Minnesota Population Center 20070105 vector digital data Minneapolis, Minnesota Minnesota Population Center http://www.nhgis.org US_msacmsa_2000 This is an updated shapefile of MSA boundaries - updated from the 10/26/2006 shapefile. NHGIS staff fixed some boundaries in New England. This boundary file contains metropolitan statistical areas (MSA) for the 2000 Census of Population and Housing. The Office of Management and Budget defined MSAs in 2000 and the U.S. Census Bureau tabulated and published data for these units. The electronic boundary file was produced by the Minnesota Population Center as part of the National Historical Geographic Information System (NHGIS) project. The NHGIS is an National Science Foundation-sponsored project (Grant No. BCS0094908) to create a digital spatial-temporal database of all available historical US aggregate census materials. The available shapefiles on the NHGIS site represent version 1.0 of historical US metropolitan statistical area boundary files for the 1950-2000 censuses. These electronic census tract boundary files were created by referencing the list of SMA component parts (available at http://www.census.gov/population/estimates/metro-city/00mfips.txt) and assigning MSA FIPS codes to the NHGIS' historic 2000 county boundaries. For the MSAs in New England, we constructed towns using boundaries derived from the 2000 TIGER/Line files and assigned the correct MSA fips codes to the towns. We assumed that town boundaries did not change between 1950 and 2000. The boundary files have been checked against currently available historical census aggregate data. These data are based upon work supported by the National Science Foundation under Grant No. BCS0094908 - in infrastructure grant provided for the social sciences. Its purpose is twofold. First, the NHGIS created and freely distributes a database incorporating all available aggregate census information for the United States between 1790 and 2000. The database contains information for a wide variety of statistical (blocks, block groups, census tracts, metropolitan statistical areas) and administrative units (places, minor civil divisions, counties, states). Second, the NHGIS produced and freely distributes boundary files for small areas (census tracts and counties) in the United States. Boundary files for tracts are available for the 1910-2000 censuses, boundary files for states/territories and counties are available for the 1790-2000 censuses, and boundary files for metropolitan statistical areas are available for the 1950-2000 censuses. The Bureau of the Budget first defined county-based metropolitan areas for the 1950 Census of Population and Housing. Prior to 1950, minor civil division-based metropolitan districts were defined by the Census Bureau but were scrapped in favor of a county-based definition. Few agencies outside of the Census Bureau tabulated data at the minor civil division-level; therefore, they could not use the MCD-based districts for socioeconomic analyses. The definition of metropolitan areas has changed through time, with a major change occuring in 2002. Between 1950 and 2000, the definition was fairly stable with a few minor modifications, including name changes, through time. Essentially, a metropolitan area is "a core area containing a large population nucleus, together with adjacent communities that have a high degree of economic and social integration with that core" (U.S. Census Bureau 1994, 13-1). In 1950, the Bureau of the Budget defined standard metropolitan areas (SMAs) as "one or more counties that contain a city of 50,000 or more inhabitants, or contain a Census Bureau-defined urbanized area (UA) and have a total population of at least 100,000 (75,000 in New England). Counties containing the principal concentration of population - the largest city and surrounding densely settled area - are components...Additional counties qualify to be included by meeting a specified level of commuting to the counties containing the population concentration and by meeting certain other requirements of metropolitan character, such as a minimum population density or percentage of the population that is urban" (U.S. Census Bureau 1994, 13-1 - 13-2). In 1960, the Bureau of the Budget changed the name from standard metropolitan area (SMA) to a standard metropolitan statistical area (SMSA), which was the name until 1990, when the name was again changed to metropolitan statistical area (MSA). In 1980, standard consolidated statistical areas (SCSA) were introduced. These SCSAs are conglomerates of standard metropolitan statistical areas whose population exceeds one million people. In 1990, the Office of Management and Budget (the successor of the Bureau of the Budget) changed the names of metropolitan areas and introduced two new entities, the primary metropolitan statistical area (PMSA) and the New England County Metropolitan Area (NECMA). Standard metropolitan statistical area and standard consolidated statistical areas were changed to metropolitan statistical area (MSA) and consolidated metropolitan statistical area (CMSA). A PMSA is a "subarea...defined within an area that meets the requirements as an MSA and also has a population of one million or more" (U.S. Census Bureau 1994, 13-2). When a PMSA is defined, "the entire area of which they are parts becomes a CMSA. All territory within a CMSA is also within some PMSA" (U.S. Census Bureau 1994, 13-2). A New England County Metropolitan Area (NECMA) is a metropolitan area defined by whole counties, instead of towns or cities, in New England. More detailed information about metropolitan areas can be found in the U.S. Census Bureau's Geographic Area Reference Manual (http://www.census.gov/geo/www/garm.html) and the Bureau's website on metropolitan areas (http://www.census.gov/population/www/estimates/metrodef.html). en 2000 2000 2000 2000 2000 2000 2000 2000 2000 2000 publication date In work As work is completed -127.649716 -66.859859 51.604785 23.285329 -2337186.293564 2139181.209329 -1295866.660567 1565781.659379 None historical census of population and housing census boundaries census geography census data population housing metropolitan area standard metropolitan area metropolitan statistical area standard metropolitan statistical area consolidated metropolitan statistical area primary metropolitan statistical area None None All persons are granted a limited license to use and distribute this documentation and the available data, subject to the use constraints listed below.

The boundary file may contain more or fewer MAs than the aggregate data file. All spatial data have been reviewed to assure topological consistency and completeness. All polygons close and do not overlap. No voids exist within polygons. ArcGIS topology features classes were used to identify and fix topological errors (e.g., overlaps, voids, missing polygons) in the tract boundary datasets. The ArcGIS topology rules used to ensure logical consistency were 'Must not overlap' and 'Area Boundary must be Covered by Boundary of'. Version 1.0 of the metropolitan area boundary files contains metropolitan areas (MA). Most MAs, although not all, have a matching record in the aggregate data files. Version 1.0 boundary files have not been generalized, and tracts containing parts of the following bodies of water do not have historically accurate coastlines: the Great Lakes, Atlantic Ocean, Pacific Ocean, and the Gulf of Mexico. No tracts overlap, no voids exist between tracts, and any polygon belongs to one and only one tract. Every MAhas a FIPS-like code (GISJOIN) that uniquely identifies it. The aggregate data file contains a matching code (GISJOIN) so that the files can be easily joined together. The horizontal positional accuracy of the source data (U.S. Census Bureau TIGER/Line 2000 files) can be found at http://www.census.gov/geo/www/tlmetadata/tl2kmeta.txt. To create historic county boundaries, we used existing TIGER lines whereever possible. When no TIGER line existed, we digitized new linework from scanned and rectified U.S. Census Bureau tract maps.

These towns will serve as the boundaries of the standard metropolitan areas in New England. TGR2SHP 6.231 Imported the 1990 New England towns and cities boundaries into ArcSDE. ArcCatalog Using the 2000 MSA definition file, we merged the New England towns and cities to create New England metropolitan areas. ArcMap Converted the New England metropolitan area polygons to a line feature class. These lines were used to cut New England counties to create the metropolitan areas. ArcCatalog Copied the 2000 historical county feature class to a new feature class that will hold the 2000 metropolitan statistical areas. ArcCatalog Edited the New England counties to create the metropolitan statistical areas. ArcMap Imported the historical metropolitan area definition dBase file to an ArcSDE table. ArcCatalog Joined the historical metropolitan area definition table to the 2000 MSA feature class. This step attached the MSA codes to the appropriate counties. ArcMap Dissolve the feature class on the MSA code to create the 2000 MSA boundaries. ArcMap Created topology for the dissolved feature class with two rules ("Must not have gaps" and "Must not overlap"). If there were any errors, we edited the original feature class and then re-dissolved on the MSA code. ArcCatalog Added the GISJOIN item to the dissolved feature class and calculated it equal to the MSA code. ArcMap Wrote FGDC-compliant metadata for the 2000 MSA boundaries. ArcCatalog Exported the 2000 MSA feature class to a shapefile for Internet dissemination.

The most important attribute in this shapefile is GISJOIN because it provides the link between the shapefile and the aggregate data files. Any aggregate data file obtained through the NHGIS data acces system will contain a GISJOIN attribute. Use this attribute to link the data with the shapefile for mapping purposes. Please note that values in GISJOIN begin with "G" in order to retain leading zeros. This update took effect on May 7, 2008. GISJOIN2 is an alternative linking attribute. GISJOIN2 is similar to GISJOIN except that its values do not begin with "G". GISJOIN2 may be used when linking to an aggregate data file extracted before May 7, 2008. Other attributes in the shapefile include area (in square meters), perimeter (in meters), FID (a ArcGIS-generated unique identifier for each record), and MSA (unique FIPS code identifying the 2000 metropolitan statistical area). This shapefile contains standard metropolitan areas for the Census of Population and Housing. 20080428 20070105 As necessary Minnesota Population Center Petra Noble
