<p>Hello, <br />Please can you tell me when Wave 6 will be released?<br />Thanks, <br />Dharmi</p> Understanding Society User Support - Support #509 (Closed): Using household identifier from xwave...https://iserredex.essex.ac.uk/support/issues/5092016-02-22T11:53:44ZDharmi Kapadiadharmi.kapadia@manchester.ac.uk
<p>Hello,<br />Please could you let me know if the following way is valid for merging household data into individual files. I am asking because I am aware that household identifier changes across waves if the household composition changes.</p>
<p>For my analysis, I want to have a measure of household income at Waves 1 through to 5. Therefore in order to do this, I brought the household identifiers (w_hidp) from xwaveid.dta for Waves 1 to 5, into the e_indresp.dta files using a m:1 merge. I then matched the household income from a_hhresp.dta to e_indresp.dta directly using a m:1 merge using a_hidp that I had previously brought in from the xwaveid.dta file. I repeated this for Waves 2 to 5. Is it correct to use the household identifier from the xwaveid.dta file, in this way? I thought it was, because even if the individual changes household over time, matching income from household files on the household id from a specific wave ensures that the observation is correct for that point in time.</p>
<p>The alternative method would be to merge household income into individual level files for each wave and then perform a 1:1 merge from individual files from Waves 1, 2, 3 and 4 into the Wave 5 file, matching on pidp. However, when I used this method, it resulted in 4,000 more cases of missing data for Wave 1.</p>
<p>Any advice that you can give on this issue would be much appreciated.</p>
<p>Many thanks, <br />Dharmi</p>
