| Annotation | The population in New Zealand, as in many other countries, is ageing, and the proportion of the oldest old (85 years and over) is increasing. Because of their smaller numbers and relative inaccessibility, the health status of this population has sometimes been extrapolated from populations of people aged 65 to 84 years. For people aged 65 to 84 years an exponential relationship is seen between age and morbidity and mortality. This study examined whether this exponential relationship extends to people aged 90 years and over. Data from the New Zealand 1991 Census and 1992 hospital discharge records were analysed, and an exponential relationship between age and mortality, inactivity, hospital utilisation, and occupation of residential institution was confirmed. This exponential trend did not continue for people aged 90 years and over for whom mortality rates and indicators of morbidity were considerably lower than expected, and indicate that the actual health status of people aged 90 years and over is better than the status extrapolated from that of people aged 60 to 89 years.
