🎯 What is market segmentation?

Big Idea: Market segmentation means dividing a market into groups of customers who share similar characteristics. Instead of treating everyone the same, you target specific groups with tailored products and marketing! 🧩

What is a market segment?

A market segment is a group of customers within a larger market who share similar needs, wants or characteristics.

If asked to 'define market segment', say: a group of consumers within a market who share one or more common characteristics that influence their purchasing behaviour.

📊 Ways to segment a market

Businesses can divide customers into segments using different criteria.

  • Demographic — age, gender, family size, income level, education
  • Geographic — country, region, urban vs rural, climate
  • Psychographic — lifestyle, values, personality, interests
  • Behavioural — buying habits, brand loyalty, usage rate, occasion
Example: A sportswear company might segment by age (teens vs adults), income (budget vs premium), and activity (running vs yoga).
Remember the 4 segmentation bases: 'Did George Play Basketball?' — Demographic, Geographic, Psychographic, Behavioural! 🏀
