How many words are there in Tanach? already asks about several statistics about Sifrei Tanach, but there's one that was left out:
How many Parshios are in each Sefer of Tanach?
A Parsha is defined as all the text between one gap in a Sefer Torah and the next, whether that gap is a 9-letter space ("setumah"), continues until the end of the line ("pesuchah"), or is the end of the Sefer.
I'm aware that there are different Minhagim on the matter; I'd be curious to see all of the major ones.
