Market Segmentation and Market Mapping
What Is Market Segmentation?
Market segmentation is the process of splitting a broad customer base into smaller, more homogeneous groups. Rather than trying to sell to everyone in exactly the same way, a business identifies which groups of customers share similar needs and tailors its product, price, promotion and distribution to fit those groups specifically. This makes marketing more efficient — the right message reaches the right people at the right time.
Without segmentation, a business risks wasting money on marketing that reaches people with no interest in the product, or producing a product that tries to please everyone and ends up satisfying no one. A clear understanding of segments allows a business to focus its limited resources where they will have the most impact.
Markets can be segmented by location (where customers live), demographics (age, gender, occupation), lifestyle (values, interests, hobbies), income (how much customers earn and what they are willing to spend), and age (the age group the product is aimed at). Each method reveals a different way of grouping customers.
Ways of Segmenting a Market
Location — businesses may target customers in specific towns, regions or countries. A local market stall in Bristol targets customers within a short travel radius. An e-commerce business might segment by country to account for different language preferences, currencies or delivery costs.
Demographics — age, gender, occupation and family size are the most common demographic variables. A children’s toy brand targets parents of young children; a luxury car brand targets high-income professionals. Demographic data is widely available from government statistics and commercial providers, making this one of the most cost-effective segmentation approaches.
Lifestyle — lifestyle segmentation groups customers by what they value and how they live, rather than purely by age or income. Two people of the same age and income might have very different lifestyles: one prioritises sustainability and ethical consumption, another prioritises status and luxury. Brands like Patagonia (outdoor, sustainability-focused) and Rolex (prestige, achievement) sell to different lifestyle segments even if their customers overlap demographically.
Income — segmenting by income helps a business set prices that match what customers can afford. Budget supermarkets such as Aldi target price-sensitive shoppers; premium chains target higher-income households prepared to pay more for quality and experience. Many businesses offer multiple tiers — a budget range, a mid-range and a premium range — to capture several income segments simultaneously.
Age is one of the most-used segmentation variables in UK business. The UK’s ageing population has created rapidly growing markets in retirement living, mobility products, financial planning for over-55s, and leisure activities suited to older adults. Conversely, Gen Z consumers (born roughly 1997–2012) are the primary target for many social-commerce brands, subscription apps and sustainability-focused products. Businesses that identify which age group their product is most suited to can allocate their marketing budget far more precisely than those treating all adults as a single market.
Market Mapping
Market mapping (also called perceptual mapping) is a visual tool that plots brands or products on a grid using two variables, typically price (low to high) and quality (low to high). By seeing where existing competitors sit, a business can spot a gap in the market — a position on the map that is not currently occupied by a rival.
Consider a local coffee market. If a market map plotted all existing cafés by price (vertical axis) and quality (horizontal axis), and most clustered in the “low price / low quality” and “high price / high quality” corners, there might be a gap in the “medium price / high quality” position. An entrepreneur could position a new café there to fill the gap and avoid direct competition with established players.
Market maps are only as reliable as the data used to build them. If the entrepreneur has not conducted thorough research, the map may misplace competitors or overestimate a gap. A gap on a map does not automatically mean demand exists — there may be a reason no business occupies that position (e.g. the combination is unviable: extremely high quality at very low price requires a cost structure most businesses cannot sustain). A market map is a starting point for investigation, not a guarantee of success. It should always be used alongside primary research to confirm that customers actually want the product a gap suggests.
A market map uses two axes (e.g. price and quality) to plot competitors and identify an unoccupied position — a gap in the market. The gap represents a potential opportunity, but a business must verify through primary research that genuine customer demand exists before entering.
