4.2.3 Market Segmentation

Understanding the diverse needs and preferences of potential customers is crucial for businesses. Market segmentation offers businesses the chance to categorise their target audience into smaller, more specific groups, enabling tailored marketing approaches. This segmentation is particularly crucial in addressing the challenges in international marketing, where cultural and regional differences significantly impact consumer behaviour.

What is Market Segmentation?

Market segmentation is the process of dividing a broad market into distinct subsets of consumers with similar needs and characteristics. By doing so, businesses can tailor their offerings and marketing strategies to meet the specific needs of each segment more effectively.

Criteria for Segmenting Markets

Market segmentation can be based on a variety of factors. It's essential to select the criteria that are most relevant to the product or service being offered. When developing products, marketers must decide whether to adopt global or local marketing strategies, which can depend heavily on the geographic segmentation insights.

1. Demographic Segmentation

  • Age: Different age groups have different needs and preferences.
  • Gender: Certain products may appeal differently to males and females.
  • Income Level: Income can determine purchasing power.
  • Occupation: Professionals may have different needs compared to non-professionals.
  • Education: The level of education can influence purchasing habits.
  • Family Size: Products suited for larger families differ from those for smaller families.

2. Geographic Segmentation

  • Country/Region: Cultural and regional differences can influence product preferences.
  • Urban vs. Rural: Urban consumers may have different needs than those in rural areas.
  • Climate: Products suited for cold climates may not be as relevant in warmer areas.

3. Psychographic Segmentation

  • Lifestyle: Different lifestyles dictate different product needs.
  • Social Class: People from different social classes might have varying preferences.
  • Personality Traits: Certain products might appeal to specific personality types.

4. Behavioural Segmentation

  • Purchasing Habits: How often and when a customer buys a product.
  • Loyalty: Some consumers are brand loyal, while others are more flexible.
  • Usage Rate: Regular users versus occasional users.
  • Benefits Sought: The specific advantage a customer is looking for in a product. It's also crucial to align this with product strategies to ensure the right features are highlighted.

Methods for Segmenting Markets

Once the criteria for segmentation have been chosen, businesses must then decide how they will segment the market.

1. Single-variable Segmentation

This method focuses on segmenting the market based on one variable at a time, such as age or geographic location. It's a straightforward approach, particularly useful when a product primarily appeals to a specific group.

2. Multi-variable Segmentation

Using multiple criteria can offer a more nuanced view of potential customers. For instance, segmenting based on both age and lifestyle can provide insights into the preferences of younger consumers who lead active lifestyles.

3. Cluster Analysis

This statistical method groups consumers based on multiple variables, ensuring that members of a segment are as similar to each other as possible and as different as possible from members of other segments.

4. Perceptual Mapping

A visual tool, perceptual maps plot consumer perceptions of specific brands or products. This method helps businesses understand how consumers perceive their product in relation to competitors and can complement marketing mix decisions.

Why Segment Markets?

Effective market segmentation has several benefits:

  • Tailored Marketing: Allows for more personalised marketing strategies.
  • Effective Resource Allocation: Businesses can allocate resources more efficiently by focusing on the most profitable segments.
  • Better Product Development: Understanding specific segment needs can guide product improvements or the development of new products.
  • Competitive Advantage: Targeting underserved segments can give businesses an edge over competitors. Segmenting effectively also enhances promotion strategies, allowing businesses to reach out more effectively to their chosen demographics.

In the world of marketing, understanding and catering to specific market segments is key. By tailoring products and marketing efforts to specific groups, businesses can more effectively reach and resonate with potential customers.


Geographic segmentation divides the market based on location, such as regions, countries, or cities. Businesses might opt for it because consumer preferences often vary by location due to factors like climate, culture, and local traditions. For instance, a clothing brand might promote heavier garments in colder regions and lighter ones in warmer areas. However, relying solely on geographic segmentation can be limiting as it doesn't consider other significant factors, such as age or behavioural patterns. A diverse city, for instance, might have multiple target segments with varied preferences within the same geographic area.

Technological advancements, particularly in data analytics and digital marketing, have revolutionised market segmentation. Advanced algorithms can now analyse vast amounts of data to identify subtle patterns and emerging market segments, offering highly personalised marketing opportunities. Additionally, online platforms enable businesses to target ads based on specific segmentation criteria, like browsing history or online behaviour. While technology offers precision and scalability, businesses should also ensure they respect data privacy regulations and ethical considerations when segmenting and targeting consumers.

Market segment size refers to the number of potential customers within a specific market segment. It's crucial because it helps businesses assess the potential profitability of targeting that segment. A large segment may offer significant revenue potential, but it might also come with intense competition. Conversely, a smaller segment might provide a niche market with loyal customers, though with limited growth potential. Businesses must analyse segment size alongside other factors like competition, potential growth, and alignment with business objectives before deciding on target segments.

Psychographic segmentation categorises consumers based on their lifestyles, values, personalities, and interests. It goes beyond the surface-level information offered by methods like demographic or geographic segmentation, giving marketers a deeper understanding of consumers' motivations, preferences, and lifestyles. By integrating psychographic data with other segmentation methods, businesses can develop more personalised and effective marketing campaigns. For example, a sports apparel brand might use psychographic data to identify environmentally-conscious consumers and subsequently promote a new line of sustainable clothing to this specific segment.

Behavioural segmentation divides consumers based on their behaviour towards products, including purchase history, brand loyalty, or product usage rate. It offers insights into why consumers decide to buy or not buy a product. In contrast, demographic segmentation categorises consumers based on observable characteristics like age, gender, or income. While demographic data can suggest potential buying behaviours, behavioural segmentation provides direct evidence of what consumers do, allowing for more tailored marketing campaigns. For instance, offering special discounts to loyal customers can be an effective strategy derived from behavioural segmentation.

Practice Questions

Explain the difference between single-variable and multi-variable segmentation, and highlight a situation where each method would be most appropriate.

Single-variable segmentation divides the market based on one criterion at a time, such as age or geographic location. It offers a straightforward approach, especially when a product or service predominantly appeals to a specific group. For instance, children's toys might primarily target a certain age group. On the other hand, multi-variable segmentation considers multiple criteria simultaneously, offering a more nuanced understanding of potential customers. An example could be a luxury sports car brand targeting younger individuals with a high-income level. By using both age and income, the brand can tailor its marketing more precisely.

Describe the significance of perceptual mapping in market segmentation and how businesses can benefit from it.

Perceptual mapping is a visual tool used in market segmentation that plots consumer perceptions of specific brands or products relative to others. It provides insights into how consumers view a brand or product compared to its competitors, revealing potential market gaps or areas of saturation. For businesses, perceptual mapping helps identify positioning opportunities, allowing them to differentiate their offerings from competitors. For instance, if a company identifies that consumers perceive their product as high quality but expensive, they might decide to launch a more affordable range to cater to a broader segment, ensuring they don't neglect potential customers who are price-sensitive.
