KIDS Cycle 1, Primary File

Question

Our time was working on the KIDS Cycle 1, Primary file and discovered a
problem.

The Data List syntax for the primary file, cycle 1 contains an error for
variable AD1CS06. The syntax locates this variable in column 1603. However,
the variable is a two column variable and the correct location in the raw
data file is columns 1602-1603. The SPSS DATA LIST
syntax statement should be amended to read: AD1CS06 1602-1603. This
correction produces the correct unweighted frequency counts for this
variable, with a single exception: there is still one case with a response
code of 99 that actually should be coded 1 in order for the counts to match
those in the codebook.

What do we do here?

Answer

Regarding the NLSCY Cycle 1 Primary File frequency issue mentioned below,
the author division finally determined that the error is the PUMF codebook.
Here is their full response:

"we have finished the investigation on our end and it is the pumf codebook
that is in error. There may be other errors in the pumf codebook. We are
looking into redoing the cycle 1 pumf codebook."

If you notice any additional discrepancies between the counts and the
codebook, please let me know and I will pass them along to the division.

Please note also that a revised version of the SPSS file for the NLSCY Cycle
1 Primary File is available (as announced on January 19, 2009):
