The Pardee Center has completed Stage 1 of its two-year forecasting project for the SENS Foundation, a nonprofit organization that researches regenerative medicine solutions for the diseases and disabilities of aging. The project is exploring possible future trends in a world where regenerative medicine could extend, and possibly double, human lifespans. For this stage of the project, the team enhanced the International Futures demographics model to support life expectancies of up to 200 years of age. This required adding support for age-cohorts above 100+, new parameters and controls, and also changes in how IFs calculates mortality rates. In addition, the team has created a series of scenarios looking at different levels and rates of life-extension, along with changes in fertility patterns. All of these changes have been included in a new packaged version of IFs, created specifically for the SENS Foundation.
