Varying definitions of both make it difficult to compare research or draw clear policy conclusions. • Both irregular migration and informal work are hard to measure. This makes it especially difficult to accurately assess how they intersect. • This chapter presents a straightforward, flexible and scalable framework for estimating this overlap. Using data sources commonly available in many countries, it can generate plausible ranges for the number of irregular migrants working in the informal economy.
