Heaping  (HEAPING)


It is often necessary to graduate distributions to correct the tendency of people to give their replies in round numbers1. This tendency is sometimes referred to as the heaping2 or bunching2 of replies at preferred points3, and indices of heaping4 or indices of bunching4 may be constructed. One of the major applications of this method in demography is the adjustment of age distributions, where there is a tendency for people to state their ages in numbers ending with 0, 5 or other preferred digits.
