time she was not employed during the interval as longer than the length

Note: For ever married women who reported that they were employed during
this interval, this variable represents the length of the interval minus
the time not employed during the interval. For women with more than one
job during the interval, this variable can overestimate the total time,
in months, that the woman was employed, depending on the length of the
labor force interruption between the two jobs. Any woman who reports
having worked during this interval and who reports that the length of
time she was not employed during the interval as longer than the length
of the interval is scored 0.

For the one person with twelve children, we calculated this variable by
hand, using data on the birth of the eleventh and twelfth children.
