What? This was an American vessel (registered in Florida) attacking what is essentially the Cuban coast guard. While it may have something to do with drugs or human trafficking, it could also be a botched US provocation op. What I don't see is what this has to do with people leaving Cuba.
Also that 25%, even as the high end of a potential range, is absurd. A quarter of the population of Cuba (~3 million) gone? Cuba's population is dropping, including but not solely due to immigration, with a 10% drop since 2020 being a reasonable estimate. 25% over the last 3 or 4 is not.
First of all, if you have to go back to 2012, then you're not dealing with "a few years," it's a decade and a half ago. And 13 to 14% over that time is still a far cry from 25%. From 11.3 million in 2015 to 9.75 million in 2024 is a 13.7% drop so from either 2012 or 2015, it's still in the 12-13% range. But that's not even necessarily the biggest issue.
Not only does that imply a much shorter timespan than the actual years being referenced, it implies that it's all the result of immigration which is wrong. Those population numbers are not limited to "lots of people [who have] left Cuba," but all the other reasons populations can decline, like simple birthrates being lower than deathrates which is a significantfactor in the ONEI estimates.
Again, 13-14% is not 25% but even so, that's still hyperbole. A quick search shows that Bulgaria and Latvia both saw steeper peacetime drops recently and those are just examples.
I don't think this really merits further argument but I do think it is worth calling out this kind of hyperbole and exaggeration.
