Fertility

Description from Hirschman et al 1992:
The dependent variable is an index of current fertility- -the number
of surviving children, aged 0-2, of each woman in the sample. Based upon
the own-children methodology (Cho, Retherford, and Choe 1986), each child
is matched with his or her mother in the household. In order to provide
a more intuitive index of fertility, the dependent variable is weighted
to represent the number of children a woman would eventually have if her
current fertility continued for a span of years in her reproductive career
(akin to a total fertility rate). To obtain an annual rate, the total number
of surviving children is divided by 3 (because children age 0-2 were included)
and then multiplied by 15 (the number of years in each of the two age categories
of women: 15-29 and 30-44) in order to estimate a synthetic cohort rate.
(In the early stages of the project, an annual fertility rate was established
by taking the total number of surviving children and dividing this by four,
because children aged 1-4 were included. This age range was used because
of the high percentage of undernumerated children, age 0 in the 1971 Indonesian
Census, see Cho, 1980, p.31) The index of current fertility is also adjusted
upward for the proportion of unmatched children in the sample, assuming
that unmatched children were randomly distributed. Plus we adjusted fertility
to account for infant mortality at the province level and a woman's own
experience with child death. The project currently uses an adjusted fertility
measure based on children age 0-2, adjusted for the percentage unmatched
and infant mortality in the province/district.
