What does Big Data mean to public affairs research? Understanding the methodological and analytical challenges

The term ‘Big Data’ is often misunderstood or poorly defined, especially in the public sector. Ines Mergel, R. Karl Rethemeyer, and Kimberley R. Isett provide a definition that adequately encompasses the scale, collection processes, and sources of Big Data. However, while recognising its immense potential it is also important to consider the limitations when using Big Data as a policymaking tool. Using this data for purposes not previously envisioned can be problematic, researchers may encounter ethical issues, and certain demographics are often not captured or represented.
