Extract
1. The existing scales of family consumption coefficients are reviewed and an attempt made to determine the sources from which they were developed. In the absence of definite information it was assumed that the majority of previous family coefficients were based upon the physiological requirements of the various age groups.
2. A family food budget survey recorded food purchased by the household. There was no guarantee that this food was eaten by the members of the house-hold in proportions similar to a scale of coefficients based upon physiological requirements.
3. Using the statistical material collected by the Commonwealth Advisory Council on Nutrition a scale of family coefficients based on calories “purchased” has been evolved by a form of statistical treatment which measured the additional food purchased for an additional person. This scale was:
This scale agrees more closely with that advanced by Lusk than any other.
4. Comparisons were drawn between the values obtained in this analysis and the physiological requirements of various age groups. It was found that for men and women and the older children the calories as purchased closely approximated to the physiological requirements, whilst for children of 2–3 years and under 2 years the former were considerably higher.
5. The protein purchased was within the range calculated to satisfy the physiological requirements.
