English has had a genocidal affect on the other languages spoken here, but many non-English languages still survive and some are quite thriving.
Pennsylvania Dutch is still quite alive with 300,000 native speakers. I think is is just a dialect of Rhenish German. It’s actually two separate languages and they can’t understand each other.
There are many other languages in the US that have been taken out by English. Most of the Indian languages spoken here have been driven extinct or moribund by English. A few like Cherokee, Sioux, Navajo, Mohawk, Pueblo, some Alaskan languages, a couple of Indian languages of the US South, are still doing well.
Most of the others are in bad to very bad shape, often moribund with only 10 or fewer speakers, often elderly. Many others are extinct. However, quite a few of these languages have had a small number of middle aged to elderly speakers for the last 25 years, so the situation is somewhat stable at least at the moment.
Almost all Indian languages are not being learned by children. But there are still children being raised speaking Cherokee, Navajo, Pueblo, Mohawk, and some Alaskan and Southern US Indian languages. Navajo is so difficult that when Navajo children show up at school, they still have problems with Navajo. They often don’t get the language in full until they are twelve.
However, there are revitalization efforts going on with many to most Indian languages, with varying amounts of success. Some are developing quite competent native speakers, often young people who learn the language starting at 18-20. I know that Wikchamni Yokuts has a new native speaker, a 23 year old man who learned from an old who is a native speaker. In California, there is a master apprentice program going on along these lines.
There are a number of preschool programs where elders try to teach the languages to young children. I am not sure how well they are working. There are problems with funding, orthographies and mostly apathy that are getting in the way of a lot of these programs.
There are many semi-speakers. For instance in the tribe I worked with, many of the Indians knew at least a few words, and some of the leadership knew quite a few words. But they could hardly make a sentence.
Eskimo-Aleut languages are still widely spoken in Alaska. I know that Inuktitut is still spoken, and there are children being raised in the language. Aleut is in poor shape.
Hawaiian was almost driven extinct but it was revived with a revitalization program. I understand that the language still has problems. I believe that there are Hawaiian medium schools that you can send your child to. There may be only ~10,000 fluent speakers but there are many more second language speakers with varying fluency.
There are actually some European based languages and creoles spoken in the US. A noncontroversial one is Gullah, spoken on the islands of South Carolina. There may be less than 5,000 speakers, but the situation has been stable for 30-35 years. Speakers are all Black. It is an English creole and it is not intelligible with English at all.
There is at least one form of French creole spoken in Louisiana. There is also an archaic form of French Proper called Continental French that resembles French from 1800. It has 2,000 speakers. Louisiana French Creole still has ~50,000 speakers. People worry about it but it has been stable for a long time. Many of the speakers are Black.
Texas German is really just a dialect of German spoken in Texas. There are only a few elderly speakers left.
There are a few Croatian languages spoken in the US that have diverged dramatically from the languages back home that they are now different languages. The status of these languages vary. Some are in good shape and others are almost dead. One of these is called Strawberry Hill Gorski Kotar Kaikavian spoken in Missouri. It is absolutely a full separate language and is no longer intelligible with the Gorski Kotar Kaikavian spoken back home.
There are other European languages spoken in the US, but they are not separate from those back home. Most are going out.
There are many Mandarin and especially Cantonese speakers in the US.
There are many Korean speakers in the US, especially in California.
There are a fair number of Japanese speakers in the US, mostly in California.
There are many speakers of Khmer, Lao, Hmong, and Vietnamese in the US. Most are in California but there are Hmong speakers in Minnesota also.
There are quite a few speakers of Arabic languages in the US. Yemeni, Syrian, and Palestinian Arabic are widely spoken. There are many in New York City, Michigan and California.
There are also some Assyrian speakers in the US and there are still children being raised in Assyrian. Most are in California.
There are quite a few Punjabi and Gujarati speakers in the US now. We have many Punjabi speakers in my city.
There are quite a few Urdu speakers here. Most of all of these speakers are in California.
Obviously there are many Spanish speakers in the US. English is definitely not taking out Spanish. They are mostly in the Southwest, Florida, and New York City, but they are spreading out all across the country now.
There are a few Portuguese speakers in the US. All also speak English. They are mostly in California but some are back east around Massachusetts.
The Sicilian Italian spoken in the US by Italian immigrants is still spoken fairly widely to this day. It has diverged so much from the Sicilian back home that when they go back to Sicily, they are not understood. This is mostly spoken in large cities back east.
There are quite a few Armenian speakers in the US and children are still being raised in Armenian. Most are in California.
There are some Persian speakers in the US, but not a lot. Most of these are in California too.
All of these languages are the same languages as spoken back home.
