Equity Versus Equality
Definition
Equity: fairness in how income and opportunity are shared, which may mean treating people differently according to their need.
Equality: sameness, where everyone receives the same regardless of their circumstances.
Two Different Ideas
- Because fairness turns on need, effort and circumstance, equity can justify giving people unequal amounts.
- Equality insists on identical shares, so it ignores those differences and can leave a genuine need unmet.
- Horizontal equity means treating people in the same situation in the same way.
- Vertical equity means treating people in different situations differently, such as taxing higher earners more.
Why They Differ
- An equal split is not always fair, and a fair split is not always equal.
- Because fairness depends on need and effort, equity often requires an unequal distribution.
Example
- A charity has £1,000 to share among 10 people.
- An equal approach divides the fund evenly per person, even though one person has no income and another earns £900:
- That is £100 each, so equal shares leave the gap between rich and poor almost unchanged.
- An equitable approach gives £300 to the poorest and little to the richest, targeting need.
- So equity aims at fairness while equality aims at sameness.
Policy Link
- Progressive taxes and targeted benefits pursue vertical equity rather than strict equality.
- Yet pushing redistribution further can blunt work and investment incentives, so there is an equity–efficiency trade-off, and how far to go depends on the value society places on fairness against efficiency.
- Judging whether a distribution is fair rests on value judgements, so it is a normative question.
Exam technique
- Define both terms separately before comparing them.
- Use horizontal and vertical equity to add precision to a fairness answer.
- Flag that fairness is normative and depends on value judgements.
Common Mistake
- Do not use equity and equality as if they mean the same thing.
- Equity is about fairness, not about identical shares for everyone.
- A more equal outcome is not automatically a fairer one.
Self review
- Define equity and equality.
- What is the difference between horizontal and vertical equity?
- Why might a fair distribution be unequal?
- Why is judging whether a distribution is fair a normative question?
