Data visualization cares disproportionately far too much about designing for colorblindness relative to other disabilities that are more common (visual impairments included).

(A thread on disability, race, and patriarchy in data visualization.)

~4.5% of people with northern European ancestry are colorblind. But less than half of a percent of women are.

This means that nearly 8% of men from a northern European background have some form of colorblindness.

*Colorblindness affects WHITE MEN the most.*

Why does this matter?

Because designers, scientists, and engineers in our field continue to produce palettes, guides, research, and tools for dealing with colorblindness when visualizing data.

But where are tools and resources for all the other kinds of disabilities out there?!

Why do we have far more resources for dealing with colorblindness (<4% global rate) than low vision, which affects just over 30% of people?

I'd reckon it all started in academia...

Academic discourse on scientific visualization and color perception (alongside computer science) is decades old.

I'm sure there is a paper waiting to be written about the demographics of peer reviewers, but I can guess they were mostly white men.

Ask: WHO was this science for?

While the origins of the imbalance here might be conjecture (because who has asked these questions yet?), it should not be a surprise that we have more resources on accessibility for a very specific disability of white men than virtually every other major disability.

So now what??

My solution is simple:
Prioritize more discourse, research, guides, palettes, and tools that help with other functional disabilities and disabled communities.

And please stop writing about colorblindness in visualization. We have enough of those blogs already!

Resources we could use more of (1/?):
Low vision (~30% of all people):
- High contrast text
- High contrast elements
- Using texture, shape, units
- Designing with zoom/magnification
- Using Hierarchy and Focus
- Using annotations or guides

Resources we could use more of (2/?):
Functional/motor impairment (~13% of all people in US):
- Keyboard interactivity/navigation
- UI alternatives to in-chart controls (brushing, subselecting, etc)
- Alternative data navigation schemes
- Scrollytelling alternates

Resources we could use more of (3/?):
Cognitive disability (~11% of all people in US):
- Captions, summaries, clear titles, and plain text alternatives
- Reducing visual complexity
- Forgivable user interactions
- Use of hierarchy
- Assistive design (how-to-read guides, help)

Resources we could use more of (4/?):
Attention deficit/hyperactive disorder (~9% of all people in US):
- Clear, short text summaries
- Object constancy
- Motion design and animation
- Use of breadcrumbs
- Interaction history (with undo/redo functions)

Anyway, the list goes on. These are just a few!

Black, disabled people in the south are ESPECIALLY (disproportionately) excluded from the design of equitable data systems! Include them!

If data is really so important, why is it only accessible for a select few?

It is time for data visualization to grow up.

Okay this is getting a little traction already! So come to my talk on Accessibility and Data Visualization with @LareneLg and @liatrisbian at @OutlierConf! https://twitter.com/OutlierConf/status/1349385938632380416?s=20
