This is crucial. It cannot be done in the US, because this linkage is not done. If a woman were to get an abortion and die, it would be recorded as a death due to sepsis. The abortion would not be included in their medical history. It becomes impossible for medical researchers to do an accurate study of this question, at least in the US and Canada. Hence, Finland.

"the mortality rate associated with abortion is 2.95 times higher than that associated with pregnancies carried to term. The study included the entire population of women 15 to 49 years of age in Finland between 1987 and 2000. The researchers linked birth and abortion records to death certificates."
