Wiki描述西藏时说:“Infant mortality has dropped from 43% in 1950 to 0.661% in 2000, life expectancy has risen from 35.5 years in 1950 to 67 in 2000”(
http://en.wikipedia.org/wiki/Tibet)
BBC 『A Year In Tibet』第三集16分前后这样描述:Tibet has the lowest life expectancy of anywhere in China, and one in three babies die before their first birthday. (该片描述的是2006年的西藏)
Infant mortality的定义是:the number of deaths of infants (one year of age or younger) per 1000 live births.
我觉得BBC的这个三个中有一个婴儿早于一岁死亡的说法欠妥,哪里有这么高的婴儿死亡率,大家认为呢?
