Converting that top 10 from the first pictures into percentages of the world population:
- 1996: 2.6/5.8 = 45%
- 2025: 3.1/8.2 = 38%
This decrease from 45% to 38% is actually good news, in my opinion. It means higher language diversity.
For the second picture, the interesting part is to contrast it with the first one:
- the L1 English speaking community is less than a half the L1 Mandarin one, but the former has a considerably larger non-native speaking community
- Hindi 345m vs. 609m might look like a surprise, but it's actually understandable, given the linguistic landscape of India. I expect most L2+ Hindi speakers to speak natively another language from India, too.
Picture #3 is interesting for potential diversity hotspots, but it should be taken with a grain of salt. Deciding what counts as a separated language is surprisingly hard; specially when language continua are involved. Also, it's understandably biased towards countries that control larger populations.
