Abstract
Discussed the errors associated with Demography census data , focusing on population census data for the evaluation of the target in 1997 and revised note that the search did not include the provinces of Kurdistan region ( Erbil , Dohuk and Sulaymaniyah ) because the 1997 census did not include these provinces . After using the five methods for correcting age structure data and qualitative ( scale Myers , Whipple scale analysis , the proportion of age , gender analysis , measurement of the secretariat of the United Nations ) . Research found there were errors in the age structure data and qualitative measurement in Whipple found that the degree of accumulation at the age of the males (105.6) As the females were ( 106.7 ) . As Myers found that the measurement of the accumulation value of age for males was (4.2) , females were either (6.1) for the analysis of the proportion of the value of life was attributed to deviations from the old (100) total (138.2) for males and (91.3) for females , which indicates the presence of errors These errors were larger in males than females are , as the accuracy in the measurement of age for males (9.9) and (6.5) for females than males indicating that less accurate to make their age females . As for the analysis of sex ratios (sex) results indicate the existence of a deviation in sex ratios from the general pattern , where it appears that the ratio was high for the typ of (100) in the young age (before the category (20-24) ) and then declined until it reached to (100.2) at ages younger age group (25-29) . The volatile than in the age groups (30-34) to (40-45) and then rose suddenly from the (100) in both categories (50-54) and (55-59) because the numbers of males were more than girls , suggesting the errors in the reconstruction to make these categories led to the sudden rise . The scale of the UN Secretariat has exceeded the limit , which is where the old data type and is less accurate than (20) and occurred within the range which is where the age and type data are not accurate as the (34.2) . It could be argued that in general that all the measures referred to errors in the data age and type in the 1997 census , more than the limit . Following the revision of population data were later corrected by four methods , namely , (the distribution of the age group of others set out on the age groups , and the method of carrier and farrag , Carp method , Newton method , and the UN secretariat method the equation 16/1 ) . We found the best way to modify data on the population of Iraq was the way Carrier and farrag , where the scale of the Secretariat of the United Nations ( Accuracy Index) 21.72 , less derived values with others
