http://www.associatedcontent.com/article/2696659/census_definitions_metropolitan_statistical.html?cat=37 Census Definitions: Metropolitan Statistical Areas Versus Urbanized Areas Published February 16, 2010 by: The Gator There are two different geographies that are often confused with each other. The urbanized area (UA) and the metropolitan statistical area (MSA) both refer to urban space, but they do it differently. • The UA is developed by the US Census Bureau based mainly on population density information collected during each census. The MSA is produced by the Office of Management and Budget (OMB), using information taken from the census and blended with information from other sources, primarily the Department of Labor. The primary purpose of both geographies is to provide statistical information for use by government agencies. A secondary purpose is to serve as the basis for distribution of program funds that use a formula. A wide array of federal, state, and local executive agencies use these urban definitions and delineations to allocate funding and implement regulations. Urbanized Area (UA) A n U rbanized A rea is a compact area that is entirely urban in character, defined as a contiguous area with more than 50,000 people and with a population density greater than 1,000 persons per square mile. Urban places with populations between 2,500 and 50,000 are called ―Urban Clusters.‖ The area that meets the density definition is included in the boundary of the UA, regardless of political boundaries. The "building block" of a UA is the census block group, which can be as small as one acre. Because the level of analysis is so small, UAs are often irregular in shape. Two UAs cannot share a border, because such a condition would result in a single contiguous geographic unit. According to the 2000 Census, there are 484 UAs in the United States, which cover just over 2% of the nation's land area ( 1 ).

Metropolitan Statistical Areas (MSA) Metropolitan statistical areas have a more complex definition. Counties serve as the "building blocks" of MSAs.
