National Metropolitan Statistical Areas Polygons |
All node-link and polygon topological relationships are created and verified using ARC/INFO. Unique entity identifiers were similarly verified using ArcGIS. |
The Metropolitan Statistical Areas database was compiled from TIGER/Line data with a corresponding positional accuracy of +/- 80m for the contiguous 48 States plus Washington D.C. and Hawaii. TIGER/Line files for Puerto Rico and Alaska are at a scale of 1:125,000. The shorelines for the 23 coastal states were created using 1:250,000 NOS digital data which has a positional accuracy of +/- 200m. Thus, all internal political boundaries have a higher accuracy than do the coastal definitions with the exception of Puerto Rico and Alaska. |
GeoPlan relied on the integrity of the attribute information within the original data. |
The general concept of a metropolitan area (MA) is one of a large population nucleus, together with adjacent communities that have a high degree of economic and social integration with that nucleus. Some MAs are defined around two or more nuclei. Each MA must contain either a place with a minimum population of 50,000 or a U.S. Census Bureau-defined urbanized area and a total MA population of at least 100,000 (75,000 in New England). An MA contains one or more central counties. An MA also may include one or more outlying counties that have close economic and social relationships with the central county. An outlying county must have a specified level of commuting to the central counties and also must meet certain standards regarding metropolitan character, such as population density, urban population, and population growth. In New England, MAs consist of groupings of cities and towns rather than whole counties. The territory, population, and housing units in MAs are referred to as "metropolitan." The metropolitan category is subdivided into "inside central city" and "outside central city." The territory, population, and housing units located outside territory designated "metropolitan" are referred to as "non-metropolitan." The metropolitan and non-metropolitan classification cuts across the other hierarchies; for example, generally there are both urban and rural territory within both metropolitan and non-metropolitan areas. |
The data provide users with information about the locations, names, and sizes of MSAs primarily for national planning applications. The MA(s) and the central cities within an MA are designated and defined by the federal Office of Management and Budget (OMB), following a set of official standards that are published in a Federal Register Notice. The interagency Federal Executive Committee on Metropolitan Areas developed these standards, with the aim of producing definitions that are as consistent as possible for all MA(s) nationwide. |

THE DATA INCLUDED IN FGDL ARE 'AS IS' AND SHOULD NOT BE CONSTRUED AS LEGALLY BINDING. THE UNIVERSITY OF FLORIDA GEOPLAN CENTER SHALL NOT BE LIABLE FOR ANY DAMAGES SUFFERED AS A RESULT OF USING, MODIFYING, CONTRIBUTING OR DISTRIBUTING THE MATERIALS. A note about data scale: Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation.

All state supplied maps were digitized. MSA boundaries were added from TIGER data and topologically integrated. The data were checked for completeness and accuracy and were extracted and reformatted into ASCII data files. These were then converted to ESRI shapefiles. Process Date: Unknown |
