Description

Hi,

I'm trying to compute a variable measuring how long it takes respondents to travel to work. To do this, I need to include self-employed workers, and so want to use jsttwt, however I notice that the variable doesn't actually record the respondent's answer in minutes, like the variable for those in regular employment: jbttwt (https://www.understandingsociety.ac.uk/documentation/mainstage/dataset-documentation/variable/jbttwt).

Is this information available anywhere? I notice that there is the jsttwtb_cawi variable for CAWI respondents (and which I assume therefore misses some respondents), but only available for the UKHLS waves.

Thanks,

You are correct.

The variable which records number of minutes taken to travel to work for those who are self-employed and the interview is not by WEB is recorded in w_jsttwtb (w_jsttwt just records whether they reported the distance or not).
The variable which records number of minutes taken to travel to work for those who are self-employed and the interview is by WEB is recorded in w_jsttwtb_cawi
The variable which records number of minutes taken to travel to work for those who are in paid employment is recorded in w_jbttwt

Please see the "Universe" below these questions in the questionnaire to know who is eligible for that question.

Hope this helps.

Best wishes,

Ah, that makes sense thanks. For some reason, I missed w_jsttwtb.

It seems that w_jsttwtb includes CAWI responses from wave 7 onwards though (from looking at the questionnaire). Is that right? I can see this syntax:

'Use
If (JSTTWTB_CAWI > 0) Compute JSTTWTB=JSTTWTB_CAWI;
Else: Ask;
'

Thanks,
Albert

Yes you are right. Even though the information is collected in two separate questions/variables for CAWI and non-CAWI interviews, these are combined into g_jsttwtb.
