Zara's culture should probably be Northern Italian as it's likely more related to Venetian than to Tuscan,
Northern Transylvania's composition in 1940 was 50% Romanian and 37% Hungarian, it doesn't make much sense for it to be Hungarian.
The Catalan population in Eastern Aragon is nowhere near a majority
Maybe create Flemish and Wallon as separate from Dutch and French?
Hatay should probably be Syrian since Arabs, mostly Alawites and Sunni, formed the largest group followed by Turks according to a census in 1936

If I did not mention a state inside of africa, it is as accurate as I know it

State ID>culture it should be changed to

886>sudanese
887>darfur
840>Amhara
549>very diverse, but about 20% sudanese where other groups are less
885> Dinka
884>very diverse, but about 20% Nuer where other groups are less
550>Rename Eritrean to Tigrinya and make its color very close to Amharic as the cultures are closely related
842>Tigrinya (tigray did not exist because it came to existence when the Tigrinya that supported Ethiopia became Tigray and the Tigrinya that supported Eritrea kept Tigrinya)
903>Somali
838>Nuer with a large Kaffa minority
547> Kikuyu with heavy somali and Oromo minority
904> Kalenjin
905> Swahili
546> Very diverse, but swahili is good generalization that does not look to lazy
897> Makua
896> Very diverse, but Sena are the most numerous
544> Tsonga
770> Very diverse, but Chewa make up about 25% where other groups are less
545> Shona
542> Tswana
543> Malagasy
708> Coromo, very closely related to swahili, it would not be a crime to lump it with swahili
681> Rename Cape to Afrikaner
275> Sotho
719> Zulu
895> Herero make up about 40%, less than Ovambo, but the state should stay Herero because they make up about 20% of the state to the south and they should be represented.
541> Ovambo
894> Ovambo
893> Khoi
892> Ovimbundu
891> Chokwe, large Ganguela minority
540> Kongo
796> Kongo
539> Kongo, with a large Fang Minority
297> Fang
538> Mongo
888> Luba
771> Very Diverse, about 30% Bemba, the most of any group
889>luba
718>?????? belgium you suck
890> Rwanda(Which is why Rwanda keeps Invading DR Congo), divided between Hutu and Tutsi
768> Rwanda, divided between Hutu and Tutsi
769> Rundi, divided between Hutu and Tutsi
Rundi and Rwanda need to be similar colors because they are very similar.
548> Very Diverse, Baganda 16%, the most of any group
660> Very diverse, Gbaya about 1/3, most of any group
773> Very diverse, about 1/4 Bamileke, most of any group, Beti/Bass-Mbam are very close behind without 21%
900> Igbo
558> Yoruba
774> Very diverse, but about 40% Sara
775> Chadian Arab
515>Taureg
901> Kanuri
902> Fulani
776> Fon, with a large Yoruba minority
777> Very diverse, with about 22% Ewe, most of any group
274> Very Diverse, most common group is Akan
778> Mossi
779> Very Diverse, most common group is Akan
298> Liberian, But with a rapidly rising diverse native population that despises the richer and more educated Liberians that it will overthrow not long after Hoi4's timeline that ends in a genocide against them causing them to be forcefully assimilated into native groups. Liberia went from a Rich industrialised democracy to a poor dictatorship because of this.
700> Tenme with a heavy Mende minority
780> Split about equally between fulani, Susu, and Malinke
296> Very diverse, Balanta make up the most followed closely by fulani,
272> Very diverse, about a 1/3 Wolof, the most of any group
701> Very diverse, about a 1/3 Jahanka
899> About 50% Malinke and 45% Soninke
556> Bamabara
898> Songhai with a large Fulani minority
782> Taureg
557> Haratin

North Africa and middle East:
699> Saharawi Arab
514> Berber Arab
452> Libyan Arab
456> Sa'Idi Arab
457> Bedawi Arab
453> Bedawi Arab
553> Syrian Arab
799> Syrian Arab
680> Iraqi Arab(Yes, I know its in Syria, The euros made such horrible borders) with a large Kurdish Minority
413> Iraqi Arab
656> Iraqi Arab(Yes, Iraq is missing nearly half its historical territory)
859> Gulf Arab
756> Bahraini Arab, Since Qatar and Bahrain are in one state and Bahrain had a higher population at this time, Bahraini arab is this state's culture
856> Hedjazi Arab
855> Hedjazi Arab
679> Hedjazi Arab
659> Hadrami Arab
906> Soqotri Arab
Rename Levantine Arab to Najdi arab
All of these groups need to have Arab added on the end: Iraqi, Syrian, Omani, Yemeni, Moroccan, Algerian, Tunisian, Egyptian. They are all variations of the same ethnic group. Make sure their color is all similar on the map.

Small Other Edits:
420> Azeri
410> Baluchi (very similar to persian, make them close colors)
444> Baluchi
445> Baluchi, with a large Pashtun minority
415> Very Diverse, Very weak Hazara Majority and large pashtun minority
267> Very Diverse, about half Pashtun with a large Tajik minority
442> Pashtun
440> Panjabi
443> Sindhi
441> Kashmiri
787> Kashmiri
733> Bengali
432> Very diverse, Assamese majority
434> Tibetan, did not become become south asian until recently
752> Tibetan, did not become Chinese until the communist party attempted to eradicate the Tibetan people
604> Tibetan, did not become Chinese until the communist party attempted to eradicate the Tibetan people
655> Tibetan, did not become Chinese until the communist party attempted to eradicate the Tibetan people
746> Mongol, did not become Chinese until the communist party attempted to forcefully assimilate the Mongolian people.
761> Mongol(Mongolian refers to inhabitants of the country, Mongol is the people)
536> Yamato, Ainu were nearly eradicated by hoi4's timeline by various programs of the Japanese goverment and Hokkaido was Japanese by this time. Rename the Japanese group Yamato, Japanese refers to the people of the country and Yamato the ethnicity.
537> Yamato, see above
555> data is scarce, let them stay Ainu for now
526> Ryukyuan
574> Yakut

Strongly recommend changing all of China other than Xinjiang, tibet, inner mongolia, and the states mentioned before into a Han culture, which includes Taiwan and most of Manchuria, as the Manchus were nearly eradicated in a genocide carried out by the Nationalist Chinese and the warlords. But if you must keep the separate:
596> Wu Chinese
524> Min Chinese (Taiwanese were nearly killed out in Dutch and Manchu Genocides against them and are now and in Hoi4's timeline minorities in their homelands)
595> Min Chinese
591> Min Chinese
592>Yue Chinese
593>Yue Chinese
602> Xiang Chinese
Add all other states to a mandarin group, someone will get mad and fix the rest eventually.

Lastly:
Please rename Indigenous Brazilian to just Brazilian. The Indigenous Brazilians do not make a considerable minority anywhere at this time.
309>Guyanese, not a real thing, but is more appropriate than labeling it as Brazilian
310>Guyanese
687>Guyanses
494> Quechua. Yes the Inca people still exist, but their culture and language is completely ruined due to countless failed genocides, with one as recent as the 1990s.

Mapuche form a large and politically powerful minority in central-south Chile while not forming an outright majority in any of the states. Do what you wish with this information.

I will soon post an Update to the Mod. The mod is still far from finished, but i did some work an Africa, thanks to @Abyssinian Empire, who made it all possible.

The Update should now be live. Thanks @Abyssinian Empire, for your Help

Memel ( 188 ) at 1936 was majority german with a large lithuanian minority,
Vojvodina ( 45 ) at the time was majority hungarian with a large serb minority,
While both Stanislaw ( 89 ) and Lwow ( 91 ) were majority ukrainian but with a very large polish minority.
Vilnus/Wilno had a large polish minority ( 784)
North Transylvania was majority romanian but a good 40% were hungarians . (76)

Also why are random african states labled as yemeni? Gambia 701, portugese guinea 296, cameroon 773, benue 900, Mauritian desert 786, tombouctou 782, niger desert 515, and main niger 781. I mightve misspelled some of the names though.

Lastly, the guianas are listed as Brazilian, dispite them all being sorta culturally unique i think.
French guiana 310 would be culturally Guianese Creole ( a creole of french) while dutch suriname 309 would be Surinamese which is a mix of Maroons and "Indians" ( Hindustani ) with some creole influences. Lastly for the guianas British Guyana 687 would be culturally "Guyanese Creole" or "Gayiniiz" which is english creole with Indian and African Ethnic speakers.

Hey @DownUpLoader, i'll look into it and change it as soon as i find time, thanks!
Regarding Africa, its because i just absolutely dont know much abt the cultures there and couldnt find anything. but a Africa Rework is planned

@user030 Ight. I may go ahead and search for those african states in question and post what i find here, i could also look for the " No culture" states if you want as ive noticed a few of those.

@DownUpLoader, that'd be nice, thanks

Ive also noticed for Manchukuo it says the majority culture is "Korean" along with main korea being korean but with japanese influence. It could either go for "Manchu" or "Wu" dunno.

I might have some wrong province names, but the ID's should be correct.

FR - FRENCH BASED
PR - PORTUGESE BASED

hope this works!

Mb! For Kirin and Sungkiang it is majority Northeastern mandarin!

Yup, if you need anything else researched i can help

please try to add an option that culture may change. The sense is that if, for example, a province with Polish culture was occupied by Germany, after some time the culture would change to German
