Census of Population and Housing, 2000 [United States]: Summary File 2, Alabama (ICPSR 13233)
Published: May 24, 2013
Summary File 2 contains 100-percent United States decennial Census data, which is the information compiled from the questions asked of all people and about every housing unit. Population items include sex, age, race, Hispanic or Latino origin, household relationship, and group quarters occupancy. Housing items include occupancy status, vacancy status, and tenure (owner occupied or renter occupied). The 100-percent data are presented in 36 population tables ("PCT") and 11 housing tables ("HCT") down to the census tract level. Each table is iterated for 250 population groups: the total population, 132 race groups, 78 American Indian and Alaska Native tribe categories (reflecting 39 individual tribes), and 39 Hispanic or Latino groups. The presentation of tables for any of the 250 population groups is subject to a population threshold of 100 or more people. That is, if there were fewer than 100 people in a specific population group in a specific geographic area, their population and housing characteristics data are not available for that geographic area.

Data Collection Notes
Because of the number of files per state in Summary File 2, ICPSR has given each state its own ICPSR study number in the range ICPSR 13233-13284.
The data are provided in four segments (files) per iteration. These segments are PCT1-PCT4, PCT5-PCT19, PCT20-PCT36, and HCT1-HCT11. The iterations are Parts 1-250, the Geographic Header file is Part 251. The Geographic Header file is in fixed-format ASCII and the Table files are in comma-delimited ASCII format. The Geographic Header file has 83 variables, Segment 01 has 224 variables, Segment 02 has 241 variables, Segment 03 has 179 variables, and Segment 04 has 141 variables. When all the segments are merged, there are 849 variables.
