13.7% of US households were food insecure in 2024. It tracks earlier death

An estimated 13.7% of US households — about 18.3 million — were food insecure at some point during 2024, meaning they were at times uncertain of being able to afford enough food for everyone in the home, according to the US Department of Agriculture's annual measurement [s1]. That number is not just a hardship statistic: in a national cohort of 57,404 adults, those with the lowest food security died prematurely at 1.81 times the rate of the food-secure and lived, on average, about 4.5 fewer years from age 50 [s2].

The 2024 prevalence was statistically unchanged from 13.5% (18.0 million households) in 2023 [s1]. What the flat headline number hides is severity. The USDA splits food insecurity into "low" food security — coping by eating cheaper, less varied diets or using food pantries — and "very low" food security, where normal eating patterns are disrupted and intake falls because there is not enough money for food. In 2024, 8.3% of households (11.1 million) had low food security and 5.4% (7.2 million) had very low food security [s1].

The exposure is concentrated where it does the most damage

Households with children were more likely to be food insecure than the national average: 18.4% (6.7 million) reported food insecurity in 2024 [s1]. In most of those homes, adults absorbed the shortfall to shield children, but in about 0.9% of households with children — roughly 318,000 — one or more child also went without adequate food at some point in the year [s1]. Children are usually the last in a household to have their intake cut, which makes that residual figure a marker of acute deprivation rather than the whole of the problem.

What lower food security does to the body

The clearest recent evidence on outcomes comes from a 2024 cohort study in JAMA Internal Medicine that linked food-security data from the National Health and Nutrition Examination Survey (NHANES, 1999–2018) to the National Death Index through the end of 2019 [s2]. Over a median 9.3 years of follow-up, 4,263 participants died before age 80 — the study's definition of premature death. Compared with the fully food-secure, the adjusted hazard ratios for premature death were 1.50 for marginal food security, 1.44 for low, and 1.81 for very low food security, a graded relationship (p < 0.001 for trend) [s2].

Translated into life expectancy at age 50, the food-secure group could expect 32.5 more years, against 28.0 for the very-low-security group — a gap of about 4.5 years [s2]. The association was stronger in women than men: comparing very low with full food security, the hazard ratio was 2.29 in women and 1.46 in men [s2].

One mechanism is that food insecurity is not only about calories but about the quality of what a tight budget can buy. An earlier NHANES analysis of 5,094 low-income adults found food insecurity associated with clinical evidence of diet-sensitive chronic disease — an adjusted relative risk of 1.21 for hypertension and, under a stricter definition of food insecurity, 2.42 for diabetes [s3]. The pattern is consistent with the idea that the cheapest calories are often the least healthy, and that managing a chronic condition is harder when food itself is unreliable.

Association, not a clean experiment

None of this proves that food insecurity itself shortens lives. All three studies are observational, and the people who report going without food are also, on average, poorer, less securely housed, and more likely to have other disadvantages that independently damage health [s2][s3]. Food insecurity is downstream of income, so some of the mortality gap reflects the conditions that produce it rather than a direct effect of missed meals. The JAMA Internal Medicine authors adjust for a wide set of factors, but no adjustment can substitute for randomly assigning food security, which is neither feasible nor ethical.

That caveat is why the interventional evidence matters, and why it is still thin. A quasi-experimental evaluation of Medicaid-funded medically tailored meals found hospitalisations fell, but its design cannot isolate the meals from everything else that changed. The honest summary is that the correlation between food insecurity and worse health is large and consistent, while the proof that fixing the food fixes the health is still being built.

Why the economic framing is the point

Food insecurity is best read as an economic indicator with a health signature. It rises and falls with prices, wages, and the reach of assistance programmes, and it sits alongside other cost-of-living exposures — medical debt among them — that concentrate in the same households. The USDA measure is a rare, consistent, nationally representative dataset that has tracked the same question annually for three decades [s1], which is what makes it useful as a barometer of how the economy is landing on people's bodies.

What to watch

The next USDA release, covering 2025, will show whether the post-pandemic plateau holds or breaks, and it is the single most reliable place to read the food-insecurity trend rather than anecdote. The research question that would change practice is whether raising food security — through cash, benefits, or food-as-medicine programmes — measurably lowers the mortality and chronic-disease gaps that the cohort data describe. Until a well-powered trial answers it, the correlation stands, and the correlation is already stark.
