Abstract
The collection of data by public and private organisations has increased rapidly and continuously in the last decades. While some have called for “the end of theory” in a society dominated by data, this paper argues that theory and data driven approaches are both fundamental to make informed evidence-based decisions.
Taking the case of geographic data products aimed at supporting urban planning, this paper critically examines the approaches that underpin their development. Through illustrative examples, it describes two types of research data products — small-area multidimensional theory-driven indicators and data-driven classifications — and outlines their respective advantages, limitations, and applications.
While it is recognised that geographic data products can be a valuable asset to support urban planning, challenges remain in translating research outputs into practice. To avoid technocratic and decontextualised applications of such data, it is suggested to prioritise reflexivity, situate knowledge, acknowledge uncertainty, and embrace openness throughout the data production and use process.
