cohortcomponent
The cohort-component method, also known as the cohort-component model, is a demographic projection technique that models population change by age and sex through separate components of change: births, deaths, and international migration. It follows cohorts as they age over time, applying survival to move them forward and incorporating new entrants in the youngest ages from births and migration.
Inputs for the method include the initial population by age and sex, age-specific fertility rates, mortality
The projection process works as follows: for each time step, births are computed by multiplying the number
Uses and limitations: the method is widely employed in national and subnational population projections, planning, and
