Googling quickly brings up http://www.cnpp.usda.gov/Publications/NutritionInsights/insight11.pdf

Serving size is defined as follows:

  1. Amount of foods from a food group typically reported in surveys as consumed on one eating occasion;
  2. Amount of foods that provide a comparable amount of key nutrients from that food group, for example, the amount of cheese that provides the same amount of calcium as 1 cup fluid milk;
  3. Amount of foods recognized by most consumers (e.g., household measures) or that can be easily multiplied or divided to describe a quantity of food actually consumed (portion);
  4. Amount traditionally used in previous food guides to describe servings.

While the amount of food people would eat is not the only factor used, it's a major one.
