Replicate family structure estimates

We are trying to replicate family structure estimates found in table C3 at https://www.census.gov/data/tables/2019/demo/families/cps-2019.html.

With the 2019 CPS data, we created three family structure variables: two parents, one parent and no parent. Then we created a subpop of those who completed the ASEC, and excluded group quarters and entries that are either the reference person or the spouse (as indicated below the table). Our estimates for total N match when we restrict the age to under 3, and the published estimate is within the confidence interval for two parent and one parent. However, we are underestimating the no parent number.

Does anyone have any insight into how to replicate the published family structure estimates? Thank you!

Just to clarify: Are you using the weight variables?

Yes, we are using asecwt because the published estimates use ASEC data only.

I noticed this note in table C2 for children living with neither parent: “Excludes children who are also in a subfamily.”

The numbers in table C2 line up by age with the numbers in table C3, so I assume this note should also apply to table C3. I’m not entirely sure how to interpret that, but it might help get you closer. The IPUMS variable FTYPE identifies individuals in subfamilies.
