The\nIndian Health Service Standard Codebook Community table was constructed from\nmultiple reference tables containing approved code sets in the General Data\nMart (GDM), specifically the community, county, and state tables. In\n2007, <\/span>Dr. L. Layne with contributions from Kirk Greenway in\nthe IHS Office of Public Health Support designed a SAS program to join\nthese separate GDM tables together to derive the "IHS community"\ntable populated with information in the Standard Codebook Community table. <\/span>The Geographic\nNames Information System (GNIS) dataset <\/span>containing information\nabout the official names for places in the United States and their associated\ncoordinates was also obtained from the U.S. Geological Survey website to assign\neach IHS community a pair of point coordinates.<\/span><\/span><\/p>\n\n

Another\nSAS program was then created to join records from the IHS Communities\nderived table and the GNIS table to assign point coordinates to the communities\nfrom the IHS Standard Codebook community table. This was performed by comparing\na community name between the two tables where the state and county FIPS were\nrequired to match. The value in "FEATURE_CLASS" was further examined\nto assign coordinates according to a hierarchical list of preferred location.\nFor example, if the value in FEATURE_CLASS was Populated Place, those\ncoordinates were assigned to the IHS community. If not, another class was\nchosen. The coordinates assigned based on the values in FEATURE_CLASS were\nselected with the following priorities: Populated Place, Locale, and the first\nthat matched the community name the program was searching for.  Locations\nfor matched community name and county FIPS were used to assign a coordinates to\nan IHS Community.<\/span><\/span><\/p>\n\n

Communities\nthat did not have coordinates assigned to them were output to a separate data\ntable. Community names were cleaned for incorrect spelling, odd abbreviations\nor name truncation due to field length restrictions. The corrected community\nnames were used to populate the "community name" field. \nLocations for these communities were then compared to the GNIS data table again\nand assigned  coordinated to matched communities. <\/span><\/span><\/p>\n\nIHS Communities Version 2021-04.0 Description<\/span>\n\n

IHS\nCommunities Version 2021-04.0 contains additional fields/columns and data\ngiving users the option to refine the list of IHS communities by selecting\ncommunities based on their proximity to federally-recognized tribal lands,\nincluding federal Indian reservations, Indian trust-lands, off-reservation\ntrust lands, rancherias, colonies, pueblos, joint-use areas, Alaska Native\nvillage statistical areas (ANVSAs<\/i>), Oklahoma tribal statistical areas (OTSAs<\/i>),\nand tribal designated statistical areas (TDSAs<\/i>). <\/span><\/span><\/p>\n\n

IHS\nCommunities Version 2021-04.0 excludes inactive communities and\ncommunities that fall within states not actively served by the IHS: Arkansas,\nDelaware, Georgia, Indiana, Kentucky, Missouri, New Hampshire, New Jersey,\nOhio, and West Virginia.<\/span><\/span><\/p>\n\n

The IHS\ncommunity point layer is one of IHS's four-core spatial datasets to facilitate\nthe analysis of epidemiology and health geography to improve health outcomes\nfor American Indians and Alaska Natives. The IHS GIS Team continually\nupdates, removes, and assigns coordinates to new communities listed in the\nIHS Standard Codebook Community table. <\/span><\/span><\/p>\n\n
