Environmental Epidemiology and Toxicology

Perhaps someone can educate me on basic math here: if 424 deaths represent a
rate of 9.5 deaths per 1000 births, then there were 4,028 births in the area
and time period of interest, right? But if there were 271 fetal deaths,
which is given as a rate of 6.1 deaths per 1000 births, there must have been
1,653 births. How can this be?

Basic math lesson:

424 deaths at a rate of 9.5 deaths per 1000 births yields about 44,000 births
271 deaths at a rate of 6.1 deaths per 1000 births also yields about 44,000
births.

Since you asked...
