The Bureau of the Census has released Census 2000 Summary File 1 (SF1) 100-Percent data. The file includes the
following population items: sex, age, race, Hispanic or Latino origin, household relationship, and household and family
characteristics. Housing items include occupancy status and tenure (whether the unit is owner or renter occupied). SF1
does not include information on incomes, poverty status, overcrowded housing or age of housing. These topics will
be covered in Summary File 3. Data are available for states, counties, county subdivisions, places, census tracts, block
groups, and, where applicable, American Indian and Alaskan Native Areas and Hawaiian Home Lands.
The SF1 data are available on the Bureau's web site and may be retrieved from American FactFinder as tables, lists,
or maps. Users may also download a set of compressed ASCII files for each state via the Bureau's FTP server. There are
over 8000 data items available for each geographic area. The full listing of these data items is available here as a
downloadable compressed data base file named TABLES.ZIP.
The uncompressed is in FoxPro data base file (dbf) format and may be imported to ACCESS, EXCEL, and other software formats.
While all of this information is useful, the Office of Community Planning and Development has downloaded selected information
for all states and areas and is making this information available on the CPD web pages. The tables and data items selected are
those items used in the CDBG and HOME allocation formulas plus topics most pertinent
to the Comprehensive Housing Affordability Strategy (CHAS), the Consolidated Plan,
and similar overall economic and community development plans.
The information is contained in five compressed (zipped) dbf tables for each state. When uncompressed the tables are
ready for use with FoxPro and they can be imported into ACCESS, EXCEL, and other spreadsheet, GIS and database software.
The data are at the block group summary level. The first two characters of the file name are the state abbreviation.
The next two letters are BG for block group. Each record is labeled with the code and name of the city and county in which
it is located so that the data can be summarized to higher-level geography. The last part of the file name describes the contents
. The GEO file contains standard Census Bureau geographic identifiers for each block group, such as the metropolitan area code
and congressional district code. The only data included in this table is total population and total housing units. POP1 and POP2
contain selected population variables and selected housing items are in the HU file. The MA05 table data is only for use by State
CDBG grantees for the reporting of the racial composition of beneficiaries of Area Benefit activities.
The complete package for a state consists of the dictionary file named TABLES, and the five data files for the state.
The logical record number (LOGRECNO) links the records across tables.
