The purpose of this notebook is to re-create the cohort-component forecasting methodology used in the 2045 forecasting effort using a programmatic approach. The approach used in 2045 was implemented in Excel. Because of this, it is more difficult to audit the approach and implement some of the more complex aspects such as age-specific birth rates at 5-year age increments.
