Differences in life expectancy between various countries of Latin America decreased considerably between 1960 and 1979. More recently, this decrease has slowed down in the 1980s. Disparities between Latin American countries remain considerable. Indeed, some countries are near European standards, others are more similar to some countries of sub-Saharan Africa with low life expectancy. Statistical analysis has demonstrated that after 1960, disparities are associated with economic factors, life expectancy is lower than 64 years; with cultural factors life expectancy is higher. According to the results of a factoral analysis, it is possible to classify countries into six groups with regard to life expectancy.
1960年至1979年间，拉丁美洲各国的预期寿命差异大幅缩小。最近，这种下降在20世纪80年代有所放缓。拉丁美洲国家之间的差距仍然很大。事实上，一些国家接近欧洲标准，另一些国家则更类似于撒哈拉以南非洲一些预期寿命较低的国家。统计分析表明，1960年以后，差距与经济因素有关，预期寿命低于64岁；与文化因素有关时，预期寿命较高。根据因子分析的结果，就预期寿命而言，可以将各国分为六组。
