Amplified Changes: An Analysis of Four Dynamic Fertility Modelsns behind each model provide insights into the forces that influence fertility. We present Ryder’s classic formulation of the translation between period and cohort measures of fertility, Lee’s moving-target model connecting fertility goals with period rates, the period-shift model of Bongaarts and F

Revisiting Life Expectancy Rankings in Countries that Have Experienced Fast Mortality Declinetages of using actual cohorts (as opposed to synthetic cohorts) for building life tables, but uses all the available mortality information up to the present. Specifically, for each non-extinct cohort present in the population at time ., we calculate the cohort’s truncated life expectancy at birth, w
