UKMOD

Open-source tax-benefit microsimulation model for the UK you can trust

UKMOD is the only UK tax-benefit model that is truly accessible to everyone, where both the model and the underlying data are available free of charge. Developed and maintained over more than 20 years, with a lively community of users within academia, institutions and the third sector, UKMOD allows the creation and analysis of countless counterfactual scenarios for past, present and future years. Summary statistics illustrate results for different regions of the UK and bespoke individual profiles, while access to the micro-data and step-by-step explanation of how such data is created guarantees quality and transparency. And for those who do not wish to download the model and the data, an online version provides basic functionalities.

Key features

UKMOD permits analysis of the effects of taxes and social benefits on household incomes and work incentives for the population of each nation in the UK, as well as user-defined individual profiles. It is unique as it features great flexibility in the scope of its simulations and ensures cross-country consistency of the modelling approach and comparability of the results with the EUROMOD-based tax-benefit models for the EU Member States.

Resources

One model, four countries

Separate policy systems for each of the UK’s constituent nations allow the user to focus on Scotland, Wales, Northern Ireland or England, as well as the UK as a whole. Regional models (e.g. for Greater Essex) are also available, with reweighted datasets to ensure representativeness at the district level.

UKMOD is an open source project and is developed jointly with the Alliance for Microsimulation and Policy Analysis CIC.
