Dear Haila,
In the interests of objectivity and consistency, the Census 2000 Urban
Areas are no longer land use classifications. Parks and Industrial Areas
are no longer "Urban". The Urbanized Area is a group of contiguous
Census Blocks or Block Groups with high population density as defined by
the Census Bureau's Geographic Information System called TIGER. "Rural"
are areas of low density Census Blocks. I know it will be difficult to
explain but we just have to deal with it.
I hope this brief explanation helps.
Cheers.
