Ill SYMBOLS AND GEOGRAPHIC ABBREVIATIONS Ill GENERAL This report presents statistics from the 1980 Census of Population on the num- ber of inhabitants of the Area, its sub- divisions, places, and certain other geographic areas. The abbreviated identi- fication for this report is PC80-1-A (i.e., Population Census, 1980-Volume 1- Chapter A) followed by a number repre- senting the Area. Legal provision for this census, which was conducted as of April 1, 1980 (September 15, 1980 for the Trust Territory of the Pacific Islands, excluding the Northern Mariana Islands) was made in the Act of Congress of August 31, 1954 (amended August 1957, December 1 975, and October 1 976) which codified Title 13, United States Code. A large portion of the information compiled from the 1980 Census of Population will appear in Volume 1, Characteristics of the Population, of which this report is part. For Guam, the Virgin Islands of the United States, and American Samoa, the 1980 census figures presented may dif- fer from those shown in the Advance Reports, PHC80-V. The changes reflect corrections of errors found after the PHC80-V report was prepared and may affect any geographic area shown in this report. For the Northern Mariana Islands and the remainder of the Trust Territory of the Pacific Islands, the 1980 census figures presented are final counts and supersede the preliminary counts pub- lished for each Area. The content and procedures of the 1980 census were determined after evalu- ation of the results of the 1970 census and consultation with a wide variety of users of census data. A number of changes were introduced in 1980 to improve the usefulness of the census results. The changes, however, do not affect to any appreciable extent the comparability between the 1980 data and the 1970 data shown in this report. More detailed information on the technical and procedural matters covered in the text of this report can be obtained by writing to the Director, Bureau of the Census, Washington, D.C. 20233. Such information will also appear in other publications of the 1980 census. CONTENTS OF THE REPORT This report contains a text (this intro- duction and three appendixes), a table of contents, 13 detailed tables, and maps. A general location map and a map of the Area appear after the table of contents. Each table is identified by a table number and title. The "stubhead" at the left under the title defines the types of geographic areas for which data are shown in the particular table and is considered part of the table title. The tables are followed by a map section which includes: • An "Island Location Index" which presents the reference coordinates for each island on the subdivision map and the legend to that map. • A one-page island subdivision map that shows the names of the islands, the names and boundaries of island sub- divisions (census subdistricts), and places, as recognized by the Census Bureau in the published tables. Appearing last in the report are the appendixes. Appendix A describes the various area classifications (e.g., urban and rural residence, minor civil divisions, places). Appendix B explains the residence rules used in counting the population and describes the data col- lection and processing procedures. Appendix C presents information on the sources of error in the data. SYMBOLS AND GEOGRAPHIC ABBREVIATIONS The following symbols and geographic abbreviations are used in the tables: • A dash "-" represents zero or a percent which rounds to less than 0.1. • Three dots ". . ." mean not applicable. • (NA) means not available. • A minus sign preceding a figure denotes decrease. • The prefix " r " indicates that the count has been revised since the publication of 1970 census reports, or that the area was erroneously omitted, or that the area was not shown in the correct geographic relationship in the 1970 census reports. • CDP is census designated place. • SMSA is standard metropolitan statis- tical area. • (unorg.) is unorganized territory.

Puerto Rico, Guam, the Virgin Islands of the United States, American Samoa, the Northern Mariana Islands, and the remainder of the Trust Territory of the Pacific Islands are treated as State equiva- lents in the text and tables of the PC80-1-A reports. COUNTY EQUIVALENTS In most States, the primary divisions are termed counties. In the Virgin Islands of the United States, the comparable areas are the three major islands. In American Samoa, the county equivalents are three districts and two islands. In Guam and the Northern Mariana Islands, there are no primary divisions, and the entire area is considered equivalent to a county for census purposes. In the Trust Territory of the Pacific Islands, excluding the Northern Mariana Islands, the adminis- trative districts are the county equivalents. COUNTY SUBDIVISION EQUIVALENTS In reports for the States, statistics are presented for the following subdivisions of counties or equivalent areas: minorcivil divisions (MCD's), census county divisions (CCD's), and, in Alaska, census subareas. In Guam, the Virgin Islands of the United States, American Samoa, the Northern Mariana Islands, and the remainder of the Trust Territory of the Pacific Islands, statistics are presented for minor civil divisions and, in the Northern Mariana Islands and the remainder of the Trust Territory of the Pacific Islands, for sub- divisions of the minor civil divisions. Minor Civil Divisions (MCD's) In 29 States, MCD's are primary divisions of counties established under State law. MCD's in Guam, the Virgin Islands of the United States, American Samoa, the Northern Mariana Islands, and the remain- der of the Trust Territory of the Pacific Islands have been established by local law. The MCD's in Guam are referred to as election districts. In the Virgin Islands of the United States, MCD's called census subdistricts have been established for the 1980 census to replace the quarters and cities that were used in the 1970 census. For American Samoa, the three districts are subdivided into MCD's called counties; MCD's for the two islands coincide with and have the same names as these islands. The MCD's in the Northern Mariana Islands are called municipalities. The MCD's in the remainder of the Trust Territory of the Pacific Islands are municipalities. In addition, the Census Bureau recognizes two islands and one unorganized territory that are not within any municipality. In the Palau District of the Trust Territory of the Pacific Islands, numerous islands are not included in a legally established MCD (municipality); this area of unorganized territory is recog- nized as one subdivision and given a name (Palau Islands) by the Census Bureau, followed by the designation "(unorg.)." Subdivisions of MCD's In the Northern Mariana Islands and the remainder of the Trust Territory of the Pacific Islands, subMCD's, called munic- ipal districts, represent political subdi- visions of the municipalities. Some are true political entities while others have been established for census purposes. Data are shown only for municipal districts in multi-district municipalities. PLACES Two types of places are recognized in the State census reports—incorporated places and census designated places—as defined below. Incorporated Places Incorporated places recognized in the State census reports are those which are incorporated under the laws of their re- spective States as cities, boroughs, towns, and villages. There are no incorporated places in Guam, the Virgin Islands of the United States, American Samoa, the Northern Mariana Islands, and the remain- der of the Trust Territory of the Pacific Islands. Towns in the Virgin Islands of the United States and Villages in American Samoa are not legally incorporated. The three places specified as towns in the Virgin Islands Code have legally established boundaries and purposes, but are not functioning governments. The villages in American Samoa have functioning governments authorized by the Revised A-1 Appendix A.—Area Classifications Code of American Samoa but do not have legally established boundaries. Census Designated Places As in previous censuses, the Census Bureau, in cooperation with local govern- ments, delineated boundaries for closely settled population centers without corpo- rate limits. In 1980, the name of each such place is followed by "(CDP)," meaning "census designated place." For 1980, all places in Guam are designated as CDP's; in 1970 and earlier censuses, these places were identified in census publications as cities, towns, and villages. In the Virgin Islands of the United States, six CDP's have been designated. All places in the Northern Mariana Islands and the remainder of the Trust Territory of the Pacific Islands are CDP's. To be recognized for the 1980 census, CDP's in Guam, the Virgin Islands of the United States, the Northern Mariana Islands, and the remain- der of the Trust Territory of the Pacific Islands must have a minimum 1980 popu- lation of 300. There are no CDP's in American Samoa. Census designated place boundaries change as the settlement pattern changes; a place which has the same name as in previous censuses does not necessarily have the same boundaries. Boundary out- lines for CDP's are shown on the map which follows the detailed tables. Larger- scale maps, showing boundaries in more detail, are available for purchase from the Census Bureau. URBAN AND RURAL RESIDENCE As defined for the 1980 census, the urban population comprises all persons living in urbanized areas and in places of 2,500 or more inhabitants outside urbanized areas. More specifically, the urban population consists of all persons living in (1) places of 2,500 or more inhabitants and (2) other territory included in urbanized areas. The population not classified as urban constitutes the rural population. Since there are no urbanized areas in Guam, the Virgin Islands of the United States, American Samoa, the Northern Mariana Islands, and the remainder of the Trust Territory of the Pacific Islands, the current definition of urban population is equivalent to the previous definition. That A-2 is, the urban population comprises all per- sons living in places of 2,500 or more inhabitants. URBANIZED AREAS The major objective of the Census Bureau in delineating urbanized areas is to provide a better separation of urban and rural population in the vicinity of large cities. An urbanized area consists of a central city or cities, and surrounding closely settled territory ("urban fringe"), which contains a minimum population of 50,000. There are no urbanized areas in Guam, the Virgin Islands of the United States, American Samoa, the Northern Mariana Islands, and the remainder of the Trust Territory of the Pacific Islands. STANDARD METROPOLITAN STATISTICAL AREAS The general concept of a metropolitan area is one of a large population nucleus —an urbanized area with a population of at least 50,000—together with adjacent communities which have a high degree of economic and social integration with that nucleus. The standard metropolitan sta- tistical area (SMSA) classification is a statistical standard developed for use by federal agencies in the production, analysis, and publication of data on metropolitan areas. SMSA's are desig- nated and defined by the Office of Management and Budget, following a set of official published standards developed by the interagency Federal Committee on Standard Metropolitan Statistical Areas. There are no SMSA's in Guam, the Virgin Islands of the United States, Amer- ican Samoa, the Northern Mariana Islands, and the remainder of the Trust Territory of the Pacific Islands. BOUNDARY CHANGES The boundaries of some of the areas shown in this report have changed between an earlier census for which counts are shown and January 1, 1980. The historic counts shown here have not been adjusted for such changes and thus reflect the population in those areas as defined at each census. Information on boundary changes is presented in table 4. For information on boundary changes prior to 1970 for Guam, the Virgin Islands of the United States, and American Samoa, see the Number of Inhabitants report for previous censuses. AREA MEASUREMENTS Area measurement figures published in the 1980 census for each entity and its districts or islands are taken from the data used for the 1970 census. Appro- priate modifications were made to account for changes in boundaries, the establishment of new geographic units, and for errors in the earlier figures. HISTORIC COUNTS As in past censuses, the general rule for presenting historic figures for each area is to present counts only for single, con- tinually existing entities. Stated another way, if an area existed at both the current and previous censuses, a count is shown for the previous census. Included in this category are areas which are of the same type and which have retained the same name, or which may have changed their name. Also included are places which have merged and retained the name of one of the merged areas. In cases where entities have been formed since, or were not recognized in the earlier censuses, such as a new district, district subdivision, or place, the symbol three dots (". . .") is shown for the earlier census. The three-dot symbol is also shown for those parts of a place which are now located in an entity in which it was not previously reported. In a number of tables in this report, 1970 counts are shown for aggregations of individual areas, such as the number and population of places by size groups or urban and rural distributions. In some instances, population counts for individual areas have been revised since publication of the 1970 census reports (indicated by the prefix "r" as described in the section "Symbols and Geographic Abbreviations" in the Introduction). These revisions have not been carried through to the various aggregations; therefore, it may not be possible to determine the individual areas in a given aggregation using the 1970 population counts shown here.

B-2 USUAL PLACE OF RESIDENCE In accordance with census practice, each person enumerated in the 1980 census was counted as an inhabitant of his or her "usual place of residence," which is generally construed to mean the place where the person lives and sleeps most of the time. This place is not necessarily the same as the person's legal residence or voting residence. In the vast majority of cases, however, the use of these different bases of classification would produce substantially the same statistics, although there might be appreciable differences for a few areas. The implementation of this practice has resulted in the establishment of residence rules for certain categories of persons whose usual place of residence is not immediately apparent. Furthermore, this practice means that persons were not always counted as residents of the place where they happened to be staying on Census Day. Persons without a usual place of residence, or persons with no one at their usual place of residence to report them to a census taker, however, were counted where they happened to be staying. U.S. Armed Forces Members of the U.S. Armed Forces living on a military installation were counted, as in previous censuses, as residents of the area in which the instal- lation was located; members of the U.S. Armed Forces not living on a military installation were counted as residents of the area in which they were living. Persons in families with U.S. Armed Forces personnel were counted where they were living on Census Day (i.e., the military installation or "off base," as the case might be). Each U.S. Navy ship was attributed to the geographic area that the Department of the Navy designated as its homeport. Crews of Merchant Vessels Crews of merchant ships berthed in a port, excluding those not flying a U.S. flag, were enumerated as of that port. Persons Away at School College students were counted as residents of the area in which they were living while attending college. However, children in boarding schools below the college level were counted at their parental home. Persons in Institutions Inmates of institutions were counted as residents of the area where the institution was located. Patients in short-term wards of general hospitals were counted at their usual place of residence; if they had no usual place of residence or there was no one at their usual place of resi- dence to report them, they were counted at the hospital. Persons Away From Their Residence on Census Day Persons in hotels, motels, etc., on the night of March 31, 1980 (September 12, 1980 for the Trust Territory of the Pacific Islands, excluding the Northern Mariana Islands), having their usual home within the Area and who indicated that no one was at home to report them in the census were enumerated as residents of the hotel, motel, etc. Information on persons away from their usual place of residence was obtained from other members of their families, resident managers, neighbors, etc. If an entire household was away during the whole period of the enumeration, information on that household was obtained from neighbors. In the Virgin Islands of the United States, the part of the procedures relating to the enumeration of persons staying in hotels and motels was not feasible because of the large number of guests in the islands during the local festivities that took place around Census Day. This should not have any significant effect in the total popula- tion counts, since persons staying at hotels and motels during this period were generally not residents of the area, and even if they were, someone at home would have reported them to a census taker. Residents Abroad Residents who were abroad for an ex- tended period (in the Armed Forces, working at civilian jobs, studying in uni- versities outside the Area, etc.) were not included in the population of the Area. On the other hand, residents who were temporarily abroad on vacations, business trips, and the like, were counted at their usual residence in the Area. Persons From Other Areas Persons from other areas, having their usual residence (legally or illegally) in this Area on Census Day, including those work- ing here and those attending school (but not living at a chancellery or consulate) were included in the enumeration, as were members of their families living with them, B-1 Appendix B.—General Enumeration and Processing Procedures regardless of citizenship. However, persons from other areas, temporarily visiting or traveling in this Area, were not enumerated in the 1980 census. DATA COLLECTION PROCEDURES The 1980 census of Guam, the Virgin Islands of the United States, American Samoa, the Northern Mariana Islands, and the remainder of the Trust Territory of the Pacific Islands was conducted through direct interview. Beginning on Census Day, April 1, 1980 (September 15, 1980 for the Trust Territory of the Pacific Islands, excluding the Northern Mariana Islands), enumerators visited and listed every household, asking the questions as worded on the questionnaire, and recording the answers. A single ques- tionnaire was used, which contained all the questions asked of every person and household. Special questionnaires were used for the enumeration of persons in group quarters such as colleges and universities, hospitals, and prisons. These forms con- tained the same population questions that appeared on the regular census ques- tionnaire, but did not include any housing questions. PROCESSING PROCEDURES The 1980 census questionnaires were processed in a manner similar to that for the 1970 census. They were designed to be processed electronically by the Film Optical Sensing Device for Input into Computer (FOSDIC). For most items on the questionnaire, the information obtained by the enumerator was recorded by marking the answers in the predesig- nated positions that would be "read" by FOSDIC from a microfilm copy of the questionnaire and transferred onto computer tape with no intervening manual processing. The computer tape excluded information on individual names and addresses. The tape containing the information from the questionnaires was processed on the Census Bureau's computers through a number of editing and tabulating steps. Among the products of this operation were computer tapes from which the tables in this report (and most others in the 1980 census publications) were pre- pared on phototypesetting equipment at the Government Printing Office. A more detailed description of the data collection and processing procedures can be obtained from the 1980 Census of Population and Housing, Users' Guide, PHC80-R1. B-2 Appendix C— Accuracy of the Data Since 1980 population counts shown in this report were tabulated from the entries for persons on all questionnaires, these counts are not subject to sampling error. In any large-scale statistical opera- tion such as a decennial census, human and mechanical errors occur. These errors are commonly referred to as nonsampling errors. Such errors include failure to enumerate every household or person in the population, not obtaining all required information from respondents, obtaining incorrect or inconsistent information, and recording information incorrectly. Errors can also occur during the field review of the enumerators' work, the clerical handling of the census questionnaires, or the electronic processing of the questionnaires. In an attempt to reduce various types of nonsampling error in the 1980 census, a number of techniques were introduced on the basis of experience in previous censuses and in tests conducted prior to the census. These quality control and review measures were utilized throughout the data collection and processing phases of the census to minimize undercoverage of the population and housing units and to keep the errors at a minimum. *O.S.
