Tyumen Oblast is small region in Western Siberia. It has total area about 160 000 square kilometres and population about 1 340 000 (308 persons (or 0.02%) are OSM contributors).
Years and years ago first human settlement was marked on OpenStreetMap in Tyumen Oblast. It was Tyumen (was added by contributor LA2). This event happened in 2007.
Many local contributors improved OpenStreetMap after it.
Year is a year when an account was created.
Probably, these contributors live in Tyumen Oblast because they usually edit in this area. Of course, some contributors of other regions improve OpenStreetMap in this area also.
Since 2016 there are local maps.me contributors.
Maps.me contributor is a contributor who created first changeset/note using maps.me program. One contributor created his account in 2011 but he created his first changeset in 2016.
Many local contributors (64%) usually edit Tyumen’s map. Tyumen is a regional capital with population about 720 000. Tyumen city’s population amounts to about 54% of Tyumen Oblast’s population.
Tyumen Oblast has 2 cities, 3 towns and about 1200 villages. Now OpenStreetMap contains all these human settlements as nodes (or in more details). It’s a good result.
