But you can see what happened.

10k men killed out of 35k (identified).

11k unidentified, 14k identified non-men.

Assume all unidentified are not men:

7800*25k/14k = 14k (old number)

(5000 + some fraction of 1900) * 25k/14k = >9.5k (old number)

What they did was switch from assuming unidentified people were not men, to not making any assumptions and having a separate "unidentified" category.
