KIDBIRTHYR_NP_ALL (B2_x) variables are 4-digit variables.

9999 = NIU (not in universe)

Description

KIDBIRTHYR_NP_ALL (B2_x) reports the child's year of birth, according to the Nepali calendar. This variable is only available for the Nepali samples.

KIDBIRTHYR_NP_ALL consists of a set of twenty separate variables, covering the most recent birth (KIDBIRTHYR_01) up to the twentieth-most-recent birth (KIDBIRTHYR_20) for a female respondent of childbearing age. If KIDBIRTHYR_NP_ALL is included in a data extract, all these separate variables are included in a researcher's data file.

Information for this variable was collected on all births for a woman, up to a maximum of twenty births. In many cases, data were hypothetically collected on up to twenty births, but no women in the survey had so many births (e.g., no woman had 19 or 20 births). If, for example, no woman in a survey had 20 births and only blank values were included in the original DHS file, then KIDBIRTHYR_20 would not be available for that survey in IPUMS-DHS.

Comparability

Apart from universe differences, KIDBIRTHYR_NP_ALL (B2_x) has no comparability problems across Nepali samples.

All standard date variables in Nepal DHS samples are given in the Nepali calendar. The Nepali calendar, or Vikram Samvat, is a lunar calendar consisting of 12 months of 29 to 32 days each. According to the Gregorian calendar, the Nepali calendar begins in mid-April. Because the 12 months do not match the sidereal year, correctional months are occasionally added or subtracted. It is only possible to convert dates given in Vikram Samvat to the Gregorian calendar when the exact date (day, month and year) is available. Otherwise, it is only possible to approximate to the month. Vikram Samvat is approximately 56 years, 8 months, and 15 days ahead of the Gregorian calendar.

Comparability - Standard DHS

KIDBIRTHYR_NP_ALL (B2_x) is included in every phase of the standard DHS questionnaire for Nepali samples.
