If you look in the methods section of the paper, it is based on surveys and a lot of extrapolation.
I am not sure how accurate their results are. Note also this statement: "Women, children (ie, younger than 18 years), and older people (ie, older than 64 years) comprised 56·2% (95% CI 50·4–61·9) of violent deaths". They do not mention what percentage of the total population these demographic groups represent (~77% of the total population), as that would show that 56.2% is heavily
underrepresented, meaning that adult men under 65 are heavily overrepresented. It also ignores the fact that Hamas and other terror groups routinely recruit minor teenagers. Therefore, 15-17 age cohort should have been examined separately from the 0-14 one.
