Description

I have a question on LDA sample (low density area non-white background sample). I found many extra 5 min questions were asked to LDA sample as well (condition in codebook was "GRIDVARIABLES.LDA = 1". However, I could not find an explanation on (i) sample size/how they were collected in the most recent User guide. Also, (ii) I could not find an identifier variable in the published dataset whether the respondent was drawn from LDA sample.

Could you please provide me more explanations on (i) and (ii)?

Thanks a lot,
Yujung

Hi Yujung,
the LDA indicator refers a characteristic of the neighbourhood in which households lived in wave 1 (proportion of ethnic minorities in the area) and is included in data file HHSAMP (_lda) in waves 1 only.
The design of the ethnic minority boost sample, including a full description of low density areas, is described in detail in this working paper:
Berthoud et al. (2009). "Design of the Understanding Society Ethnic Minority Boost Sample." Understanding Society Working Paper 2009-02. The User Guide refers to this paper in many different places.
Hope this helps.
Best wishes,
Gundi
