So this comment is going to be lengthy and mostly stream-of-consciousness type, but I really want people's opinions on things.
I'm working on the country Alta California from my "Balance of Power" ATL (see link in signature), and today specifically on the Chinese-Californian community, but I don't know much about the Chinese coimmunity in OTL California to use that as a jumping off point.
For stuff in the OTL 19th century, mentions of Chinese are mostly about things like the Page Act, the Chinese Exclusion Act, state & local laws about what jobs they can hold, ant-miscegenation laws but rarely about the community itself, prominent members, and so on. Though granted, when the commnity is 90% aging bachelors and the majority o fthem returned to China by WW1, "community" was likely a tenuous thing.
Prominent OTL Mexican Californios were mostly mestizos, few were criollos, and many even had some African ancestry like the final Mexican Governor Pio de Jésus Pico.
Just like OTL, 1848 Gold Rush immigrants from Chihuahua, Sonora, Peru, Chile, and Argentina were mostly mestizos themselves.
In this ATL, a better better economic situation in 1848 USA meant fewer Anglo-American gold rush settlers than OTL.
As a result, the largest ethno-linguistic bloc are the Spanish speakers and reinforced by a Spanish constitution, Spanish laws, Spanish becomes the lingua franca instead of English. Take the Anglo-European-Protestant default culture of Canada and the USA and imagine Alta California as an analog of that but Latino-Mestizo-Catholic in nature. (Except in the state of Deseret, but that's another story).
Because of that mestizo start, while racism still exists, it is muted compared to Canada and the USA, and even compared to Mexico. It's more about cultural assimilation than skin colour.
So in that milieu we have the Chinese emigrants.
In OTL 1890, 10% of California population were Chinese, but only 5% of them were women. Chinese women were seen as promiscuous, sexual threats to whiteness and spreaders of STDs and that racism was expressed in laws and regulations that restricted the ability of Chinese men to bring their wives & daughters with them long before the U.S.A.'s Chinese Exclusion Act of 1882. And because of that, following the passing of the ACE, many Chinese returned to China by WW1.
But since those OTL anti-Chinese laws of the USA don't exist in this ATL Alta California more Chines men can bring over their wives and daughters.
So now we have the following questions with respect to the Alta California Chinese community:
1. How many Chinese immigrant men bring over their wives to settle?
2. How many of the single Chinese men stay in Alta California instead of returning to China with their (relative) wealth?
3. How many of those single Chinese men marry the Chinese daughters of the Chinese men who brought their wives over?
4. How many of those single Chinese men marry Indigenous women or daughters of non-Chinese immigrants?
What effect does this have on the percentage of Chinese as part of the population of Alta California? Does it stay at the 10% of OTL 1890 California, or is it higher?
How many more Chinese women do we actually get coming over? Was their scarcity in OTL 1890 California really only due to the racist laws preventing immigration, or was Chinese cultural the actual big reason why so few Chinese women came over, and thus nothing would really change?
Do their Buddhist, Confucian, or Ancestor-worship religions prevent assimilation and intermarriage as an expression of the above-mentioned racism that does exist?
Or does that not matter and the kids just get raised as Catholic or Indigenous spirituality depending on whom the Chinese man married?
What does the Alta California 1890 Chinese community look like compared to OTL 1890 California?
What does the Alta California 1990 Chinese community look like compared to OTL 1990 California? Have the Chinese who've been there fora century completely assimilated like how the Germans, Italians, French, Irish, etc… have assimilated and like everybody has a Chinese great-great-great-grandfather or great-great-great-grandmother the same way everybody has an indigenous great-great-great-grandfather or great-great-great-grandmother?
How do you think this would all shake out?
