since the United States Department of Agriculture (USDA) first began report- ing its official food security measure in 1995. Te authors study household food security dynamics in the United States from 2001 to 2017 using a new measure, the probability of food security (PFS), to analyze household-level and subpopulation-scale dynamics by investigating the conditional distribu- tion of estimated food insecurity spells and the chronic and transient compo- nents of estimated food insecurity.


By this metric, the authors find that two-thirds of households experienced no estimated food insecurity during the 2001 to 2017 period and more than half of newly food insecure households regain food security within two years. Households headed by female, non-White, or less educated individuals disproportionately suffer persistent, chronic, and/or severe food insecurity. Given the adverse effects on a host of economic, health, and social outcomes, and those outcomes’ feedback on household incomes, dietary behaviors, and subsequent food security status, a sound understanding of household-scale food security dynamics can help with effective policy design and evaluation.
