Citing entire enumeration districts or cities

Hello All,     I have recently done a page by page search through two enumeration districts in the 1920 census (Pittsburgh, Ward 27). I was looking for a specific family, but did not find them. Would I cite this the same way I would normally cite a family in a census, but leave out the page, line, dwelling and name of head of the  household?                                                                                                  EXAMPLE:   1920 U.S. census, Allegheny County, Pennsylvania, population schedule, Pittsburgh Ward 27, Enumeration Districts (ED) 2-744 and 2-758, all pages, digital images, Ancestry.com (http://www.ancestry.com : accessed 14 July 2012), citing National Archives microfilm publication T625, roll 1527.                         Thanks!

Tina: Great question. Great reasoning. EE would make just a couple of tweaks:

1920 U.S. census, Allegheny County, Pennsylvania, population schedule, Pittsburgh Ward 27, Enumeration Districts (ED) 2-744 and 2-758, all pages; digital images, Ancestry.com (http://www.ancestry.com : accessed 14 July 2012), citing National Archives microfilm publication T625, roll 1527

The reason for the first tweak is that there do not exist multiple schedules for 1920.  The reason for the second tweak, the semicolon, is to make a break between the two major parts of your citation: (1) the original record; and (2) the online provider of the digital images.
