

thanks in advance,

For the ATUS, RELATE was collected directly from the respondent by the enumerator at the time of the ATUS survey. The RELATE variable simply records this self-reported relationship, rather than imposing a uniform definition. You can also check the data quality flag QRELATE to see if a value of RELATE was allocated.

Hope this helps.
