Note: Estimates were made in the age interval 88–106 years for 10 single-year U.S. birth cohorts and data of enhanced accuracy for individuals who applied for Social Security numbers in the Northern states (see explanation in the text). Cases when the Gompertz model fits data better than the logistic model are highlighted in bold.
