B5 variable represents whether child was alive or dead at the time of interview.
B6 Age at death of the child as reported in the questionnaire. The first digit of the age at death
gives the units in which it was reported: 1 - Days, 2 - Months, 3 - Years, 9 - Special
responses. The last two digits give the age at death in those units. Age at death is usually
reported in days if it was less than one month, in months if it was less than two years and
otherwise in years. If the last two digits contain a value greater than 90 then this is a special
response. For example, 298 means the age at death was a number of months, and the exact
number was unknown, but lies between 1 and 23 months.
BASE: Dead children (B5 = 0).
B7 Age at death of the child in completed months gives a calculated age at death from the
reported information. If it was reported in days these are truncated to completed months, if
reported in months these are used directly, but if reported in years then truncated years are
used, i.e., 3 years becomes 36 months. For ages at death that were not specified, an age at
death is imputed using a hot deck approach by taking the same age at death as the last child
encountered of the same birth order in the data file. This variable is no longer truncated at 90
months and now occupies three digits.
BASE: Dead children (B5 = 0).
