The aim of the present study is to estimate some mortality
measures such as the age specific death rates (ASDRA), infant
mortality rate (IME) and me table crude death rate (CDR) for male,
female and both sexes of Bangladesh in 2005. For this purpose, two
abridged life tables, one for male and other for female were
constructed using the corresponding secondary data on life
expectancy at birth of Bangladesh in 2005 taken from Islam (2003).
These were compared to the values in 199] and it was observed that
these rates were showing decreasing trend during 1991-2005.
Moreover, a mathematical model was fitted to the number of
persons surviving at an exact age x (lx) only for male of Bangladesh
in 2005. Model validation technique, cross validity prediction
power (C VFP) and F-test, showed that the mathematical model was
valid and hence, fit is well. Instantaneous force of mortality ( |J. X )
only for male of Bangladesh in 2005 was estimated And it was
found that |.L X exhibited decreasing trend up to age 20-24 and
increasing in the remaining age group but rapidly increasing after
age 50 years to infinity.
