Customer segmentation, and the one-person customer most brands miss

Three in ten Canadian homes are a party of one. Per head, people who live alone outspend everyone else, and most of them say products aren't built for people like them. That gap is what good customer segmentation is supposed to find.

The short version

Customer segmentation means splitting your customers into groups that share something which changes what they buy, how they buy or what they need from you. You then build the offer, the price and the message for each group instead of for one imaginary average customer.

The payoff is easiest to see in a segment most brands still overlook. One-person households are now the most common household type in Canada, at 29.3% of all homes in the 2021 Census.¹ Boston Consulting Group's August 2026 consumer research found that across mature markets these households spend two to three times more per capita than multi-person households, yet 50% to 70% of people living alone said products and services aren't built for people like them.³ A large, valuable group that feels ignored is exactly what segmentation exists to surface.

The segment hiding in plain sight

Living alone went from unusual to typical in a single generation. In 2021, 4.4 million Canadians lived alone, up from 1.7 million in 1981, and in 2016 one-person households became the most common household type for the first time in the country's history.² They now edge out couples without children (25.6%) and couples with children (25.3%).¹

Walk through most marketing and you'd never guess it. Family packs, couples' packages, "bring a friend" offers, ads full of kitchens with four chairs at the table. None of that is wrong, but it speaks to a shrinking share of homes, and it tells a big group of buyers the product was designed with somebody else in mind.

Read the per-capita number carefully

"Two to three times more per capita" is the kind of statistic that gets misquoted, so it is worth being precise. It means spending per person, not per household. A couple shares one rent, one set of utility bills and one fridge; a person living alone pays for all of it. Part of that higher spend is structural. It doesn't mean solo households are splurging on everything.

What it does mean is that each solo customer carries more of the cost of running a home, and they notice when a product forces them to overbuy or overpay. That is where the opportunity sits: pack sizes that fit one person, pricing that doesn't penalise a single booking, services that work around one person's schedule. Brands that get those details right earn loyalty from a group that is used to being an afterthought.

Solo does not mean young and single

This is where lazy segmentation goes wrong. Picture "people who live alone" and most marketers see a 28-year-old in a downtown condo. The data says otherwise. In 2021, 42% of Canadians aged 85 and older lived alone, compared with 7% of people aged 20 to 24, and Statistics Canada attributes the rise in solo living almost entirely to an aging population.²

So "solo household" covers several segments: young renters, people living alone after a separation, and older adults who have lost a partner. They share a household size and almost nothing else. The lesson carries beyond this example. A single variable rarely makes a useful segment; you usually need to layer two or three.

The four types of customer segmentation

Most segmentation work combines four lenses. Here is what each one groups customers by, with the solo household running through as the example:

Demographic segmentation is where most businesses start because the data is easy to get: age, household size, income, life stage. It tells you who is buying, but on its own it rarely tells you why. Geographic segmentation matters most for local businesses, since a neighbourhood's housing stock shapes who lives there. Psychographic segmentation looks at values and priorities, and it is often what separates two customers who look identical on paper. Behavioural segmentation groups people by what they do: how often they buy, through which channel, and how price-sensitive they are. For B2B firms, firmographic segmentation (company size, industry, revenue) plays the role demographics play in consumer markets.

Customer segmentation examples for service businesses

Here is how the solo-household lens changes the work in industries we know well.

Realtors

A buyer purchasing alone qualifies on one income, which changes the price range, the property type and the questions they bring. One-bedroom condos, townhouses and smaller detached homes become the core inventory, and content about buying on a single income answers a question family-focused marketing never asks. Our guide to real estate lead generation covers how to reach these buyers once you know who they are.

Beauty, wellness and med spas

Solo clients book for themselves, often at the edges of the day, and they value easy online booking and no pressure to bring a friend. Couples' packages and "bring a friend" promos do little for them; a loyalty perk for regular solo visits does more. See our med spa marketing guide for the channel side.

HVAC and home services

For someone who lives alone, and especially an older customer, letting a stranger into the house carries more weight. Named technicians with photos, a text before arrival, firm appointment windows and clear pricing all build the trust that wins the job. Those details belong in your ads and on your booking page, not only in the van. Our HVAC marketing work builds them in.

Insurance and financial services

Solo renters need tenant insurance, solo owners weigh life and disability cover differently when nobody else depends on their income, and older customers living alone think about who can act for them. Segmenting by household type turns one generic pitch into three relevant ones.

How to segment your own customers in five steps

1. Start with the data you already have

Invoices, your CRM, booking notes and past emails hold more than you think. Pull a year of customers and note what you can: location, what they bought, how often, how they found you, and anything they told you about their household.

2. Pick the variables that change behaviour

A variable is only useful if it changes what the customer needs. Household size might matter for a caterer and mean nothing for a tax accountant. Choose two or three that plausibly change the purchase.

3. Size and value each segment

For each group, estimate how many customers you have, their revenue, their margin and how much they cost to serve. A small segment with high margins and low churn can be worth more than a large one that only buys on discount.

4. Talk to real customers

Five to ten short conversations per segment will tell you more than a spreadsheet. Ask what almost stopped them buying and what they wish you offered. When a solo customer says your packages feel designed for couples, you have found something worth fixing.

5. Build one offer and one message per priority segment, then test

You don't need a new brand for each group. You need a landing page, an ad set or an email that speaks to their situation. Run it against your generic version and watch cost per lead and conversion. Our guide to measuring marketing ROI shows how to keep score.

From segmentation to positioning

Segmentation is the first step of what marketers call STP: segmentation, targeting, positioning. Once you know your segments, you choose which ones to serve (targeting) and decide how you want those people to see you compared with the alternatives (positioning). Our brand positioning guide picks up from here, and a positioning statement puts the choice into one sentence. To see where you sit against competitors for a given segment, plot it on a positioning map, then trace each segment's path to purchase with a customer journey map.

Mistakes that make segmentation useless

• Too many segments. If you can't build a distinct offer for a segment, it isn't worth tracking. Three to five is plenty for most small businesses.
• Segments you can't reach. A segment only helps if you can find those people through a channel you can afford.
• Stereotypes in the creative. Showing every solo customer as a young professional alienates the older half of the group. Check the imagery against the data.
• Segmenting once and forgetting. Household patterns shift with each census. Revisit your segments every year.

Frequently Asked Questions

What is customer segmentation?

Customer segmentation is splitting your customers into groups that share traits which change what they buy, how they buy or what they need from you. You then shape the offer, price and message for each group instead of marketing to one average customer.

What are the four types of market segmentation?

Demographic (age, household size, income, life stage), geographic (country, city, neighbourhood, climate), psychographic (values, priorities, lifestyle) and behavioural (purchase frequency, channel, loyalty, price sensitivity). Most useful segments combine two or three of these. B2B companies add firmographic segmentation, such as company size and industry.

What is an example of demographic segmentation?

Segmenting by household size is a strong one. One-person households are the most common household type in Canada, at 29.3% of homes in the 2021 Census, and BCG found people living alone in mature markets spend two to three times more per capita than multi-person households. A brand that sizes its packs, pricing and services for one person is using demographic segmentation.

Do people who live alone spend more?

Per person, yes. BCG's August 2026 research found solo households in mature markets spend two to three times more per capita than multi-person households. That is spending per person, not per household, and part of it is structural: one person pays the whole rent, the utilities and the running costs a couple would share.

What is the difference between segmentation, targeting and positioning?

Segmentation divides your market into groups. Targeting is choosing which of those groups to serve. Positioning is deciding how you want the chosen group to see you compared with the alternatives. Together they are known as STP, the core sequence behind most marketing strategy.

How many customer segments should a small business have?

Usually three to five. Each segment should be large enough to matter, different enough to need its own offer or message, and reachable through a channel you can afford. If you can't build something distinct for a segment, merge it with another.

How do you find an underserved customer segment?

Look for groups that are large or growing but poorly served by current offers. Check census and industry data for shifts, then talk to customers and ask what nearly stopped them buying. When people say a product wasn't designed for someone like them, as 50% to 70% of people living alone told BCG, you have found a gap.
