Data quality flag for FREVER


This variable is not available for any of the currently selected samples.


QFREVER is a data quality flag for FREVER.

This variable is a part of the CPS Fertility Supplement.


QFREVER frequencies and coding in the 1987 sample are inconsistent with surrounding samples. The data is not reflective of the documentation in 1987. The data quality of this flag is suspect in this year. When values labeled as “allocated” in the documentation are taken as such, the allocation rate is suspiciously high. Unlabeled codes make it unclear if there is any coding error in the original CPS data. A code of 1 indicates allocation, while a value of 0 indicates no allocation. However, in addition to these codes there are also values of 2, 3, and Blanks in the original data. IPUMS CPS has left allocations coded as printed in the codebook and recoded unlabeled codes as NIU. Researchers should exercise caution when using QFREVER in the 1987 sample.
