universe of indall files in BHPS UKHLS
100%
Description
Dear Sir/Madam,
Hi, I have a question on the universe of indall files. To investigate the reason for sample attrition, I have merged interview outcome code (ivfio) in indall file with pooled inresp longitudinal file. I have found quite many people who have appeared in the indresp file in the past, do not show up in the future indall file. I have expected them to appear in indall file with information on non-interview reason but many of them simply did not appear. To investigate whether these people were not original sample member of the study, I have looked into sample status variable (sampst) as well. However, many original sample members did not appear in indall file even though they interviewed in the past, and some of them return again to participate in interview after not showing up in indall file and indresp file for a few waves.
Could you please explain why indall file does not capture every sample member of the study?
Thanks!

Dear Yujung Whang,
The w_indall files contain everybody who is enumerated in a responding household in that wave, so if the whole household did not respond there will be no records for them in w_indall. The w_indsamp file contains the information you are looking for. Also, the xwaveid file includes the interview outcomes at every wave (if fielded) for everyone ever enumerated in the survey.
Best wishes,

Hi, Thank you for your kind reply.
I have checked xwaveid data to see if interview outcome was recorded for every wave since the first enumeration. I found for many individuals, interview outcome code appears as "not applicable" after first enumeration. To tabulate the reason for sample attrition after first enumeration, I wonder when the interview outcome code stops being recorded. Could you please explain a bit more when the interview outcome code is coded as "not applicable"?
Thanks,
Yujung

Dear Yujung,
Apologies for this delayed response. We had a problem with receiving notifications of forum updates on the day you posted.
These cases are those respondents who were not issued to field. Some of the main reasons are (i) TSMs who are now in households with no OSM/PSM and so will no longer be followed (unless they move in with a OSM/PSM), (ii) sample members who have been non-respondents for a number of waves and so no fielded, (iii) have been an adamant refusal and so were withdrawn, (iv) died. You can find out more about the reasons by checking the respondents’ values of ivfho and ivfio in the wave previous to where the interview outcome code is “not applicable”.
Best wishes,
