I totally agree with you about the number of contributors in Europe versus in North America. But I don't see clear correlation between number of contributors and number of data (ways, nodes.....) because only 38% of contributors doesn't edit data, and only 19% make recuring edits. (source = http://www.mdpi.com/2220-9964/1/2/146) In the facts, most of main ways (coastlines, cities, roads, administrative boundaries....) provides from Datasets mentionned here ( http://wiki.openstreetmap.org/wiki/Import/Catalogue) But if you take the time to analyse this import catalog <http://wiki.openstreetmap.org/wiki/Import/Catalogue>, it's clear that *mostly all datasets are provided by European* organisations (*only 14%* from North-America). So, YES Europe has more date but MOSTLY because of import of dataset. *For sure, contributors maintained and enhanced acuracy of these data*... but nobody can imagine that every single house and every single road has been "handmade" by volunteered geographic information (VGI): In this context, if I "introduce new mappers to OpenStreetMap" as you said, *by telling them drawing manualy every single boundary administrative of*36 % of Canadian municipalities in province of Quebec (n = 1 348) : - 300 hamlets - 728 rural cities - 295 urban cities - 30 urbain agglomérations Wheather is good, sun is shining.... I'm not sure they will spend so much time by in fornt of theyr computer, clicking on their mouse to add so much nodes.... I'm not sure this is a "winner scenario" .... Well... all those figures strengthen my feeling that North-America doesn't like OpenData (14%) whereas Europe is very generous and "open-minded". Best regards,
