2008 was the third consecutive year of population decline in Cuba.
ONE reported that 37,000 Cubans emigrated. They recorded 10,000 births and 86,000 deaths (a record since 1963, when ONE started these reports).
By the year 2020, ONE expects Cuba's population to be 25,000 less than it was in 2008. I don't quite know how they reach that figure, since it seems like in just one year Cuba might have 25,000 people less than they did in 2008. Maybe they'll just start counting the tourists.
According to CEPAL, Cuba is the only country in the region that has a negative growth rate...it's just another one of the successes of the Revolution.
