The population and housing subjects in this file are listed below. Data are presented in 86 population tables and 35 housing tables. Selected medians and means also are included. Each table is identified with a two-character prefix, based on the U.S. postal abbreviation for the Island Area, followed by a sequential number. In “Chapter 6: Data Dictionary,” the table numbers and titles, applicable universes, detailed subject content, and other information for each table are provided. Population subjects include: Age Marital status Children ever born (fertility) Nativity Citizenship status Occupation Class of worker Parents’ place of birth Disability status Place of birth Earnings in 2009 Place of work Educational attainment Poverty status in 2009 Employment status and subsistence activity Reason for moving Ethnic origin or race Remittances sent abroad in 2009 Family type Residence in 2009 (migration) Foreign-born status School enrollment Grandparents as caregivers Service-connected disability status Group quarters population and ratings Health insurance coverage status Sex Household type and relationship Travel time to work Income in 2009 Veteran status Industry Vocational training Journey to work (commuting) Work experience Language spoken at home and Year of entry frequency of language usage Abstract 1-1 U.S. Census Bureau, 2010 Census Commonwealth of the Northern Mariana Islands Demographic Profile Summary File Housing subjects include: Air conditioning Selected monthly owner costs Battery-operated radio Sewage disposal Computer ownership Source of water Gross rent Telephone service available Internet service Tenure Kitchen facilities Type of building materials Mortgage status Units in structure Number of bedrooms Vacancy status Number of rooms Value of home Occupancy status Vehicles available Occupants per room Year householder moved into unit Plumbing facilities Year structure built GEOGRAPHIC CONTENT The Demographic Profile Summary File is released as an individual file for the Commonwealth of the Northern Mariana Islands.

USER UPDATES User updates inform data users about corrections, errata, and related explanatory information. These updates provide information about unique characteristics, changes, and corrections. However, sometimes this information becomes available too late to be reflected in the product or related documentation.

Novice users trying to understand how to use the documentation and the file should read this chapter first. DATA FORMAT AND ACCESS TOOLS Users can access the file information through the American FactFinder on the U.S. Census Bureau’s Web site <www.census.gov>. Users can utilize their standard software packages to manipulate the data. The data are presented in both fixed-length ASCII and comma-separated ASCII formats, which can be easily imported into other software packages. A flat ASCII file is available for download via File Transfer Protocol (FTP) from American FactFinder. GEOGRAPHIC HIERARCHY PRIMER The smallest component for all census geography is the block. Figure 2-3 provides an example of the various geographic hierarchies used, building from the block. Take some time to review this chart to become familiar with the different hierarchies. Begin reading the schematic from the bottom at the blocks entry. By following the lines, you can see the hierarchy very quickly. For example, follow blocks to block groups to census tracts to counties. This path indicates that census tracts and their sublevels in the hierarchy are uniquely identified within a county and do not cross county boundaries. GEOGRAPHIC HEADER RECORD The geographic header record, Figure 2-4 at the end of this chapter, defines each field and provides its data dictionary reference name, field size, starting position, and data type. In addition, the presence or absence of an “X” in each summary level column is a guide to the presence or absence of geographic information for that particular summary level. For example, on the column for summary level 040, we see “X” for the first 10 fields, indicating that there will be information for those fields. In the county field, there is no “X,” indicating that there is no information for county in summary level 040. Since 040 is the summary level for state, this is perfectly logical.
