Forecasting Life Expectancy: The SCOPE Approachopes” out the range of possibilities the future may hold. I first described this SCOPE method at a workshop organized by Juha Alho several years ago in Finland. It is a kind of scenario method – with probabilities attached to scenarios, with scenarios structured conditionally, and with the possibili

Figure 9.1 shows that the calculations made in the 1980s were much closer to the current estimate than those published around 1990. Subsequent forecasts for t

Remarks on the Use of Probabilities in Demography and Forecasting texts on demographic methods (., Shryock and Siegel 1976), variance in the number of survivors plays no role. Similarly, concepts of estimation, estimation error, and bias are routinely used, but standard error and sampling distribution are not (except in connection with sample surveys). Although s

An Expert Knowledge Approach to Stochastic Mortality Forecasting in the Netherlands Netherlands up to 2050. The forecasts are based on assumptions about future changes in fertility, mortality, and international migration. Obviously, the validity of assumptions on changes in the long run is uncertain, even if the assumptions are expected to describe the expected future according to

Stochastic Forecasts of Mortality, Population and Pension Systemsension funds. The method of mortality analysis was developed by Lee and Carter (1992), henceforth called the LC method. Lee and Tuljapurkar (1994) combined the LC method with a related fertility forecast to make stochastic population forecasts for the US. Tuljapurkar and Lee (1999) and Lee and Tulja
