On 31 January 2018, there were 27,675 non-governmental organisations registered in Slovenia, of which 24,169 societies, 3250 (private) institutes and 256 institutions. In comparison, there were 17 more than on 31 December 2017, when there were 27,658 organisations, of which 24,160 societies, 3,239 (private) institutes and 259 institutions.
In recent years, the number of NGOs has been growing by around 620 per year. Registered on 17 September 2012 were 22,490 societies, 2,324 institutes and 251 institutions. Not all registered NGOs are necessarily active. In compliance with the established practice, active organisations are those submitting their annual reports to AJPES, which is ca. 4% less than the number of registered organisations. The data on active NGOs is only accessible for previous years and likely to be available each July when AJPES has processed aggregated data on submitted annual reports. In 2016, there were just below 26,500 active societies, institutes and institutions.
The data on societies also comprise data on society branches and youth councils, and data on institutes comprise data on religious communities having the humanitarian organisation status. The data excludes the societies, institutes and institutions that have been established by the Republic of Slovenia, municipalities or other public sector entities.
