demographic-analysis

What problem does it solve?

This Skill helps you perform core demographic methods—life table construction, mortality forecasting, and population projection—so you can quantify population dynamics and compare outcomes across groups or time.

Core Features & Use Cases

• Life table building and life expectancy: Convert age-specific death rates into life tables, including Chiang-style confidence intervals for e0.
• Population projection with Leslie matrices: Build a Leslie matrix from survival and fertility inputs and project population structure and growth.
• Mortality modeling and decomposition: Estimate the Lee–Carter mortality model via SVD and use Arriaga decomposition to explain differences in life expectancy between populations.

Quick Start

Tell an AI agent to construct a life table from your age-specific death rates and compute e0 with a confidence interval, then project a future population using a Leslie matrix and estimate a Lee–Carter mortality forecast from your historical mx data.
