Food Insecurity Index values for the years 2021 to 2023 are still valid. The index model used to calculate values for those years is based on a strong correlation between four economic and household hardship indicators and poor food access (Conduent HCI Food Insecurity Index 2020 Methodology).
In 2024, Conduent HCI updated our methodology for the index to consider our current library of indicators with consideration of more recent studies and publications about factors impacting food insecurity.
