Finding unbiased numbers is hard, obviously. Maybe we'll know more about it 50 years from now, but at the moment our knowledge is approximately what it was for the Soviet Union right after Stalin's death or so, yes?
That said, I have yet to see anything resembling a credible source that claimed more than 10,000 direct deaths caused by the Castro regime. I've seen much higher numbers (50,000 or more) in terms of indirect deaths: people trying to get out of Cuba and drowning in the process.
The population of Cuba around the time of the revolution was about 7 million; now it's around 11 million. The population of the Soviet Union in the 1930s was between 150 and 200 million (good statistics are hard to come by; see https://en.wikipedia.org/wiki/Soviet_Census_(1937) for why). Even if we take the extreme 7 million and 200 million numbers, 10,000 Cuban deaths is equivalent to about 285,000 Soviet deaths on a per-capita basis. And that's over a 50-year or so period. So yes, Stalin killed a lot more people no matter how you count it. Of course, "leader who killed a smaller percentage of the population than Stalin" is a _really_ low bar; pretty much everyone except Pol Pot clears it.
In general, the "Cuba under Castro" numbers for political violence don't seem any worse than other Latin American countries in the 20th century. Again, this isn't _good_, just like it's not good that we can end up talking about "oh, that's equivalent to hundreds of thousands of deaths on a per-capita basis, which is _tiny_". :(
Under those indirect causalities the U.S. has killed millions! even its own population when they get sick and can't afford their drugs. My point is that Cuba under Castro was not -by far- like the Soviet Union under Stalin as some people believe.
10k over 50 years? Wow, that's a lot less than I imagined from how he is described as a mindless killer, and the dictatorship as drenched in blood.
For comparison Puerto Rico have had about 10k murders in the last 15 years alone[1], and that's in less than half the Cuban population.
From 1998 figures[2] and 2002 population numbers I guesstimate that officially about 820 murders occur per year in Cuba, and the 10k in 50 years evens out to 200 per year.
> Wow, that's a lot less than I imagined from how he is described as a mindless killer, and the dictatorship as drenched in blood.
Yep. Would it likewise surprise you to learn that the Pinochet government, which is described in similar ways, killed (at the high end of the estimates; the officially accepted ones are 10-20% lower) about 3200 people and "disappeared" about 1000, over the course of 17 years? Also, about 30,000 tortured, though; I have not seen claims of this for Castro's Cuba. All this out of a population of 10-13 million. It sure surprised me when I looked up the numbers.
I'm not condoning the things either government (Pinochet's or Castro's) did, but they are both nowhere close to being "drenched in blood" the way Stalin's or Pol Pot's or Mao's governments were.
Yeah, 4200 is way less than I expected from Pinochet's reputation. Works out about 50 % worse than Castro on murders alone (counting "disappeared" equally to other killings) on a per year basis. Not sure how to count the torture, maybe as fractions of a killing.
I'm also surprised that the population isn't more, Chile felt like a "big" country to me compared to tiny Sweden, but 11 is not much bigger than 8. Though by now it's 18 and 9 millions, so I child deaths seem to be down in Chile since the 80's.
