Data was taken from @DdmrDdmr Merit Dashboard. I suggest checking that if you want more in depth overview of the each board.
Number of posts between June 1st and June 30th
One thing is immediately obvious, when compared to previous month- Russian board is not on the top, and not even on the list, due huge amount of posts deleted for some reason (more than 12,000) therefore getting into negative difference. With the absence of Russian board, German is on the top, followed by Turkish. Most of the boards that were in the top half last month had less had less activity, like French, Italian, Spanish and few others. Some like Arabic had quite a few deleted posts as well, making them look less active than they actually were.
Number of merit between June 1st and June 30th
No big changes at the top, Russian board is there as always, and German at the 2nd. Turkish board experienced heavy drop in the terms of shared merit, but something like that was expected because they lost one big merit source who was generating huge percentage of their merit. Two other big boards also had big merit drop for some reason; Spanish went down from 429 to 175 and Italian from 903 to 507.
Merit senders and receivers per local board between June1st and June30th
Previous month was the first time I introduced this chart, and I decided to keep it as I think that it is a decent indicator of the amount of active members on the each board. If you are active on your local board, chances are good that you will either send or receive at least 1 merit in one month period.
Merit/Post ratio between June1st and June30th
After few months absence due negative post difference, Arabic board is back on this chart. Again they had huge amount of posts deleted, that lead to this unrealistically high merit/post ratio. As expected, Turkish board went down a lot on this list compared to last month. Bottom of the chart is reserved for Croatian local board, like in previous months.
