Urban Area
Urban Area means an area containing a city (or its equivalent), or any equivalent geographic area determined by the Census Bureau and adopted by the Agency for purposes of this definition (about which the Agency will publish a document in the Federal Register from time to time), which had a population of over 150,000 in the most recent decennial Census and the urbanized areas containing or adjacent to that city, both as determined by the Bureau of the Census for the most recent decennial Census.
