Why do you think the war ration book requires information on a persons age sex weight height and occupation?

The war ration book likely requires information on a person's age, sex, weight, height, and occupation to assess their nutritional needs and allocate resources effectively during shortages. This data helps authorities tailor rations to different demographic groups, ensuring that individuals receive appropriate amounts of food and supplies based on their physical requirements and lifestyle. Understanding occupations also aids in prioritizing resources for essential workers, thereby supporting the war effort while maintaining public health.
