==== The history of SES coding for CATSLife subjects ====

  * Bluebooks (see page S-25) filled out by the CAP biological, adoptive, and control parents when children entered the project included questions about present occupations, highest-ranking occupation (past & present) & longest-held occupation.  These occupations were originally scored using the **Hawaii NORC** scaling used in the Hawaii Family Study of Cognitiion.
  * TIP parents filled out a similar set of questions when their children entered the project.
  * LTS-only parents filled out a demographic survey at 14 months that was scored using the **New NORC**
  * When CAP s LTS subjects reached age 16, any occupations listed in their versions of the Bluebooks were coded using the **New NORC**
  * Scoring at later ages used the **Newer NORC** scoring

==== A history of the sequential development of the Prestige and SEI (status,education,income) scores. ====

{{:catslife:documents:gss_codebook_appendixg.pdf|NORC scoring}} presents an overview of SES coding through the General Social Survey (GSS) of 1989. The GSS is conducted by the National Opinion Research Center (NORC) at the University of Chicago.

  * The oldest NORC that has been used in CAP was based on occupational titles from the 1950 census and referenced in Reiss (1961).
  * The **Old NORC** was the one developed from 1960 census codes. Codebook used by Denise Daniels to score Old Norc, Old SEI, Hawaii NORC, New NORC and New SEI is found here: {{:catslife:documents:integrated_ses_titles.pdf| Job title index to six SES measures}}
  * The **Hawaii NORC** was an adaptation of this used for the Hawaii Family Study of Cognition
  * The **New NORC** was the scoring from the 1970 census by Siegel and described in the Hauser & Featherman (1977) book. {{:catslife:documents:newnorc.docx| Coding for New NORC}}
  * The **Newer NORC** was the scoring from the 1980 census codes by Keiko & Treas (1989). {{:catslife:documents:newernorc.pdf| Coding for Newer NORC}}
  * The **Newest NORC** was developed from 2010 census codes (used for SES scoring in COMN project). {{ :catslife:documents:prestg10sei10_supplement.xls |Coding for 2010 census codes}}
