Thank you all for your helpful answers,  I have two or three exactly the same answers and 6 references to sources.  This is obviously the go to listserv for tough census questions.

Subject: [CTPP] population of urbanized area

I don't like to ask for information that I can find by just looking, but I have looked all over the US Census web site and the BTS website for the -
population of urbanized areas, specifically the Grand Rapids, Michigan urbanized area, 1990
But I cannot find it.  Can anyone direct me to a source?  Thanks.  Jay Hoekstra
