Estimation life expectancy in Gaza Strip using brass growth balance method

الملخص EN

Life expectancy is an important demographic indicator that is used for comparison between different population groups.

A life table is designed mainly to measure a life expectation.

Incompleteness of death registration is causing a problem to estimate the life expectancy.

In this paper, we estimated the life expectancy for Gaza strip using population and mortality data from the Ministry of Health.

Estimation of the corrected life expectancy in Gaza strip was conducted by correcting the incompleteness of death registration by Brass growth balance method.

By using Brass growth balance method the uncertainty interval was much smaller than that computed without correcting underreporting.

The estimate of life expectancy at birth for the total population of Gaza strip in 2006 is about 1.41 year higher than the estimation when correcting underreporting with Brass growth balance method.

It is about 2.2 year higher for males and only 0.35 year for females.

It is found that this difference is statistically significant for males and both sexes only.
