Demography & Population Studies

The statistical study of human populations — age-sex population pyramids, actuarial life tables, migration flow models, fertility rate dynamics, and the demographic transition from high to low birth and death rates.

Demography is the scientific study of human population structure and change. By analyzing birth rates, death rates, migration flows, and age distributions, demographers model how societies grow, age, and transform. These patterns shape everything from pension systems to housing markets, making demographic analysis essential for policy, economics, and public health.

These simulations let you build and animate population pyramids, compute survival probabilities from life tables, model migration push-pull dynamics, project fertility rate trends, and visualize the demographic transition — all with real-time parameter controls grounded in established demographic methods.

5 interactive simulations

simulator

Demographic Transition Model

Simulate the demographic transition — explore how development stage, healthcare access, industrialization, and urbanization drive the shift from high to low birth and death rates

simulator

Fertility Rate & Replacement Level

Simulate total fertility rate dynamics — explore how desired family size, contraception prevalence, female education, and child mortality affect TFR and replacement thresholds

simulator

Life Table & Survival Analysis

Simulate actuarial life tables — explore how infant mortality, adult mortality hazard, maximum lifespan, and initial cohort size shape survival curves and life expectancy

simulator

Migration Flow & Push-Pull Model

Simulate migration flows between regions — explore how wage differential, distance, origin population, and border friction govern migration rates using the gravity model

simulator

Population Pyramid & Age-Sex Distribution

Simulate population pyramids — explore how birth rate, death rate, growth rate, and migration shape the age-sex structure of a population over time
