The Data Everyone Knows and Nobody Talks About

Americans are having less sex than at any point in the measured past. The General Social Survey, which has tracked sexual frequency in the United States since the 1970s, shows a consistent decline beginning in the early 2000s and accelerating after 2010. The proportion of adults who report having sex at least once a week dropped by more than ten percentage points between 2000 and 2018. The proportion reporting no sex in the past year rose substantially across all demographic groups — including married adults, which upended a lot of assumptions. The explanations offered in media are mostly cultural: smartphones, social media, the epidemic of loneliness, shifting gender dynamics, declining marriage rates. These factors are real and probably contributing. But the economic explanation is underweighted, and I think it's doing more work than it gets credit for.

The Housing Piece

Sexual frequency requires proximity. You cannot have sex with someone you can't see regularly, and you cannot maintain a relationship easily when housing costs make cohabitation difficult or impossible. This is not a trivial observation. The share of adults aged 18-34 living with parents or roommates has climbed steadily for two decades and is now at levels not seen since the Great Depression. First-time home purchase — historically a predictor of both relationship stability and cohabitation — has been delayed by an average of nearly six years compared to Boomers at the same life stage. In high cost-of-living metro areas, young adults in committed relationships frequently maintain separate residences they can't afford to consolidate. Researchers at Princeton's Woodrow Wilson School of Public and International Affairs studying family formation patterns found that economic insecurity was a stronger predictor of delayed partnership formation than stated preference — meaning the decline in young adult coupling was substantially driven by constrained resources rather than changing values. People want relationships. They're navigating conditions that make forming and maintaining them harder.

Financial Stress and Libido

Even within existing relationships, economic stress suppresses sexual frequency through well-documented physiological channels. Chronic financial anxiety elevates cortisol. Sustained cortisol elevation suppresses testosterone in both men and women. Testosterone is the primary hormonal driver of sexual desire across sexes. This is not about willpower or prioritization. It's about what chronic stress does to a body over months and years. The couple that has been underwater on their bills, working extra hours, and lying awake doing math is less likely to have sex — not because they don't want connection but because the system that generates that wanting is running at a deficit. Investigators at the Kinsey Institute at Indiana University studying sexual frequency and life stress found financial stress to be among the most potent suppressants of sexual frequency in committed relationships, ranking higher than relationship conflict, health issues, and scheduling demands in multivariate models.

Who This Affects Most

The decline in sexual frequency is not evenly distributed. Young adults without college degrees have seen sharper declines than college graduates. People in the bottom two income quintiles report lower sexual frequency and higher rates of sexual inactivity than those in the top two quintiles. These patterns follow the contours of economic precarity closely. This is consistent with a material explanation. It's also worth noting that housing cost burdens, wage stagnation, and financial insecurity have hit younger generations and lower-income Americans hardest over the past two decades. The demographic groups experiencing the greatest economic stress are the ones whose sexual frequency has declined most.

A Tangent About What Gets Blamed Instead

The internet gets a lot of credit for the sex decline. Smartphones are often offered as the primary culprit. The argument usually goes: people are spending time on screens instead of having sex. Screen time almost certainly contributes at the margins. But this explanation is too comfortable because it puts the problem entirely in the domain of individual behavior — just put the phone down. Economic explanations are more difficult because they implicate structural conditions that aren't solved by individual choices. Blame the phone, and you can talk about digital wellness. Blame housing policy and wage structure, and the conversation gets harder and less popular. The data suggests both are operating. The economic piece deserves more of the share.

What This Is Actually About

Sexual frequency is a proxy for a broader question: are people able to build the conditions — stability, proximity, energy, partnership — in which intimacy becomes possible? The data suggests that for a growing portion of Americans, particularly young and economically precarious ones, those conditions are harder to create than they used to be. That's worth taking seriously as a policy question, not just a wellness question.
