Understanding Society User Support

Dear all,

I am currently dealing with the variable `w'NWSTAT of BHPS. In UKHLS, I have the possibility of understanding if the household where alter or ego live in the following wave is still in the sample.

In BHPS, I do not understand if the value "2" assumed by NWSTAT refers to the fact that alter lives in a household that is still in the sample or if
this information is simply not available.

Thank you and best,
Lydia
