For day 2️⃣ 9️⃣ of #30DayMapChallenge I looked again at where Welsh is spoken in Wales. I did this a few years ago, but this time I used 2021 Census data as well as language medium of primary (ages 5-11) education. Result looks very similar to 6 years ago.
My Uncle researched historical Welsh isoglosses, so I include his map too.
