Quality evaluation of Spanish mortality statistics at advanced ages

The goal of this paper is to evaluate the quality of Spanish mortality statistics at advanced ages (70+) from 1910 to 2014. With data from INE and Human Mortality Database, we built two types of quality indicators: age heaping and age overstatement. Our results show that quality of Spanish mortality data at advanced ages improves throughout the 20th century. In the decade of the eighties, errors are minimized by modernization and by progress in data collection at the civil register
