Food security is a determinant of health and increasingly recognized as a focus for health promotion. Led by the Population and Public Health Program, British Columbia Centre for Disease Control, this article outlines the process of development and the evidence-based conceptual framework that guides the systematic selection of food security indicators in the Province. A phased, iterative approach to develop the food security framework was adopted. Phase 1 consisted of a literature search of food security indicator models, and key informant discussions. Phase 2 consisted of modification of the model based on stakeholder consultation. The framework development occurred between January 2016 and April 2019. A structured scan of the literature found no existing conceptual frameworks specific to food security indicators in the Global North. The most relevant and frequently used frameworks for indicator reporting identified were environmental health indicator frameworks. This article presents a matrix framework based on existing environmental health indicator frameworks. It integrates environmental health causal networks (e.g., determinants-current state-impact-response) with food security elements identified as (a) individual and household food insecurity, (b) food systems, and (c) capacity. This framework contributes to food security performance monitoring in the Global North and fills an important gap in evaluating the impact of the public health response to food security. Use of this comprehensive framework can enable program planners and policy makers to be clear about where and how they are attempting to assess, influence and monitor food security, and illustrate the interconnectedness between indicators.
