Glass Ceiling Index

Glass Ceiling Index is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Glass Ceiling Index rather than just read about it. In short: Glass-Ceiling Index (GCI) is an annual index used to help visualize the glass ceiling metaphor by ranking OECD countries on their extant performance on gender equality. Created by The Economist in 2013, it assesses data on a variety of indicia related to gender in areas including higher education, labour-force participation, pay, childcare costs, maternity and paternity rights, business-school applications, and repr…

Key takeaways

Glass Ceiling Index belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Glass Ceiling Index to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Glass Ceiling Index from memory before moving on to harder problems.

Reference excerpt

Glass-Ceiling Index (GCI) is an annual index used to help visualize the glass ceiling metaphor by ranking OECD countries on their extant performance on gender equality. Created by The Economist in 2013, it assesses data on a variety of indicia related to gender in areas including higher education, labour-force participation, pay, childcare costs, maternity and paternity rights, business-school applications, and representation of women in senior government roles. In the 2024 index, the countries where inequality was the lowest were Iceland, Sweden, Norway, Finland, and France. The countries lowest on the index were Israel, Switzerland, Japan, Turkey and South Korea. The index points to where and how women are still lagging their male counterparts in senior business roles. It is updated every year in a rank of 29 OECD countries. It was launched in 2013 when there were five indicators and 26 countries, but today consists of ten indicators (higher education, labour-force participation, gender wage gap, GMAT exams taken by women, women in managerial positions, women on company boards, net child-care costs, paid leave for mothers, paid leave for fathers and women in parliament) for 29 OECD countries.

Worked examples

Example 1 — a first encounter with Glass Ceiling Index

Start with the simplest possible case. Write down what Glass Ceiling Index claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Glass Ceiling Index before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Glass Ceiling Index ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Glass Ceiling Index

In research: Glass Ceiling Index appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Glass Ceiling Index in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Glass Ceiling Index is common in secondary-school and first-year university syllabi. It links to neighbouring topics Employment discrimination, Feminist economics, Feminist terminology, so understanding it makes those chapters shorter.
In everyday life: Look for Glass Ceiling Index outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
