Linking children in MTUS to both parents

Hello,

If I wanted to link children to their parents in the MTUS sample, how can we know for sure that a child is the child of both the reference person (using relrefp) and the partner or spouse of the reference person? I assume that’s true in most cases, but one obvious exception would be when the reference person is in a second marriage and the child is from a previous partnership.

Thank you so much!

Unfortunately I am not aware of any variables in IPUMS MTUS samples that would allow you to determine the parentage of household children with more certainty. In some samples, there is more information available in the original data that would allow you to explicitly identify parent-child relationships and other relationships between household members. If this information is critical for your work, I would suggest looking through the original survey documentation and reaching out to the Centre for Time Use Research to request access to additional variables. I am not sure whether they would be able to provide this, but since they are the source of the data we provide via IPUMS MTUS, that is likely your best bet.

That makes sense, thank you!

Hello,

I hope you’re doing well. I had a couple of follow-up questions with the MTUS harmonized dataset, specifically surrounding income.

While reviewing both the codebook and the underlying data, I noticed some inconsistencies:

  1. France 1998–99
    The codebook indicates that this sample should have grouped income categories. However, in the actual dataset, the income measure appears to be continuous. I just want to make sure I’m not missing anything here.

  2. France 2009
    The dataset reports income categories coded 1–5, but the IPUMS codebook does not provide any category definitions or income bounds for these groups. Do you know is such a codebook exists for this sample?

Thank you for all your help so far!

I see that we do not provide value labels for the codes for INCORIG in the France 2009/2010 sample.

I also see that the codes provided in the INCORIG metadata for the France 1998/1999 sample do not align with the codes in the actual data. Here are the codes and frequencies in the data:

And here are the codes listed in the INCORIG codes section:

These codes and labels come from the CTUR’s harmonization documentation, but evidently they do not match the data.

I have inquired with our IPUMS Time Use team about these two issues. I will follow up with you when I have more information to share. Thank you for your patience.

Thanks for reaching out!

I’m writing to let you know we are still waiting for more information on these variable codes, and I will post here when we have something to share with you.
