Five ways researchers must rethink insight design for the new Singleton Economy

For decades, insight frameworks have quietly assumed that the heads of the household is plural. Two adults. Shared budgets. Negotiated decisions. Even when research questioned “individual preferences,” those preferences were typically shaped by compromise.

In reality, this assumption is becoming more and more outdated across developed markets, with single‑person households firmly on the rise. In North America, 41% of women aged 25–35 are single, a share that has doubled over the past 50 years, and Morgan Stanley forecasts that 45% of women aged 25–44 will be childless and single by 2030. This is not a marginal life stage, it is a durable consumer configuration with profound implications for how demand is formed, expressed and sustained.

Here are five ways researchers must adapt to the rise of the singleton economy.

1. Reframe segmentation around autonomy, not household structure

Traditional segmentation models still over‑index on marital status, “family lifecycle,” or household size. Yet these variables increasingly obscure rather than explain behaviour.

The more powerful lens is autonomy: who holds decision authority, who carries responsibility, and who absorbs cognitive load. The sovereign singleton makes purchases without negotiation, justification or deferral. There is no “regression to the mean” or compromise on products, e.g. buying the mild over spicy option to keep the peace.

This produces sharper preferences, lower tolerance for friction, and faster rejection of generic solutions. For researchers, this means moving beyond static household categories toward segmentation based on decision sovereignty, perceived responsibility, and tolerance for compromise.

2. Track the rise of self‑gifting, self‑investment and sovereignty‑based drivers

Single consumers are often framed as indulgent or discretionary spenders. The evidence suggests the opposite.

McKinsey finds that U.S. consumers now allocate nearly 90% of their free time to solo activities, including shopping, fitness, and social media. At the same time, the global self‑improvement market is growing at roughly 8% per year, expanding from $46.1B in 2025 to a projected $90.9B by 2034, nearly doubling in under a decade. Together, these signals point to a sustained shift toward inward, self‑directed forms of consumption.

For the sovereign singleton, spending skews away from episodic “treats” and toward self‑gifting as self‑investment—focused on maintenance, optimisation, resilience, and proof of progress. These purchases function less as reward and more as personal governance. To capture this shift, research frameworks must distinguish indulgence from autonomy‑driven investment, and measure intent, continuity, and future‑orientation, rather than occasion alone.

3. Read new rituals as cultural signposts, not side‑trends

As romantic partnership becomes optional rather than assumed, social and emotional needs are being redistributed. This has given rise to new rituals like Galentine’s, Friendsgiving, Friendmas that operate as identity markers rather than calendar novelties.

Searches for “Galentine’s Day” have surged, with reports indicating a rise of over 1,600% over the past five years, while nearly 45% of Gen Z report planning to celebrate Friendsmas, compared with just 13% of over‑65s. These rituals signal a shift toward decentralised intimacy, where connection is spread across friendships and communities rather than concentrated in a partner.

For researchers, these rituals are not fluff. They act as leading indicators of how people organise belonging, allocate budgets, and legitimise non‑traditional milestones. Tracking them provides insight into where emotional and cultural value is migrating.

4. Recognise that single women are leading economically, not lagging

One of the most persistent myths in insight work is that single women are economically precarious. The data tells a different story.

Pew Research shows that among unmarried adults, single women without children hold higher median wealth ($87,200) than single men ($82,100). In housing, single women consistently outpace single men as buyers, accounting for more than one‑fifth of home purchases in some markets, despite earning less on average.

These are high‑stakes, long‑horizon decisions made without shared risk or financial backup. For researchers, this challenges outdated assumptions about risk aversion, confidence and purchasing power. Models that treat single women as cautious or transitional miss the reality of deliberate, sovereign economic behaviour.

5. Adapt methods to capture micro‑motivations and non‑linear journeys

Finally, the singleton economy exposes weaknesses in linear decision models. Without shared timelines or social pressure to “hit milestones,” buying journeys become more fluid, recursive and self‑paced.

Micro‑motivations matter more: relief, reassurance, control, personal fit. Decision journeys loop, pause, accelerate and abandon faster. Stated preference methods that rely on averaging or hypothetical trade‑offs increasingly fail to capture this complexity.

Researchers need more temporal methods like diaries, ethnography, in‑the‑moment tracking and fewer assumptions about orderly funnels. When one person carries 100% of decision weight, motivations surface quickly and disappear just as fast.

The insight opportunity here

The singleton economy doesn’t just redefine consumption; it redefines how insight must be gathered and interpreted. In a market built for two, the fastest growth now comes from understanding the one.

For researchers willing to reframe segmentation, follow new rituals, interrogate motivation at a micro level and take single consumers—especially women—seriously as economic actors, the reward is sharper insight and fewer blind spots.

Because sovereignty changes everything.
