Thanks Brittany! Actually your approach is more impressive... I thought it would be easier (& efficient). So most days, I just duplicated the dashboard, swapped the chart & revised the title/description.

Thanks Brittany! Such a great little technique & I really love how compact the bar chart is.
I thought the vertical labeling was a nice touch... it might be handy or helpful especially if someone starts adding a 3rd or even a 4th bar to the mix... π

No idea.π
It could be a function of greater awareness, improved diagnosis, population growth, changes in school inclusion policies, etc.
Interestingly, if you look at all special education enrollment, about 50% remain unidentified for a specific exceptionality... so the # might be higher

Thanks Kit! I generally use Tableau to do my data visualizations...
You're right... The survey asks about their level (scale of 0-10) of meaning or purpose in life. But in my mind, there might be some overlap, so I was just using it as a proxy for "boredom." I also considered using "loneliness"...
