Description

CALPREG_LC is a flag variable indicating whether the months of a reported pregnancy, including the month for the birth or termination that ended the pregnancy, were left-censored, or truncated, by the start of the calendar period. If the earliest month of the calendar period for a woman included a pregnancy, birth, or pregnancy termination, then every month of that pregnancy during the calendar period (including the month of the birth or termination) is coded "1" (yes), as left-censored.

The related variable CALPREG_RC flags all months of a pregnancy that overlaps with the end of the calendar period. Pregnancies that ended with a birth or pregnancy termination in the final, or interview, month of the calendar period were not considered right-censored.

Because the length of a pregnancy cannot be determined if that pregnancy is left- or right-censored, truncated pregnancies are excluded from summary variables about the duration of a pregnancy (including the month of birth or pregnancy termination). Specifically,

For further discussion of how IPUMS DHS's calendar data handles truncated pregnancies, see the documentation for CALPREG_LENGTH.
