Who is the narrator in Faulkner's A Rose for Emily"?"

Faulkner's "A Rose for Emily" is a successful story not only because of its intricately complex chronology, but also because of its unique narrative point of view. Most critics incorrectly consider the narrator, who uses "we" as though speaking for the entire town, to be young, impressionable, and male; however, on close examination, we realize that the narrator is not young and is never identified as being either male or female. Who, then, is this narrator, who seemingly speaks for the town but simultaneously draws back from it? The narrator makes judgments both for and against Miss Emily, and also presents outside observations -- particularly in Section IV, when we first learn many details about her. At the beginning of the story, the narrator seems young, is easily influenced, and is very impressed by Miss Emily's arrogant, aristocratic existence; later, in Section IV, this person seems as old as Miss Emily and has related all the important things Miss Emily has done during her lifetime; and by the story's end, the narrator, having grown old with her, is presenting her with a "rose" by sympathetically and compassionately telling her bizarre and macabre story.
