Languages popular among polyglot language learners

In April 2014, an admin of the Facebook Polyglots group created a poll on the languages that group members were studying. A few years later, I suggested to this admin another poll be conducted, but she shows no interest. This month marks the 10th anniversary. On April 15, I created the second poll. The results as of today (April 27) are shown below, along with those of the 2014 poll. (Mandarin is an entry separate from Chinese because it was so 10 years ago. Chinese was and is below the 10th place so it's omitted here.)

___2014____________2024
1 French 935 ------- French 39
2 Spanish 807 ------ Spanish 38
3 German 799 ------ German 28
4 English 651 ------- Italian 25
5 Italian 448 -------- English 17
6 Russian 428 ------ Portuguese = Mandarin 16
7 Portuguese 341
8 Japanese 312 ----- Russian = Japanese 14
9 Mandarin 308
10 Arabic 276 ------- Arabic 11

Obviously, this year's poll participation is very much lower, definitely because I don't have the charisma of the group admin, and probably also because more such groups have been created on Facebook, diluting the interest of language lovers in this particular group. (I do see much less traffic in this group over the years, in spite of membership growth.) But even with these small numbers, we can still draw some conclusions:

* French remains at the top, Spanish in the 2nd place, German the 3rd. But Spanish is very close to French now, while 10 years ago it was barely above German. (Is this related to the rapid growth of the Hispanic population hence the importance of Spanish?)

* Italian has taken over English, by a large margin.

* Russian dropped to below Portuguese. (Related to the current world affairs?)

* I had expected Mandarin to drop or remain as is. But it seems to have gained a little.

* Arabic firmly stays in the 10th place.
