> Flexurba is an open-source R package to flexibly reconstruct the Degree of Urbanisation (DEGURBA) classification. DEGURBA is an operational definition of cities, towns and rural areas that is widely used in policy reports and academic circles. It is developed by six international organisations - among which the European Commission and the OECD - to provide a globally consistent delineation of urban areas and thus enhance statistical comparability across nations. Much effort has been devoted to making the workflow behind the methodology as transparent and reproducible as possible: it is extensively documented in a manual (Eurostat, 2021) and a set of analytical tools is provided by the Global Human Settlement Layer to reproduce the classification. The current suite of tools uses a graphical user interface. This certainly enhances the ease of use, but also obscures the underlying code and restricts the user from adapting implementation details in the algorithm.

The package encompasses the first open implementation of DEGURBA's algorithm in any programming language. It provides flexibility to the user to customise the parameters in the algorithm and evaluate the consequences of certain implementation choices. The user can construct alternative versions of DEGURBA by changing the minimum population thresholds, and even more 'hidden' implementation details, such as the contiguity requirements and edge smoothing rules.
