In what ways are the characters in story "The Lottery" differentiated from one another?

The characters in "The Lottery" are not well rounded but are only types of people who would be found in any small American town. They are differentiated mainly by sex and age. There are little boys, adolescent boys, older men, and one old man called Old Man Warner. There are no little girls described, but there is a group of young adolescent girls who include Nancy Hutchinson and several of her friends. Most of the adult females in the story seem to be around the same age as Tessie Hutchinson, and all are typical farm wives. Two men who are differentiated by their roles in the story are Joe Summers, who is in charge of the lottery, and Harry Graves, who acts as his assistant. A man named Clyde Dunbar is differentiated from the rest of the characters by the fact that he is laid up at home outside of town with a broken leg. These characters are not brought out with any depth. They are all "types." Most readers will recognize them as people they have known at one time or another.
