Average calories produced by an adult in one hour 1712 / 5.55 = 308

Notes:

  • Production profile is PHigh and consumption profile is CLow

  • Daily work hours (column (A)) and the consumption profile (column (C)) are for individuals

  • Total daily production (column (F)) and total daily consumption (column (G)) are per population age group
