:::[Response posted on Haiduc's Talk page; repeated here for convenience of other readers:]  As attractive as "minor" at first seemed, the Wikipedia definition of the legal term "minor" proves too broad for our purposes.  Have a look at Minor_%28law%29.  Here are two quotations from that entry:  
 ::::"In law, the term minor (also infant or infancy) is used to refer to a person who is under the age in which one legally assumes adulthood and is legally granted rights afforded to adults in society. Depending on the jurisdiction and application, this age may vary, but is usually marked at either 18 or 21."   
 ::::"The age of consent for sexual activity is often lower than the age of majority, frequently using a graduated scale based on the difference in age between the participants. There is an absolute minimum age, however, varying from state to state, below which a minor may not consent. The lowest age for a legal marriage also varies by state."   
 :::Few people would consider 18- to 21-year-olds to be appropriate subjects of the article, since late adolescents are commonly thought able to consent to sexual interest from an older person (and, indeed, in many States individuals even younger than 18 are legally entitled to marry without parental permission).    
 :::"Children", despite its problems, continues to appear to me to be the best choice.  An introduction to the article could quote the Wikipedia definition of "child" and thus clarify the age range covered by the article.
