Jay: In my industry (consumer credit risk management) the term "age" is defined thus:

"Age refers only to the age of natural persons and means the number of fully elapsed years from the date of an applicant's birth." --12 CFR 202.2(d)

12 CFR 202 is the Federal Reserve Board's Regulation B: Equal Credit Opportunity. Many of the parts of the regulation that apply to my work have to do with the use of age in evaluating creditworthiness.

Is that definition used throughout the government? I bet it isn't!
