Changes in households' vulnerability to food insecurity in Canada before and after the COVID-19 pandemic

The prevalence of household food insecurity in the 10 provinces rose from 16.8% in 2019 to 18.4% in 2022 and 22.9% in 2023. This study examines whether and how the sociodemographic and economic patterning of households' vulnerability to food insecurity changed across these years.

Using data from the master files for households in the 10 provinces from the 2018, 2021, and 2022 cycles of the Canadian Income Survey, year-specific logistic regression models were conducted to estimate the predicted probability of household food insecurity by sociodemographic and economic characteristics. The predicted probability of food insecurity was also charted in relation to household income from the prior tax year, expressed in 2022 constant dollars and adjusted for household size, for each survey year.

The probability of food insecurity increased significantly for most households, irrespective of the sociodemographic or economic characteristics considered. In 2019 and 2022, households receiving 50% or more of their income from employment or self-employment had a lower probability of food insecurity than those with a smaller proportion of their income from employment, but there was no difference between these groups in 2023. The probability of food insecurity was significantly higher in 2022 than 2019 at all household income levels above $20,000 and higher along the entire household income continuum in 2023 than 2022.

The probability of food insecurity is highest for low-income households, but food insecurity is becoming more prevalent among moderate- and higher-income households, and reliance on employment income is no longer protective against food insecurity.
