Population Submodel

The population submodel uses an integrated systems approach, in which the results of the fertility and mortality submodels are structured into pressure, state, impact and response (P-S-I-R) modules: 

• A pressure module describing the health determinants, which are divided into both socio-economic factors (income and literacy status) and environmental factors (food and water availability, malaria risk).
• A state module simulating fertility behaviour and population dynamics for disease and disease-specific mortality; both of these serve as input to the population module distinguishing sex and age groups.
• An impact module describing the quantitative and qualitative aspects of the state module, such as the burden of disease and life expectancy, and the size and structure of the population.
• A response module consisting of population policies influencing the fertility behaviour and health policies influencing the disease processes.
