I have just finished fixing the POP of the world number wise. I adjusted religion a bit here and there as well.
Basically this lowered India, China, The Ottomans (Syria, Iraq, Anatolia, & Bulgaria), Persia, Crete, Cyprus, Palestine & Trans-Jordan, French Guyanna, Ireland and Tunisia.
I have increased population in Algeria and Morocco.
edit: many, many other changes have been added & fixed. Most of this is not in the VIP or POP mod for reasons unknown to me.
If anyone would like my POP mod email me at: firstname.lastname@example.org
