Introduction

PolicyEngine-UK-Data is a package that creates representative microdata for the UK, designed for input in the PolicyEngine tax-benefit microsimulation model. This tool allows users to explore the data sources, validation processes, and enhancements made to ensure accurate and reliable microsimulation results.

PolicyEngine is a tool with a clear purpose: for given assumptions about UK government policy and UK households, predicting what UK households will look like in the next few years. To do that, we need both of two things:

• An accurate model of the effects of policy rules on households.

• An accurate representation of the current UK household sector now.

This repository is dedicated to the second of those. In this documentation, we’ll explain how we do that, but we’ll also use our model (the first bullet) to see what we end up with when we combine the two, and measure up against other organisations doing the same thing.
