Measurement of food poverty (shoku no hinkon) as capability deprivation in high-income countries: operationalisation with single mothers in Japan.

Existing food insecurity instruments are focused largely on the financial constraints associated with acquiring sufficient amounts of food. This narrow focus has resulted in underestimating the true prevalence of food poverty, particularly in high-income countries. Food poverty needs to be defined as capability deprivation, extending from the nutritional to the temporal, spatial, qualitative and affective aspects of eating. In this article, the Alkire-Foster counting approach is evaluated and an alternative method for measuring such multidi-mensional food poverty is proposed. The method is demonstrated by using evidence from interviews with 53 single mothers, the most high-risk social group in Japan. On the basis of an operational definition of food deprivation and poverty cut-offs, 16 mothers (30%) were identified as living in food poverty, followed by a qualitative analysis of their deprivation profiles. The results show that the economically-poor were highly likely to fall into food poverty, but that food poverty also occurred without economic deprivation, notably among the mental or physical illness carriers and long-hour workers. This multidimensional and decomposable measurement tool is effective for identifying food-poor populations not reflected in traditional food insecurity measurement instruments.
