Welcome to MicroWELT!

MicroWELT is a dynamic microsimulation platform developed for the comparative study of the interactions between population aging, sociodemographic change, and welfare state regimes. It is used for a wide range of studies, including labor force projections, the impact of education, health, and ethnicity on the future labor force, the economic integration of immigrants, the sustainability and adequacy of social security systems, and private and public social transfers (time and money) according to the National Transfer Accounting (NTA) framework. Applications are available for many countries of the European Union, the United Kingdom, the United States, and Canada.

MicroWELT is a portable continuous-time interacting population model based on readily available data for many countries. Its sister model, microDEMS, is a refined Austrian version built on the same platform but based on detailed longitudinal administrative records.

MicroWELT is fully documented and designed as a modular platform that can be refined and extended for a wide range of applications. The development of MicroWELT is led by the Austrian Institute of Economic Research (WIFO) alongside international and national research programs.
