HEAD TO HEAD
Barbados vs Trinidad and Tobago
Verdict
Trinidad and Tobago holds a 80–20 advantage over Barbados on the Relative Advantage Index, a decisive margin.
The margin is driven by economic size (GDP) (77% of the combined total, $25.6bn) and active personnel (83% of the combined total, 5.0k).
2 factors — military spending, nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
