SimPaths Wiki

Welcome to the Wiki of the SimPaths project! For the web based version click here

This Wiki serves as the central hub for all documentation related to our project. Whether you are a new contributor, user, or just curious about what we are working on, you'll find useful information here.

SimPaths is an open-source framework for modelling individual and household life course events across multiple domains. The framework projects life histories over time, developing detailed representations of career paths, family and intergenerational relationships, health, and financial circumstances. As a family of models, SimPaths offers a dynamic simulation of how life events evolve and interact within populations. For a detailed description of the building blocks of the model, visit the Model structure page.

SimPaths builds upon JAS-mine, an open-source Java platform designed for discrete-event simulations. Useful resources on JAS-mine are collected in the Centre for Microsimulation and Policy Analysis website.

SimPaths models currently exist for the UK, Greece, Hungary, Italy, and Poland. This page refers to the UK model; the other European models are available at the corresponding SimPathsEU page.

Research based on SimPaths is rich and growing. See the full list of published and working papers in the Research page.


Outline

A list of references for SimPaths, including the SimPaths reference paper that users are requested to cite in their derived work.

All the basic information on SimPaths and the functionality provided by the model.

SimPaths runs with demo data. This section explains how to apply for input data representative of the UK population.

How to run the model though the GUI, modify parameters, create scenarios, and perform uncertainty analysis.

How the code is structured and how to modify it.

How to validate simulated outputs against real survey data.

How to make the best use of the embedded JAS-mine functionalities.

Step-by-step instructions from installing the environment to understanding the code structure and running SimPaths simulations.
