Census Summary Form 2 (SF2)
//////////////////////////
What is SF2?

   Summary File 2 (SF 2) contains the data compiled from the questions asked of 
   all people and about every housing unit. SF 2 includes population characteristics,
   such as sex, age, average household size, household type, and relationship to 
   householder such as nonrelative or child. The file includes housing characteristics,
   such as tenure (whether a housing unit is owner-occupied or renter-occupied), 
   age of householder, and household size for occupied housing units. 

  Selected aggregates and medians also are provided. A complete listing of 
  subjects in SF 2 is found in Chapter 3, Subject Locator. The layout of the 
  tables in SF 2 is similar to those in SF 1. 

  These data are presented in 47 population tables (identified with a "PCT") 
  and 14 housing tables (identified with an "HCT") shown down to the census 
  tract level; and 10 population tables (identified with a "PCO") shown 
  down to the county level, for a total of 71 tables. Each table is iterated 
  for 331 population groups: the total population, 75 race categories, 114 
  American Indian and Alaska Native categories (reflecting 60 tribal groupings), 
  47 Asian categories (reflecting 24 Asian groups), 43 Native Hawaiian and Other 
  Pacific Islander categories (reflecting 22 Native Hawaiian and Other Pacific
  Islander groups) and 51 Hispanic/not Hispanic groups. The presentation of SF 2 
  tables for any of the 331 population groups is subject to a population threshold 
  of 100 or more people. That is, if there are 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 in SF 2.
