CONSISTENCY OF AGE REPORTING ON DEATH CERTIFICATES AND SOCIAL-SECURITY RECORDS AMONG ELDERLY AFRICAN-AMERICANS

This paper investigates the quality of age data among African American s in two sets of government documents extensively used to study health and mortality among the elderly in the United States, namely vital st atistics and Medicare/Social Security data. The analyses reveal signif icant inconsistencies in age reporting in the two sources. A linkage o f records to a third data source, the U.S. Censuses of 1900, 1910, and 1920, reveals that Social Security data provide a superior source of age information among elderly African Americans, although the quality of data at the highest ages in this source is also suspect. Analyses o f factors associated with consistency of age reporting in the two sour ces identify birth record availability and literacy to be key influenc es. The authors conclude that studies involving elderly African Americ ans should institute independent age verification procedures at the ba seline interview in order to draw accurate conclusions about age-relat ed processes among this population subgroup.
