What the Cigna Loneliness Figure Actually Measured

The number that keeps surfacing in policy discussion about remote work, hybrid offices, and young workers is 61%. Cigna’s 2020 workplace loneliness report put that share of U.S. adults as sometimes or always feeling lonely, a seven-point rise from the prior year, with 73% of workers aged 18 to 22 and over 80% of employed Gen Z reporting loneliness. It is a striking figure, and it has done real work in policy and corporate conversation: cited in arguments for return-to-office mandates, for employer wellness benefits, for treating remote and hybrid arrangements as a loneliness risk to be managed. Before that figure carries any more policy weight, it is worth asking exactly what it measured.

An index, not the UCLA scale

The academic literature on loneliness has largely converged on the UCLA Loneliness Scale, a 20-item instrument with decades of validation behind it. AARP’s 2018 survey of adults 45 and older used it directly, which is why its finding — one in three older U.S. adults report being lonely — sits comparably alongside other academic work using the same instrument.

Cigna’s figure comes from a different instrument: a company-branded loneliness index built for a workplace-focused survey, not the UCLA scale and not identical to it in item content or scoring. This is not a minor technical footnote. Two surveys asking “are you lonely” in different ways will produce different prevalence numbers even when sampling the same population at the same time, and there is no straightforward conversion between them. Cigna’s 61% and AARP’s one-in-three are not measuring the same thing with different results; they are, in a meaningful sense, measuring different things.

Harvard’s Making Caring Common survey, published a year later in February 2021, adds a third instrument and a third number: 36% of Americans reporting serious loneliness, with the figure jumping to 61% among adults aged 18 to 25. Note that this 61% belongs to a specific age band in a different survey using a different measure, not to Cigna’s all-adult finding. The coincidence of the digits is exactly the kind of thing that gets flattened in secondary reporting and policy citation, where “61%” travels without its denominator or its instrument attached.

What the workplace framing adds and removes

Cigna’s survey was fielded with workplace outcomes in mind: it reports that lonely workers miss work roughly twice as often for illness and five times as often for stress-related reasons. That framing is useful for an employer audience, but it also means the underlying loneliness measure was designed and contextualized around work, not around social life generally. A respondent answering a workplace-branded loneliness survey may be primed to think about colleagues and office relationships specifically, which is a narrower frame than the UCLA scale’s general items about feeling in tune with people around them or feeling part of a group of friends.

This matters for the technology and remote-work argument specifically. When the 61% figure is invoked to suggest that remote work drives loneliness, it is being asked to do causal work that a single cross-sectional survey, on a workplace-specific instrument, cannot do. The survey was fielded in a period, reported in January 2020, that predates the mass shift to remote work triggered by the pandemic; it cannot speak to whether remote arrangements adopted afterward increased or decreased loneliness relative to office work. Any policy argument that moves from “workers report loneliness” to “remote work causes loneliness” is supplying a causal claim the data were never positioned to test.

The generational number holds up better than the topline

The age pattern in Cigna’s data — elevated loneliness among the youngest workers — is corroborated elsewhere on different instruments, which gives it more standing than the topline 61%. The American Enterprise Institute’s 2021 survey on American friendship found 12% of Americans report having no close friends at all, up from 3% in 1990, with the decline concentrated among men. Harvard’s separate survey using its own measure also found youth loneliness elevated relative to older adults. Convergence across differently constructed instruments is a stronger form of evidence than any single number, and on the direction of the youth-loneliness finding, three separate surveys line up. On the exact magnitude, they do not, and should not be expected to.

What this means for policy citation

None of this means the Cigna figure is wrong or useless. It means it should be cited as what it is: a 2020 workplace-branded loneliness index finding, not a general-population UCLA-scale estimate, and not evidence about the causal effect of remote work. The UK’s 2018 loneliness strategy built its policy infrastructure on the Office for National Statistics adopting a standardized loneliness measure precisely to avoid the comparability problem this figure illustrates — a lesson worth applying to employer-sponsored survey instruments now circulating in policy debate.

A better basis for the remote-work-and-loneliness argument would be a longitudinal design following the same workers through a change in work arrangement, using a validated instrument such as the UCLA scale, with loneliness and structural isolation measured separately rather than folded into a single index score. Holt-Lunstad’s 2015 meta-analysis is a reminder of why the distinction matters: isolation and loneliness carried separate, independently significant mortality risk in that pooled analysis, which means collapsing them into one workplace index score obscures exactly the distinction a policy response would need to get right.
