Identifying common sources of population heterogeneity

The World Population Program (POP), with three other IIASA programs—Energy (ENE), Mitigation of Air Pollution and Greenhouse Gases (MAG), and Ecosystems Services and Management (ESM), has begun to implement the crosscutting project “Accounting for socioeconomic heterogeneity in IIASA models.”

POP scientists’ role is to contribute scenarios on population heterogeneity that will include assumptions developed for the Shared Socioeconomic Pathways scenarios developed at IIASA for the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). POP will expand these through new bottom-up modeling of urban/rural place of residence for the case of India.

After extensive inter-program consultations, common sources of population heterogeneity were identified that are potentially important because of the differential behaviors contributing to their outcome. Currently, place of residence (rural/urban) and the level of income of the population are identified as two additional sources.

A literature analysis was conducted to support the assumed associations between quantifications of these heterogeneities and different IIASA model variables. The initial geographic focus of the project is South Asia, with the wider aim of going global by the end of the project.

POP researchers have already begun producing population distribution by age, sex, educational attainment, and rural/urban residence for India.
