HEAD TO HEAD
Antigua and Barbuda vs St. Kitts and Nevis
Verdict
Antigua and Barbuda holds a 64–36 advantage over St. Kitts and Nevis on the Relative Advantage Index, a clear margin.
The margin is driven by economic size (GDP) (66% of the combined total, $2.2bn) and logistics & power projection (60% of the combined total, 3).
3 factors — military spending, active personnel, nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
