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).
