Household food insecurity risk indices for English neighbourhoods: measures to support local policy decisions

Abstract

Background: in England, the responsibility to address food insecurity lies with local government, yet the prevalence of this social inequality is unknown in small subnational areas. In 2018 an index of small-area household food insecurity risk was developed and utilised by public and third sector organisations to target interventions; this measure needed updating to better support decisions in different contexts.

Methods: we held interviews with stakeholders (n=11) and completed a scoping review to identify appropriate variables to create an updated risk measure. We then sourced a range of open access secondary data to develop an indices of food insecurity risk in English neighbourhoods. Following a process of data transformation and normalisation, we tested combinations of variables and identified the most appropriate data to reflect household food insecurity risk in urban and rural areas.

Results: eight variables, reflecting both household circumstances and local service availability, were separated into two domains with equal weighting for a new index, the Complex Index, and a subset of these make up the Simple Index. Within the Complex Index the Compositional Domain includes population characteristics while the Structural Domain reflects access to resources. The Compositional Domain is correlated well with free school meal eligibility (rs=0.705) and prevalence of childhood obesity (rs=0.641). This domain was the preferred measure for use in most areas when shared with stakeholders, and when assessed alongside other configurations of the variables. Areas of highest risk were most often located in the North of England.

Conclusion: we recommend the use of the Compositional Domain for all areas, with inclusion of the Structural Domain in rural areas where locational disadvantage makes it more difficult to access services. These measures can aid local policy makers and planners when allocating resources and interventions to support households who may experience food insecurity.
