Model options, relationships, and uses

Demographic model options	Relationships	Uses
Single region cohort survival (SRCS)	Fertility rates fall with increasing education Mortality rates fall with increasing education Migration rates increase with increasing education	Independent forecasts for a set of country or region or group populations
Multiregional cohort survival (MRCS)	Forecasts of prevalence levels for education are driven mainly by cohort replacement at ages 30 years and over, by educational investment at ages less than 30 years	Aligned forecasts for a set of regions or countries, linked through migration flows/rates
Biregional cohort survival (BRCS)	Forecasts of labor force status and productivity dependent on education forecasts	Reduced version of the MRCS model applied when region or country sets are large
Microsimulation model (MSM) based on microdata from large survey or census	Simulates changes in person and household attributes for individuals	Provides scaled-up forecasts for the whole population
