Syllabus: Cambridge - International AS & A Level Business
Module: 3.1 The Nature of Marketing
Lesson: 3.1.6 Market Segmentation

Introduction

Market segmentation is a critical topic within the Cambridge International AS & A Level Business syllabus, specifically under section 3.1.6, “Market Segmentation.” This lesson falls under the broader theme of “The Nature of Marketing” and supports students in understanding how businesses target the right products to the right people. Segmentation also lays the groundwork for effective marketing strategies, resource allocation, and positioning—essential knowledge for students aiming to grasp how modern organisations create value in competitive markets.

This concept links directly to core commercial awareness competencies such as stakeholder analysis and market dynamics, and is particularly relevant for developing students’ workplace readiness and decision-making skills. It also supports Gatsby Benchmark 4 by linking curriculum learning to career contexts.

Key Concepts

Students should understand the following key points from the Cambridge specification:

• Definition: Market segmentation involves dividing a market into distinct groups of buyers with different needs, characteristics or behaviours.

• Bases for Segmentation: Includes demographic (age, gender), geographic (region, climate), psychographic (lifestyle, values), and behavioural (usage rate, brand loyalty).

• Benefits to Businesses: More targeted marketing, improved customer satisfaction, efficient use of resources, and competitive advantage.

• Challenges: Increased costs from tailored marketing strategies, risks of ignoring potential crossover customers, and complexity in managing multiple segments.

• Link to Targeting and Positioning: Segmentation is the first stage in the STP (Segmentation–Targeting–Positioning) model which underpins many strategic marketing decisions.

Real-World Relevance

Market segmentation is used every day by brands and organisations:

• Netflix tailors content and recommendations based on viewing behaviour and location, offering a personalised experience to different customer segments.

• Nike segments by sport, gender, lifestyle, and even self-identity—creating different marketing messages and products for runners, gym-goers, or fashion-conscious teens.

• Local councils segment services geographically and demographically, adjusting youth outreach programmes based on postcode, age group or employment data.

In the classroom, exploring how organisations shift their messaging across audience types (e.g., NHS campaigns for teens vs pensioners) makes segmentation tangible and relatable.

How It’s Assessed

In the Cambridge exam, this topic may appear in various forms across Paper 1 (short-answer and data response) and Paper 2 (structured essay-based questions):

• Command words to look out for include: define, explain, analyse, evaluate, and recommend.

• Short answer questions might ask students to identify segmentation types or benefits.

• Longer questions often explore segmentation’s role in marketing strategies and its impact on success or failure.

• Case study prompts may involve interpreting marketing data and advising on segmentation strategies for specific businesses.

Strong answers should:

• Use appropriate terminology (e.g. psychographic, niche marketing).

• Apply segmentation strategies to the context of the question.

• Evaluate trade-offs (e.g., increased targeting vs higher costs).

Enterprise Skills Integration

Market segmentation provides an ideal platform to build enterprise and career-readiness skills:

• Decision-Making: Students weigh up which segment(s) to target and how to position a product.

• Problem-Solving: When faced with declining sales, students explore whether better segmentation could increase relevance.

• Strategic Thinking: Understanding the commercial implications of serving one market versus multiple.

• Data Interpretation: Using market research and customer data to make informed recommendations.

These mirror real workplace challenges where marketing teams must segment markets using limited budgets and imperfect data, reflecting the kinds of commercial awareness employers value most.

Careers Links

Market segmentation connects directly to Gatsby Benchmarks 4, 5, and 6:

• Benchmark 4 – Students see how curriculum learning applies in real marketing, sales, public sector, and social enterprise careers.

• Benchmark 5 – Employer case studies and sector-specific marketing projects show how segmentation plays out across industries.

• Benchmark 6 – Simulated marketing campaigns can recreate workplace decisions, giving students a taste of career scenarios.

Relevant careers include:

• Marketing Executive

• Consumer Insight Analyst

• Advertising Account Planner

• Product Manager

• Communications Officer

Tools like Skills Hub Futures embed these links explicitly, enabling students to explore marketing roles while building commercial fluency.

Teaching Notes

Common Pitfalls:

• Students often confuse segmentation with targeting—use visual aids to reinforce the STP model as a process.

• Over-reliance on demographic examples—encourage students to explore psychographic and behavioural variables for deeper thinking.

Recommended Approaches:

• Case Study Comparison: Ask students to compare how two brands (e.g. Lidl vs Waitrose) segment and target different consumer groups.

• Live Data Activity: Use anonymised Google Trends or YouGov profiles to explore real-world segment data.

• Role Play Exercise: Assign teams different customer segments and challenge them to pitch the same product with tailored messaging.

Extension Opportunities:

• Integrate with Maths to explore how segmentation informs profit margins or pricing.

• Link to Geography through spatial segmentation (e.g., flood zone products).

• Use Enterprise Skills simulations for applied decision-making under real-world constraints.
