Serbia holds a 82–18 advantage over North Macedonia on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (88% of the combined total, $2.8bn) and economic size (GDP) (84% of the combined total, $90.1bn).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side. Those factors are excluded and the remaining weights renormalised, never substituted.
