A setting in any writing includes both a time and place for where the action of the text takes place. A setting can be rather general or very specific. Settings can take place in the past, present, future, or in any combination of. The geographical location of a text can be real, imaginary, small, or vast.
Sandra Cisneros' The House on Mango Street provides readers with a solid geographical place: a Hispanic American ghetto in Chicago (the neighborhood which surrounds Esperanza's house). The action of the text takes place over the course of one year.
Although readers are not given a specific time-line for when the text takes place, one could suggest that it could take place in the 1970s (when it was written) as easily as it could take place today.
