This paper examined the accuracy of age-sex data reported in the Namibia population censuses with the aim to establish patterns and trends in the quality of age-sex reporting. The study followed a cross-sectional study design using the 1991, 2001 and 2011 population censuses data from Namibia Statistics Agency. We computed Whipple?s and Myers?s Blended indexes to measure age heaping. The age-sex ratio and UN joint score were used to ascertain the possibility of population undercounts and displacement between age groups. The analysis of single-age distribution showed a minimal digit preference across all three censuses. Likewise, Myers blended index portrayed that terminal digits 0, 1, 2, 5, 8 and 9 were preferred the most in all censuses. The Whipple?s Index showed a two-point decline suggesting an improvement in age reporting. The UN joint score found that the data collected in all three censuses were inaccurate in terms of age-sex displacement.
