Description

Dear Support Team,

I am computing the poverty line for each wave of BHPS and UKHLS, as indicated by the files in the
Moodle X courses (attached for your convenience).
I have some questions on the BHPS file.
1) Fihhmn is indicated in hhresp but I have found it only in indresp. Was it recalled otherwise?
2) I am not sure about the weights used for computing the pov line in BHPS. The file uses the individual
weight xewght. However, the variable is at hh level. Shouldn't I use a hh level weight, like xhwght?

Thank you and best,
Lydia

Lydia,

I am answering here your question regarding weights. The weight you use will depend on the level of analysis. If you analyse households and want to talk about households you will need household weight. But if you are talking about individuals (with household level characteristics for example) you should use individual level weights.

Hope this helps,
Olena

Hi Lydia,

If you are interested in gross household monthly income, then please use the variable called bw_fihhmngrs_dv in bw_hhresp.

Dear Support Team,

I have a question that relates to this post. I noticed that in the example for the BHPS (see post #1), the poverty line is determined using the individual weight (axewght), although there is also a household weight in the household data. Using the individual weight is the procedure I know from other panel datasets.

However, in the example for the UKHLS, the household weight (a_hhdenus_xw) is used to calculate the poverty line, but the individual weight (a_psnenus_xw) to estimate the poverty rate. Why is the individual weight not applied in both cases?

Best wishes,
Nico

Sorry for the delay in responding Nico.

When calculating the poverty line in Example 4, the datafile being used is w_hhresp. This is a household level file and so the data is available for responding households. As a result the appropriate weight is the household level weight - w_hhdenu?_zw.

In the next part of the example when poverty rate (proportion of all individuals who are in households with equivalised household income below the poverty line) was being computed, the information of poverty line was merged in with the w_indall file which includes all household members enumerated in the survey in that wave. So, the sample being used to compute the poverty rate was every in the w_indall file and so the appropriate weight was w_psnenu?_xw.

Hope this answers your question. If not, please let us know.

Best wishes,
