On 31 August 2020, there were 27,996 non-governmental organisations registered in Slovenia, of which 24,085 were associations, 3,648 (private) institutes and 263 foundations. In comparison, there were 12 less than on 31 July 2020, when there were 28,008 organisations, of which 24,110were associations, 3,638 (private) institutes and 260 foundations.
In recent years, the number of NGOs has been growing by around 500 per year. Registered on 17 September 2012 were 22,490 associations, 2,324 institutes and 251 foundations. 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 cca. 3 % 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 2018, there were just below 27,000 active associations, institutes and foundations.
The data on associations 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 exclude the associations, institutes and foundations that have been established by the Republic of Slovenia, municipalities or other public sector entities.
