New Measuring Tool Reveals 17-Year Trends in Food Insecurity
A group of researchers from the Charles H. Dyson School of Applied Economics and Management have developed a groundbreaking tool for assessing food poverty in the United States. This new measuring tool, called the probability of food security (PFS), has provided valuable insights into the dynamics of food insecurity over the past 17 years.
Despite the overall prosperity and abundance of food in the US, food insecurity continues to be a significant issue. The PFS aims to estimate the likelihood that a household’s food expenses will meet or exceed the minimum cost required for a nutritious diet.
The PFS takes into account various household characteristics, such as the gender, race, and educational attainment of the household head, which have been identified as closely connected to food security. By linking these factors with food expenses, the PFS provides a comprehensive assessment of food poverty trends in the US.
What makes the PFS unique is its calibration to align precisely with the US Department of Agriculture’s Food Security Scale Score. This ensures that the tool accurately measures the prevalence of food insecurity and sheds light on the likely duration and severity of food shortage episodes.
Co-author Chris Barrett, an expert in applied economics and management, emphasizes the importance of addressing food insecurity dynamics in the US. He notes that while extensive research has been done on this topic in low-income countries, it is equally relevant in the US.
The research also reveals that certain demographic groups, such as households led by women, individuals from diverse racial backgrounds, and those with lower levels of education, are disproportionately affected by persistent or severe food insecurity. This finding allows for a more targeted approach to addressing food insecurity challenges and meeting the specific needs of these groups.
The significant findings of this research have been published in the American Journal of Agricultural Economics, marking a pivotal milestone in food security research and policy development.
In conclusion, the development of the probability of food security has provided valuable insights into food poverty trends in the US. This innovative tool enables researchers to better understand the dynamics of food insecurity and target specific demographic groups in need. Addressing food insecurity is crucial for ensuring that all Americans have access to a nutritious and healthy diet.
