Description

Hi,

I'm currently working with Wave R of the BHPS, and I have a query about missingness in the parental occupation (and education) variables. The vast majority of responses to these variables (e.g. paseg) are 'inapplicable'. I can see that this is because this question is only asked of new sample members. I have therefore matched in this information from xwavedat. However, this still leaves 4,000 or so cases coded 'inapplicable'.

From a previous post (https://iserswww.essex.ac.uk/support/issues/570) I can see that sample members who were originally children in sample households (and who completed the youth survey) were not considered to be new sample members and were therefore never asked this question. This would account for some of the missingness, but it doesn't seem like it would account for all of it.

Are 4,000 of the Wave R sample members really former youth survey completers? Or are is there some other reason that some Wave R members will not have been asked this question?

Cheers,
Rob

Thanks Stephanie,

I have a quick update to this. I found the syntax Alita Nandy helpfully uploaded (https://discover.ukdataservice.ac.uk/catalogue/?sn=6614&type=Data%20catalogue) to match in parental information for sample members whose parents were also sample members. This helped quite a bit. Matching this information into Wave R means that I now have about 2,300 'inapplicables' for rpaseg rather than 4,000. Combining information from rpaju, paju (from xwavedat) and the jbstat variable for parents who are sample members (using Alita's code) shows me that about 220 of these are 'inapplicable' because they were not working (and therefore couldn't have a SEG). However, that still leaves almost 2,000 sample members with no information about their father's job.

By a process of elimination, it would seem that these 2,000 must be rising sample members (who were therefore never asked the 'parents at 14' questions) whose father's are not present in the data for some reason or another (death, divorce, or non-response). Is this correct? Because it still seems like quite a large proportion of respondents...

Cheers,
Rob

Dear Rob,

Apologies for the delay in response. We are still investigating some of these cases and should be back with an answer shortly.

Dear Rob,

There are a variety of reasons for these missing values as follows:

As you say, some are rising 16s who were not asked these questions – some of these had parents who responded when the respondent was 14 and so these values can be used as in Alita’s code.

The parents’ occupation questions were not asked in Waves 2-7 of BHPS, so anyone who joined during those waves will have that information missing.

These questions were not asked as part of a proxy interview, so if a respondent’s first interview was a proxy interview they will not have been asked, and if the respondent answered “don’t know” then the value in xwavedat will also be missing. You can check if these either of these situations were the case in the indresp file for each wave.

The largest group of missing values in pasoc and masoc are those in the Northern Ireland part of the sample which was added at Wave 11. These respondents’ parents’ jobs were not coded to SOC90, but only to SOC2000. The values of pasoc and masoc in xwavedat are based on the job status on the SOC90 code, but you can pick up these values by going back to the indresp files for each wave from 11 onwards. One thing to understand here is that wmaju and wpaju only have valid responses if the parent was not working. If they were working then this is recorded in their SOC code, i.e. for NI respondents in wmasoc00 and wpasoc00. paseg and maseg should be coded as usual for NI respondents.

SOC and SEG codes are coded from free text so if it was not possible to tell what code to give from what was written during the interview then the data will also be missing.

Parents’ education is only asked at Wave 13 of BHPS so anyone who did not respond at that wave will not have been asked, and proxy respondents were not asked.

Once again, apologies for a delayed reply, and please get in touch if there's anything else we can help with.

Best wishes,
