AbstractFood insecurity, inadequate access to food due to financial constraints, affects 17.3% of Canadian children, with serious health repercussions. Capitalizing on the geo-temporal variation in social policies and economic environments across Canadian provinces between 2005 and 2018, we examined the association between provincial policies and economic environments and likelihood of experiencing food insecurity among households with children. Drawn from 13 years of the Canadian Community Health Survey, our sample comprised 123,300 households with below-median income with children under 18 in the ten provinces. We applied generalized ordered logit models on the overall sample and subsamples stratified by Low-Income Measure (LIM). Higher minimum wage, lower income tax, and lower unemployment rate were associated with lower odds of food insecurity in the overall sample. A hypothetical one-dollar increase in minimum wage was associated with 0.8 to 1.0-percentage-point decrease in probability of food insecurity. The probability of food security increased by 1.2 to 1.6 percentage points following a one-percentage-point drop in bottom-bracket income tax rate. One-percentage-point lower unemployment rate corresponded to 0.6 to 0.8-percentage-point higher probability of food security. Higher welfare income and lower housing price predicted lower likelihood of severe food insecurity in the below-LIM subsample. Higher sales tax and median wage predicted higher likelihood of food insecurity among above-LIM households. Income support policies, favorable labor market conditions, and affordable living costs were all related to reduced food insecurity among Canadian households with children. Policies that increase minimum wage, reduce taxes, and create jobs may help alleviate food insecurity.Copyright © 2021 The Authors. Published by Elsevier Inc. All rights reserved.
