Dini E, Goldring S. Estimating the changing population of the 'oldest old'. Population Trends 2008; 132 (2): 8-16
The population of England and Wales is becoming older. This poses an increasing demand for detailed data on the size and trends of the population at the oldest ages. Using the recently released Office for National Statistics estimates of the population aged 90 and over in England and Wales, this article shows trends in the population of the oldest old and demographic causes of the rapid increase in centenarians during the twentieth century. It also presents further validation of the ONS estimates of the oldest old with estimates from other data sources.
