Nutrition, crowding and disease among low-income households in Tokyo in 1930

This article employs a household survey of low-income working-class households conducted in Tokyo in 1930 to investigate nutritional attainment levels and the relationship between calorie intake and morbidity. We find that the daily calorie intake was 2,118 kcal per adult male equivalent, high enough to satisfy the energy requirements for moderate physical activity. Richer households purchased more expensive calories mainly by substituting meat and vegetables for rice. We find negative associations between morbidity and income and crowding, but no significant associations for nutrition, tentatively suggesting that income and crowding were more important for morbidity in 1930 Tokyo than nutrition.
