Introduction
Adults, and young men in particular, are reporting less partnered sex than any cohort measured in the modern survey era. The phenomenon now circulates under the label "the sex recession," a term that has migrated from a magazine cover into peer-reviewed sociology, published journals, and discussions about male wellbeing.
The decline is most pronounced among males under thirty-five, intersecting with concerns about loneliness, delayed partnering, labor-force detachment, and mental health. But there are different effects among other age groups in this phenomenon.
This article examines what the sex recession is, how the numbers have moved, why researchers think it is happening, and what it means for the men living through it.
What the Sex Recession Refers To
The sex recession describes a sustained, multi-decade decline in the frequency of partnered sexual activity among adults in industrialized countries, with the sharpest drop concentrated among young adults.
The decline shows up in two related but distinct measures: a fall in how often sexually active people have sex, and a rise in the share of adults who report no partnered sex at all over the prior year.
Comparable patterns have been reported in the United States, the United Kingdom, Germany, Australia, Japan, and France, suggesting that whatever is driving the trend is not specific to a single national culture.
Origins of the Research
The body of work most often credited comes from Jean M. Twenge, a professor of psychology at San Diego State University, whose research on generational change drew attention with millennials and the Gen Z cohort.
In 2017, Twenge and her co-authors Ryne Sherman and Brooke Wells published two influential papers in the Archives of Sexual Behavior: one documenting declines in sexual frequency among American adults between 1989 and 2014, and a second showing that Americans born in the 1980s and 1990s were significantly more likely to report having had no sexual partners as adults compared to the Generation X cohort at the same age.
Twenge has since described early-twenties adults as roughly two and a half times more likely to abstain from sex than their Gen X counterparts during similar stages in life.
The term "sex recession" was popularized by journalist Kate Julian in a December 2018 cover essay for The Atlantic titled "Why Are Young People Having So Little Sex?" Julian synthesized Twenge's findings with interviews and additional data sources, arguing that the trend constituted a meaningful social phenomenon rather than a statistical blip.
In 2020, Peter Ueda of Karolinska Institutet and colleagues published an analysis in JAMA Network Open using data from the National Survey of Family Growth from 2000 to 2018.
That study extended the picture into the clinical-public-health literature and gave the discussion its most widely cited figure: roughly one in three young men aged 18 to 24 reporting no partnered sex in the prior year by the late 2010s.
How the Numbers Have Moved
The longest-running data source on American sexual behavior is the General Social Survey (GSS), conducted by NORC at the University of Chicago. Its longitudinal scope makes it the reference point for most claims about long-term change.
Weekly sexual activity among adults aged 18 to 64:
1990 | 55% |
2010 | Below 50% |
2024 | 37% |
That represents an eighteen-percentage-point decline across roughly a generation. The drop is not confined to single people.
Among married adults aged 18 to 64, weekly sexual frequency fell from 59 percent in the 1996–2008 period to 49% in 2010–2024, indicating that the recession has penetrated even the relationship form historically associated with higher sexual frequency. IFS, 2025
Sexual inactivity among young men, ages 18 to 24:
The Ueda study tracked the share of young men reporting no partnered sex in the prior twelve months. That figure rose from 18.9% in the 2000–2002 period to 30.9 percent in the 2016–2018 period.
According to the 2024 GSS data, roughly 24% of all adults aged 18 to 29 reported no sex in the past year, with rates among young men running higher than among young women. IFS, 2024
Partnership formation:
Between 2014 and 2024, the share of young adults aged 18 to 29 living with a partner, married or unmarried, fell from 42% to 32%. Since partnered individuals account for the large majority of sexual activity in any given population, this single shift explains a substantial portion of the aggregate decline. IFS, 2024

Why Researchers Think It Is Happening
No single cause is sufficient. The literature converges on a constellation of overlapping factors:
Delayed and declining partnership formation.
The median age at first marriage has risen steadily since the 1970s, and rates of cohabitation among young adults are no longer rising fast enough to compensate.
A 2021 study by Lei and South in the Journal of Marriage and Family identified trends in romantic relationship formation as one of the most statistically significant variables for declining young-adult sexual activity.
Digital displacement.
Smartphones, streaming media, social platforms, and video games compete directly for the evening hours during which partnered sex historically occurred. Pretty much everybody studying this realm is pointing a finger at screen time.
Pornography and solo sexual activity.
The Ueda study found that pornography use was associated with lower rates of sexual inactivity, which complicates the simple "porn replaces sex" narrative.
Still, readily available solo sexual outlets may reduce the perceived urgency of seeking partnered encounters. There is also the notion of a younger male generation that has programmed itself to be sexually aroused by a screen rather than physical sexual contact.
Economic and labor-market conditions for young men.
Lei and South's analysis identified declining earnings among young men and rising rates of living with parents as meaningful contributors. Economic independence is a prerequisite for forms of dating life, and the trend toward extended dependence delays the formation of sexual partnerships.
Reduced alcohol consumption.
Younger cohorts drink less than their predecessors did at the same age. Since a substantial share of casual sexual encounters has historically involved alcohol, this shift, however welcome from a public-health standpoint, mechanically reduces one pathway to sexual activity. John Hopkins
Mental health.
Rising rates of anxiety and depression among young adults, well documented in a wide variety of studies, correlate with reduced libido and reduced social initiation.
The Impact on Society
Sexual frequency is a leading indicator of broader patterns in family formation, fertility, and social connection. The downstream consequences include:
Declining fertility.
The United States crossed below replacement-level fertility in 2007 and has not recovered. While contraception and intentional childlessness are central drivers, declining sexual frequency contributes at the margin.
Delayed family formation.
Marriage, parenthood, and household formation are being pushed later in the life course, with economic and demographic effects that ripple into housing markets, labor supply, and the financing of social insurance programs.
The dating economy.
The rise of dating apps has coincided with, rather than reversed, the sex recession. Many young adults report that the apps have made casual sexual encounters easier in principle but have also concentrated sexual opportunity among a smaller subset of the most-pursued users, leaving a larger share of others with fewer partnered experiences than previous generations.

How It Is Affecting Men
The data consistently indicates that the male side of the decline is steeper than the female side, particularly at the younger ages. Several implications follow:
Not in the ideological sense of the "incel" subculture, but in the simple statistical sense: men who would prefer to be sexually active but are not.
Added social pressures, like asking a girl out, have deflected some younger men from even attempting, especially when others are recording the interaction and posting it on social media. Younger generations are less social than previous ones. Thus leading to fewer conversation attempts with the opposite sex.
Connection to the male loneliness conversation.
Survey data from the Survey Center on American Life found that 15 percent of men reported having no close friends in 2021, up from 3 percent in 1990. The sex recession overlaps with, and likely reinforces, this broader collapse in close male social ties.
Sexual confidence and mental health.
Sex therapists working with younger male clients describe a feedback loop in which delayed sexual experience produces anxiety about performance and desirability, which in turn delays further experience.
Lower testosterone levels in younger male cohorts, documented in clinical literature over the past two decades, add a physiological dimension that may interact with the behavioural one.
Asymmetric dating markets.
Women now outnumber men in college enrolment and completion, and women's stated preference for partners with equal or higher educational and economic status has not adjusted. A likely result is that a meaningful share of young men have difficulty entering the dating pool on terms acceptable to potential partners.
The political and cultural dimension.
The plight of sexually and socially disconnected young men has become one of the defining cultural stories of the 2020s, fueling everything from podcasting empires to political realignment.
Whether one views the response to that disconnection as healthy or unhealthy, the underlying demographic reality is well-attested.
A Note on Interpretation
It is worth ending where the careful researchers do. The sex recession is real in the sense that the survey numbers have moved, and moved substantially, over thirty-five years. It is contested in the sense that the magnitude depends on the cohorts examined and the dataset used. It is not uniformly bad: lower rates of casual sex correlate with lower rates of sexually transmitted infections and unintended pregnancy, and some of the decline reflects healthier individual choices. But on aggregate, the trend is consistent with other indicators of social disconnection among young men, and it is reasonable for men reading this to take it seriously as one feature of the landscape they are navigating.
