That PIDP may change over time as a result of new information coming through in a particular wave, for example, as the parent realises we make a distinction between natural and adoptive parents and they are not in fact a natural parent. Another route is that the parent’s gender may be incorrectly recorded in the study data base in a particular wave (resulting in mother and father switch) or there may be same-sex parents but only one can be recorded in the gender-specific pointer. Another route for inconsistencies across studies is that the information is asked differently: in the BHPS, household relationships are inferred from the relationship to the head of household; in the UKHLS relationships of each person are asked directly.</p>
<p>There will not be many cases with cross-wave inconsistencies. But (like all data errors/inconsistencies) these should be investigated; if you have a better idea about why the inconsistencies occur you can decide for yourself how to deal with these cases in your specific analysis.</p>
<p>Note that the UKHLS provides both the PID and the PIDP for respondents who already participated in BHPS W1-18. However, BHPS sample members who did not already appear in BHPS W1-18 will have their PID in the UKHLS set to -8 "inapplicable" (like all members of the new UKHLS samples). Therefore, for those pairs who occur in the BHPS W1-18 you could rely solely on the PID but for all others you have to use PIDP (or generate a new unique ID that works across studies). Once you have created an ID that works across studies and cleaned the parent-pointers, linkage is straightforward (as you describe).</p>
