These complications are actually similar for spontaneous abortions (also known as "miscarriages")
[i]Mortality and morbidity depend on gestational age at the time of miscarriage or abortion. In the United States, mortality rates per 100,000 abortions are as follows: fewer than 8 weeks, 0.5%; 11-12 weeks, 2.2%; 16-20 weeks, 14%; and more than 21 weeks, 18%.
Septic abortion remains a primary cause of maternal mortality in the developing world, mostly as a result of illegal abortions. Unsafe abortions account for nearly one half of abortions, and morbidity/mortality occurs particularly often women who live in developing nations.
According to the World Health Organization, about 68,000 women die each year due to complications from unsafe abortions, with sepsis as the main cause of death. In the United States in 2010 (the most recent year for which data were available), 10 women reportedly died from complications of legal induced abortion. There were no reports of deaths associated with known illegally induced abortions.
In the United States, mortality from septic abortion rapidly declined after legalization of abortion. Death now occurs in less than 1 per 100,000 abortions. Figures for most European countries are similar to US rates.
The risk of death from septic abortion rises with the progression of gestation.[/i]

And yes, I know we are all howling with laughter at the remark that "death now occurs in less than 1 per 100,000 abortions", as death actually occurs in 100,000 per 100,000 abortions, but I believe the writer means "death of the mother".
