ORIGINAL: tazzygirl how do you figure a 0.4%? im curious For illustrative purposes, I grabbed the CDC's 2005 data on births and infant mortality. In 2005, we had 4,138,573 "live births", as the US defines them. Of those, we had 28,384 infant deaths (18,782 neonatal deaths and 9,602 post-neonatal deaths). A neonatal death is any death within the first 28 days. Assuming EVERY ONE of those 18,782 children was specifically a stillborn preemie that only took a single heartbeat, we get a maximum of 18,782 "miscounted" deaths weighing down 4,119,793 "live births". If those 4,119,793 new souls lived out their statistically expected lifespans, then their average life expectancy would be N, computed as (total years lived) / 4,119,793. However, if we throw in an extra 18,782 "near-stillbirths", that drags the life expectancy down somewhat. The new value becomes N1=(total years lived) / 4,138,573 - and remember, each of them lived 0 years, so they contribute nothing to the "total years lived" value. So, the new value is off from the old value by a factor of 4,119,793/4,138,573 - N1 is 99.6% of N. Put another way, N1 is [18,782/4,138,573] less than N, which is 0.4%. That's given 2005's data. Given that infant mortality has gone down by "up to" 20%, and it's mathematically possible (although highly implausible) that every single one of those saved babies was ALSO a near-stillbirth, it's conceivable that we're looking at 0.5% instead of 0.4% - but even so, that's just an extra month out of 70-odd years.
