OpenStreetMap participant OpenStreetMap contributors
Contributors
The project has a geographically diverse user-base, due to emphasis of local knowledge and "on-the-ground" situation in the process of data collection. Many early contributors were cyclists who survey with and for bicyclists, charting cycleroutes and navigable trails. Others are GIS professionals who contribute data with an extension for ArcGIS. Contributors are predominately men, with only 3–5% being women.By August 2008, shortly after the second The State of the Map conference was held, there were over 50,000 registered contributors; by March 2009, there were 100,000 and by the end of 2009 the figure was nearly 200,000. In April 2012, OpenStreetMap cleared 600,000 registered contributors. On 6 January 2013, OpenStreetMap reached one million registered users. Around 30% of users have contributed at least one point to the OpenStreetMap database.Since 2007, the OpenStreetMap community has held an annual, international conference called State of the Map. There are also various national, regional and continental SotM conferences, such as SotM U.S., SotM Baltics, SotM Asia & SotM Africa.As per a study conducted in 2011, only 38%  of members carried out at least one edit and  only 5% of members created more than 1000 nodes. Most members are in Europe (72%).
