NOTE: The filling of codes and data attributes in the files is specific to summary level; not all fields are filled for every summary level. Where a code or attribute is specified, the actual value is assigned to the field except for the use of three special codes:

Assignment of codes of nine (9) indicates a balance record or that the entity or attribute does not exist for this record.

Assignment of pound signs (#) indicates that more than one value exists for this field and, thus, no specific value can be assigned.

Assignment of exclamation marks (!) indicates that this value has not yet been determined for this file.

2. Identifies the geographic level for which the data matrices on the summary file have been summarized. The summary level sequence chart describes the hierarchical arrangement of the specified geographic areas with other geographic areas, if any. The summary level must be used in combination with the geographic area codes to identify a specific geographic area (for example, summary level 050 and a specific county code must be used together to locate the data for a particular county). See How to Use This File for further information.
3. Indicates an iteration (repetition), for the specified summary level, of the data matrices on the summary file for the geographic components listed in the Geographic Component field. See How to Use This File for further information.

4. Indicates an iteration (repetition), for the specified summary level, of the data matrices on the summary file for a population or housing characteristic. These iteration fields apply to SF 2 and SF 4 only. See How to Use This File (Chapter 2) for further information.
5. The logical record is the complete record for a geographic entity defined by the summary level, but exclusive of the characteristic iteration. A logical record may have one or more parts(or segments). Each logical record has an assigned sequential integer number within the file.
See How to Use This File for further information.
6. See Appendix A, Census 2000 Geographic Terms and Concepts, for definition of this field.
7. Federal Information Processing Standards (FIPS) codes are standards and guidelines that are issued by National Institute of Standards and Technology (NIST) for use in computer systems within the federal government. There are several standards used in Census 2000 data presentation.
The Census Bureau maintains the following standards:
FIPS 5, Codes for the identification of the states, the District of Columbia, and the Outlying Areas of the United States, and associated areas
FIPS 6, Counties and equivalent entities of the United States, its possessions, and associated areas
FIPS 9, Congressional Districts of the United States
The Office of Management and Budget (OMB) maintains:
FIPS 8, Metropolitan Areas (Including MSAs, CMSAs, PMSAs, and NECMAs)
The United States Geological Survey (USGS) maintains:
FIPS 55, Guideline: Codes for Named Populated Places, Primary County Divisions, and Other Locational Entities of the United States, Puerto Rico, and the Outlying Areas General information about FIPS can be found on the Internet at:
http://geonames.usgs.gov/
The actual codes assigned to the many FIPS 55 entities can be found at:

8. Codes in unspecified arrangement for U.S. Census Bureau use.
9. For summary levels 256, 257, 258, 259, 289, 291, 292, 293, and 294, the Census Bureau only creates records for federally recognized American Indian reservation and/or off-reservation trust land entities, as appropriate for the summary level. No records are created for state reservations, statistical American Indian and Alaska Native areas, and Hawaiian home lands.
10. Federal Information Processing Standards (FIPS) 55 codes are assigned by state. Because American Indian areas can exist in more than one state, multiple FIPS 55 codes exist for the entity. In National products, American Indian areas in multiple states will show a FIPS 55 code of '#####' indicating that multiple FIPS codes exist for this entity.
11. State legislative district codes can have one to three characters including special characters of dashes, slashes, and periods. If the code contains less than three characters, the field is right justified with leading blanks.
12. Voting district codes can have one to six characters including special characters of dashes, slashes, and periods. If the code contains less than six characters, the field is right-justified with leading blanks
13. Land area measurement in square meters. The accuracy of the area measurement is limited by the inaccuracy inherent in the mapping of the various boundary features in the TIGER® file. Land area includes intermittent water and glaciers, which appear on census maps and in the TIGER file as hydrographic features. Square miles can be derived by dividing square meters by 2,589,988. See Appendix A, Census 2000 Geographic Terms and Concepts, for definition of this field if it is applicable to this file.
14. Water area measurement in square meters. The accuracy of the area measurement is limited by the inaccuracy inherent in the mapping of the various boundary features in the TIGER File. Water area excludes intermittent water and glaciers, which are treated as land even though they appear on census maps and in the TIGER File as hydrographic features. Square miles can be derived by dividing square meters by 2589988. See Appendix A, Census 2000 Geographic Terms and Concepts, for definition of this field if it is applicable to this file.
15. Name of the lowest-level entity represented by the summary level. In addition to the name of the entity, the name field contains the legal/statistical area description (LSAD) when appropriate, and sometimes contains the state abbreviation. For legal entities, the name is the one reported to the U.S. Census Bureau in the Boundary and Annexation Survey or by other appropriate sources. For statistical entities, the name is determined by the Office of Management and Budget for metropolitan areas. For other areas, the name is determined by the local officials, usually in cooperation with the U.S. Census Bureau. When the summary level represents only part of the area specified in the name, the name usually will have "(pt.)" appended to the name/code terminology to designate that this entry for the entity represents only a part of the total entity.
16. The total number of persons enumerated in the specified summary level as determined in the 100-percent processing.
17. The total number of housing units enumerated in the specified summary level as determined in the 100-percent processing.
18. Latitude in degrees, to six decimal places, of a point within the geographic area represented by the summary level. The decimal point is implied on the file. The character immediately preceding the first digit of the latitude of an internal point identifies the direction (hemisphere): a plus sign (+) indicates the Northern Hemisphere; a minus sign (-) indicates the Southern Hemisphere. See Appendix A, Census 2000 Geographic Terms and Concepts, for definition of this field if it is applicable to this file.
19. Longitude in degrees, to six decimal places, of a point with the geographic area represented by the summary level. The decimal point is implied on the file. The character immediately preceding the first digit of the longitude of an internal point identifies the direction (hemisphere): a plus sign (+) indicates the Eastern Hemisphere; a minus sign (-) indicates the Western Hemisphere. A point on the 180th meridian is assigned to the Western Hemisphere (-180000000). See Appendix A, Census 2000 Geographic Terms and Concepts, for definition of this field if it is applicable to this file.
