Major findings of the study are summarized as follows:
The results of the examination of Census(0-4 age) show that Census data lack an accuracy in the the sense that the population of 1985-1990 were increased in comparison with the previous years. The comparison of actual sex ratios with the expected
ones
shows that actual sex ratios are higher tat expected ones in almost every region, which made the presumption that there was a delay in the reporting of births of daughters possible. The difference between actual sex ratios and the expected ones
in
wider
in urban area than in rural area. the data of 1985 Census were more accurate than those of 1990 Census. It is presumed that there were more overlapping reportings in 1990.
The comparison of the sex ratio of 1981 with those of accumulated years shows that the sex ratio difference was 2.8, which was decreased to 0.2 in 1991. The birth reports of children were made at the proper times and the difference in sex ratio
was
decreased. These facts explain that the birth reports of sons and daughters were made at the proper times. The exmaniation of Census data in comparison with Vital Statistics shows that the data of 1985 were more accurate that those of 1990. The
difference between the actual sex ratios and the expected ones in wider in 0 age group than in the age bracket of 1-4.
