Hi, I'm currently working on a cross-sectional study across waves to examine the proportion of children who live in couple-parent families where one parent reports any form of relationship distress.

I have three questions relating to weighting:

• From this analysis, I've seen changes to weighting across all previous waves and I would like to know what specifically led to the revisions?
• Since I'm looking at participants across waves, I'm also interested in whether there is any attempt to mitigate attrition bias (e.g. changes to weighting)?
• Given that I'm working with w_psnenui_xw weights for my study, Do you think this weighting is appropriate for examining this area of the USOC Survey data?
