Native language draw its last breath in the third generation of

I wonder if any study on Chinese immigrants like this, below. "Spanish appears to draw its last breath in the third generation" . That reminded me of German in 1950s - during WWII, flooding-in of German immigrants came to the US - some worried that Germans continuously used German, leading to a German-speaking country, remapping the horizon. Now, we see it didn't happen. How about Chinese?

Linguists have often referred to America as a “language graveyard”. Despite being a country of immigrants, it has tended to snuff out foreign languages within two or three generations. Spanish, it has long been thought, might be different. Hispanics account for 18% of America’s population and are projected to make up 28% by 2060, according to the United States Census Bureau. Given the large size and rapid growth of the Hispanic population, some people used to fear that Spanish would not only endure but overtake English, especially in states like California and New Mexico, where Latinos are the largest ethnic group.

That concern has turned out to be unfounded. Between 2006 and 2015 the population that speaks Spanish at home in America, which is often interpreted as a proxy for Spanish dominance, grew from 31m to 37m. But during the same period the share of all Spanish-speaking Hispanics who speak Spanish at home shrank by five percentage points, from 78% to 73%. Data analysed by Pew Research Centre, a think-tank, show that, in 2000, 48% of Latino adults aged 50 to 68 and 73% of Latino children aged 5 to 17 spoke “only English” or “English very well”. By 2014 those figures had increased to 52% and 88%."

Can Spanish avoid America's language graveyard? The Economist - March 28, 2018 In his well-known study on “linguistic life expectancies” in southern California in 2006, Ruben Rumbaut, a professor at the University of California, Irvine, found that Spanish was following the same trajectory as other languages in America had-just more slowly. He established that only 5% of fourth-generation Mexican-Americans in southern California could speak Spanish very well: “After at least 50 years of continuous Mexican migration into southern California, Spanish appears to draw its last breath in the third generation.” [Subscription required.]
