Abstract: To evaluate the erroneous age reporting, there are several demographic methods available depending upon the type of age data. For example, in the case of single year of age data, some of the most commonly used measures in literature are the Whipple index, Myers index, Bachi index, and modified Whipple indices. This paper proposes a new modification of the Karup–King–Newton index as a general measure to check the quality of age distortion. When we compare the modified Karup–King–Newton index to the original index, it appears to be more adequate in terms of the estimation objective. Also, the proposed index is based on the same linearity assumption and practically gives the same result and direction as the original Karup–King–Newton index.
