@MumoftwoNC I am pondering this and would agree the illustration is perhaps a bit crude (hence posting discussion of it in the link above), but I don't have the brain power tonight to properly explain. The colour of the people is perhaps a distraction.
Tall = advantage/no barriers
Small = disadvantage/barriers
I wouldn't usually do this and am really not keen on the AI summary sythesis paragraphs, but I have checked it and it seems pretty accurate:
"The image most often used to explain equity versus equality shows three people of different heights trying to see over a fence. In the equality illustration, each person receives a box of the same size, but only the tallest person can see over the fence. In the equity illustration, people receive boxes of different heights tailored to their needs, allowing everyone to see over the fence and enjoy the view.
Equality
Concept: Treats everyone identically, providing the same resources or opportunities.
Visual: Three people, each receiving a single, identical box to stand on.
Outcome: Only the tallest person can see over the fence, while the others still cannot.
Equity
Concept: Acknowledges individual differences and provides resources based on need to ensure everyone has a fair chance to succeed.
Visual: The same three people, but they each receive a differently sized box. The shortest person gets the tallest box, the middle person gets a medium-sized box, and the tallest person may not need one at all.
Outcome: All three people are able to see over the fence.
Why the difference matters
Fairness:
While equality treats everyone the same, equity focuses on fairness by ensuring everyone gets what they need to reach the same outcome.
Addressing barriers:
Equity addresses the specific barriers different individuals face, creating a truly inclusive and supportive environment.
Driving change:
Equity is about driving deeper, more meaningful change by tackling the root causes of disparity, rather than just providing the same surface-level treatment."
I think this stand in UK and US, though as PP have expressed the execution/application of EDI/DEI in practice does have differences in each country.
