Notes
- This counts questions asked in 2021 and questions closed in 2021 - the AskedAndClosed and PctAskedAndClosed columns reflect questions that were both asked and closed in 2021, while the remaining columns total up all questions closed in 2021 - even those asked in prior years.
- Reopen numbers also include questions asked in years prior - but limit themselves to questions that were closed in 2021 and then also reopened in 2021.
- If a question was closed twice, it'll be counted twice.
- If a question was reopened twice, it'll be counted twice.
