Description: Mortality in the U.S. states at ages 80 and older and over years 1959–2011 analyzed and compared with mortality levels in 13 high-longevity countries.

Description: Demographers have typically viewed mortality trends from historical and cross-national perspectives, looking at commonalities in the evolution of mortality. In general, with improving economic conditions mortality has tended to decline and life expectancies to rise. The epidemiological transition from a mortality pattern dominated by infectious diseases to one in which more endogenous causes of death predominate is a central theme.

Description: Because data quality is critical in the measurement of an event as rare as the death of a supercentenarian, special care must be used. We will discuss practical methods of validation used by researchers in the field, alternate methodologies and data cleaning procedures to ensure validity of mortality data as extreme old age. We will also explore some of the consequences of inadequate data preparations on the curve of mortality at the end of life.
