USA: Spanish. I’m learning Spanish, and I think as a whole it’s like 18% of people in the USA but I feel like you’re likely to encounter some Spanish speakers and make friends even if not everyone speaks Spanish here.
Brazil: It looks like Spanish is also the second most spoken language with 4% or English with around 5%. I’m sure you’re more likely to find people on the Internet who speak it.
French: English, apparently a quarter of the population speak it??? Not sure how likely you are to find someone in the wild speaking it, but on the Internet, a lot of people.
Living in Ottawa, Canada and frequently visiting Montréal 😬. Ottawa is majority English, especially in the west end but it’s like a 30/70 split for French and English downtown and gets more and more French as you go east. By the eastern suburbs you’re hearing French most of the time
Canada as a whole is majority English but Québec is obviously primarily French. New Brunswick is significantly French as well and there are other pockets of other French areas scattered across the country
