Description
CALSEQREV supplies an index number for each month in the woman's recall timeline, beginning with the interview month, and ending with the earliest month in the calendar. Thus, the highest value in CALSEQREV for a woman refers to the first month recorded in the calendar.
Values for CALSEQREV reach at least 60 for all women in all calendar samples included in IPUMS DHS. The highest value for CALSEQREV, and accordingly the number of months comprising the recorded calendar period, varies across women in a given sample and across samples.
For example, all women in the Bangladesh 2018 sample have CALSEQREV values running from 1 to 70, but decreasing numbers of women in that sample also have CALSEQREV values (and thus months of reporting) ranging from 71 to 75. In the 2007 Bangladesh sample, all women have CALSEQREV values up to 63, and diminishing numbers of women have CALSEQREV values up to 68.
If an analysis requires that women compared have comparable periods "at risk" of reproductive events, then researchers may wish to limit the period analyzed to exactly 5 years (60 months), working forward from each woman's month of interview (starting with the initial value in CALSEQREV).
The differing number of months indexed by CALSEQREV reflects the fact that the recording period begins in January for the earliest calendar year, but interviews may start later in the year and, for some surveys, fieldwork is spread across several months.
Comparability
Along with universe differences between samples, the maximum value for CALSEQREV varies across women in a given sample and across samples.
Comparability - Standard DHS
CALSEQREV is a technical variable created by IPUMS DHS staff during the processing of calendar string data from the women's (IR) files.
