The European Colloquium on Theoretical and Quantitative Geography – ECTQG – is both a bi-annual scientific meeting and a community of scientists from all over Europe, who are interested in advancing quantitative methods and theories with a strong geographical dimension.

The first colloquium was held in 1978 in Strasbourg where 49 researchers from Britain, France, Austria and Germany discussed advances in spatial analysis, statistics, and spatial interactions, and conducted epistemological introspection about the quantitative turn in geography within their respective research traditions. Except for a small hiccup in the early 1980’s, the colloquium was held every second year since. The community quickly expanded to most European countries and beyond, and topics diversified with time.
