aving taken 1981 as tho bae year, we rhall conaider fou r
different targat years, n ma ly, 198G, 1981, 196, and 20 1 .
Assumption regarding C : According to the 1981 population
m
cen&us, currently mazrried woman constituted 04% of a Ll women in
the age-g roup 15-49. This moans C for 1981 w a e lual to 0 .840.
a
A common assumption foroang t nd3sh is that tho average age at
marriage is gradual ly increusing. Tharefore the value of C can
m
be a ssumed to decreasa by 0.005 aftor every five years, as shown
ba low:-

Assumption regarding C a The Population Council's formula
a
for estimating the index of i naducad abortion is
TFR
C =
TFR ... (4.7]
+ 0.4 x (1 + overall CPR] x Total induced
abortion rato
This formula for C needs prior knowledge of overa L L CPR, but tne
a
formula for CPR also needs prior knowledge of C . To bypass tha
a
circularity problem, thu overall CPR can be
C
(t)
approximately
calculated by assumi ng that------- = I This iG justified
C (0]
because chargas in CPR in Banglada h are Linked primarily with
changes in TFR, and C
a
has no major role.
