Only 38% of Americans identify as having a secure attachment style, according to a YouGov poll of a nationally representative sample of U.S. adults. That figure sits well below the roughly 59% found in a landmark nationally representative study by researchers Kristin Mickelson, Ronald Kessler, and Phillip Shaver, published in the Journal of Personality and Social Psychology. Most people walk around assuming they handle closeness, conflict, and vulnerability the way a reasonably well-adjusted adult should. The research suggests a majority are managing something less settled than that, whether or not they’d describe it that way themselves.
What “Secure” Actually Means in a Relationship
Attachment style describes the patterns a person developed, largely in early relationships, for handling emotional closeness and distance. Someone with a secure style tends to trust a partner’s intentions by default, communicate needs directly, and stay relatively steady during conflict rather than either shutting down or escalating. The remaining, more insecure styles generally cluster into two broad tendencies: anxious patterns, marked by a heightened fear of abandonment and a need for frequent reassurance, and avoidant patterns, marked by discomfort with too much closeness and a pull toward independence even at the cost of intimacy. Most adults carry some blend of these tendencies rather than a pure type, but the dominant pattern still shapes how a relationship actually plays out day to day.
Why the Numbers May Be Shifting
The gap between the 1997 study’s roughly 59% secure figure and the newer poll’s 38% is large enough to be worth taking seriously, even accounting for differences in how the two surveys asked the question. Attachment researchers have pointed to a few plausible contributors: rising rates of family instability and divorce across the decades between the two surveys, increased awareness and willingness to name insecure patterns rather than default to “secure” out of unfamiliarity with the terminology, and broader cultural anxiety that shapes relationships from adolescence onward. It’s also possible that self-identification on a public opinion poll captures something different than a structured clinical assessment does, since people asked to label themselves may be more critical of their own patterns than a validated questionnaire would classify them.

The Everyday Cost of Not Knowing Your Pattern
What makes this more than an academic curiosity is how much attachment style predicts about ordinary relationship friction. An anxiously attached partner who reads a slow text response as rejection, and a securely attached partner who takes a slow response at face value, are having completely different emotional experiences of the exact same text message. Neither one is being irrational within their own framework. They’re simply running different internal models of what closeness and distance mean, often without either partner realizing that’s the actual disagreement underneath whatever fight they’re having about texting habits, plans, or how much space feels normal.
This is part of why so many recurring arguments in long-term relationships feel impossible to fully resolve. Couples often address the surface content of a fight, who forgot to call, who needs more alone time, without ever naming the deeper attachment pattern generating it. A partner’s need for reassurance or need for space isn’t usually a referendum on the relationship. It’s frequently a decades-old pattern showing up in a Tuesday-night conversation about weekend plans.
You Don’t Have to Stay Where You Started
The most useful finding buried in this research isn’t the percentage itself. It’s that attachment style, unlike a fixed trait, has been shown to shift over time, particularly through a stable relationship with a securely attached partner or through deliberate work in therapy. Being part of the roughly six in ten Americans who aren’t currently secure isn’t a permanent diagnosis. It’s a starting point, and one that’s a good deal more useful to name honestly than to assume away.
The most practical first step isn’t a formal assessment, though those exist and can help. It’s noticing the specific moments a relationship reliably triggers a strong reaction, a delayed text, a request for space, a partner wanting more closeness than feels comfortable, and asking honestly whether the reaction fits the moment or echoes something older. That single habit of noticing, done consistently over months rather than once in a heated argument, is often what actually moves someone toward the more secure end of the spectrum, regardless of which style they started with.
