Innovations in methodological approaches to estimate irregular migrant stocks and flows
Author
Description (eng)
Key points
• This chapter builds on Rodríguez-Sánchez and Tjaden (2023), who reviewed the main
methods for estimating irregular migrant stocks and flows, spanning both established and
more experimental approaches.
• Measuring irregular migration remains a fundamental challenge: the population is difficult
to observe, and even widely used methods such as residual estimation or capture–recapture
provide only partial pictures.
• Traditional techniques continue to form the backbone of the field, but improvements have
often come from incremental innovations, such as using mortality data to refine life-course
approaches, or expanding residual methods with large government databases and machine
learning.
• More novel directions, such as exploiting consular registers, driver’s licence data, or online
search behaviour, show promise in filling gaps, though these remain context-specific and
experimental.
