Description

Greetings!

I am merging all the income datasets with the 18-wave BHPS and the 8-wave UKLHS. However, the row in income is not uniquely identified by fiseq_bh and pidp in wave B1, B3, B9, B10, B11, B15, B16, B17 and B18 (especially for the B17 and B18). Then I have tried to use fiseq_bh, pidp and ficode to identify rows. Still, there are about 360 rows are not uniquely identified by the three variables. Those repetitions are from the B17 and B18.

Could you please provide any suggestions on it? Do you have any documentations to explain how the rows are identified for each dataset?

Best wishes,

Yanan

Dear Yanan,

Thank you for bringing this issue to our attention. Some of our team members are looking into it and we will continue to update you with progress. This investigation may take some time due to the time passed since the data was collected.

Best wishes,

Dear Yanan,

We are working on documentation for the unique identifiers for each dataset.

In this case, pidp and fiseq_bh do not always uniquiely identify the row. We think that this may be because sometimes the script reset fiseq_bh for each type of income receipt. Ficode is a harmonised version of ficode_bh, which has some categories from ficode_bh combined for use with UKHLS data. If you use pidp, fiseq_bh and ficode_bh then these variables together will uniquiely identify the rows.

Best wishes,
Stephanie
