Household food insecurity is associated with both low income and high cost of living, it is a potentially better measure for consumption compared to income. We use data on food insecurity and income from 10 years of the Canadian Community Health Survey (2007-2017) of single-person households (n = 145,044) to estimate the probability of being food insecure at the Canadian poverty thresholds (Market Basket Measure thresholds, or MBMs), and determine the income required to reach that probability in each MBM region, aggregated by province and rural/urban status. A regression model shows the probability of being food insecure at the MBM is approximately 30% which we call the Food Insecurity Poverty Line (FIPL). The income required to meet the FIPL is substantially different from the MBM, sometimes 1.25 times the MBM. This implies that food insecurity is a potential sentinel measure for poverty.
家庭粮食不安全与低收入和高生活成本有关，与收入相比，它是一种更适合衡量消费的潜在指标。我们使用 10 年来加拿大社区健康调查（2007-2017 年）中单户家庭（n=145044）的粮食不安全和收入数据，来估计在加拿大贫困线（市场篮子衡量标准或 MBM）下处于粮食不安全状态的概率，并确定在每个 MBM 地区达到该概率所需的收入，按省份和城乡状况进行汇总。回归模型显示，处于 MBM 下的粮食不安全的概率约为 30%，我们称之为粮食不安全贫困线（FIPL）。要达到 FIPL 所需的收入与 MBM 有很大的不同，有时是 MBM 的 1.25 倍。这意味着粮食不安全是贫困的一个潜在哨兵指标。
