Here's the post and links:
"The article notes first that, of course, the evidence is flawed and incomplete; any estimate of maternal mortality from the 16th to 18th centuries cannot be any better than a very rough, error-riddled estimate. That said, here's what they found. In one parish in England, church registers counted 23.5 maternal deaths per thousand baptisms (so, per thousand births, assuming each birth results in a baptism). The London Bills of Mortality count an average of 15.9 maternal deaths per thousand baptisms from 1666 to 1758, not counting plague years. That's a maternal mortality rate comparable to that in modern Afghanistan. The paper notes that these are "certainly underestimates." For example, deaths from ectopic pregnancies or early miscarriage complications might not have been counted if they couldn't be recognized.
Continuing on, death rates in the mid-1800s were apparently lower, on the order of 5 maternal deaths per 1000 live births. That's a bit higher than Bangladesh's rates today. Odds of the mother dying were much higher when the baby was stillborn, ranging from 57 to 137 maternal deaths per 1000 stillbirths. That's as many as 13% of women dying while giving birth to a still baby. Sort of an intuitive result: unknown pregnancy complications, on which we can only speculate, mean a much higher chance of both maternal and fetal death.
Overall, the paper estimates about 25 deaths per 1000 live births from the 16th to 18th centuries. That's a 2.5% chance of death per birth, or 2500 in 100,000 live births. That's quite a bit higher than the rate in Afghanistan today, which is 1800 maternal days per 100,000 births. "
Those quotes from this blog which references the two papers the figures were from:

Estimate of length of Wars of the Roses: 30 years.
Estimate of overall death toll: 50,000
Estimate of population of England at the time: 3.5-5m.
Answer: a hell of a lot more women died in childbirth than men died in war in those 30 years.
