Analyst briefing

Slovenia: Small, Wealthy Euro-Area State With a Thin Defense Footprint

Slovenia's economy was valued at $72.97 billion in 2024, with GDP per capita of $34,301 and a population of 2,127,400, per World Bank WDI figures. The country sits well inside the European Union's institutional core, and its governance indicators reflect that: V-Dem's 2025 wave scores Slovenia at 0.692 on electoral democracy and 0.589 on liberal democracy, alongside a state capacity score of 0.9, among the higher readings in the V-Dem dataset's 0-1 range.

On defense, SIPRI's 2025 Milex data put Slovenian military expenditure at $1.22 billion, equivalent to 1.544 percent of GDP under SIPRI's own GDP series — a figure that should not be recalculated against the World Bank's separate GDP estimate above, since the two series are not interchangeable. The Correlates of War National Material Capabilities dataset recorded 6,000 active-duty personnel in 2022 and assigned Slovenia a Composite Index of National Capability (CINC) score of 0.00026487076 for the same year, a measure of relative share of global material power rather than an absolute capability metric.

Energy figures point to a small system: Our World in Data put Slovenia's primary energy consumption at 0.285 exajoules in 2024 and electricity generation at 14.84 terawatt-hours in 2025.

Fiscal Position

The IMF's World Economic Outlook projects government debt at 65.2 percent of GDP for 2026. IMF International Financial Statistics data recorded reserves of $2.96 billion for 2025.

Data Gaps

Oil and gas production figures from Our World in Data are both dated 2016 (0.003 TWh and 0.055 TWh respectively) and are stale by nearly a decade; they should not be read as current output. The 2026 government debt figure is an IMF projection rather than an outturn. No V-Dem or SIPRI series extend past 2025 in this bundle, and no conflict-event or alliance data are included here.
