1. 1959-1961年“三年自然灾害”,确实是建国五十年来范围最大、程度最深、持续时间最长的最大自然灾害。
2. 1959-1961年,全国总死亡人口为3603万。
3. 已解密的美国中情局(CIA)1962年5月2日的绝密文件:“1961年中国的粮食产量可能少于1957年正常年分的粮食产量,但中国1961年的人口却比1957年增加了6000万人,结果是许多地方粮食不足,营养不良。。。。。。但并没有发生像过去旧中国常见的大饥荒。” The Chinese Communist regime is now facing the most serious economic difficulties it has confronted since it consolidated its power over mainland China. As a result of economic mismanagement, and, especially, of two years of unfavorable weather, food production in 1960 was little if any larger than in 1957—at which time there were about 50 million fewer Chinese to feed. Widespread famine does not appear to be at hand (大规模的饥馑似乎并没有发生)。
