as a separate people group. In a 2011 census, it was discovered that nearly two-thirds of the nearly 12,500 Seto speaking population in Estonia lived outside the historically Seto regions. This resulted in two distinct communities of Setos to emerge according to research conducted by Pille Runnel, the first being the Seto who had migrated away from Setomaa and had to recreate a communal and religious identity.
