CHANGE NOTICE #9 - 7/3/97

Change Notice #9 - 7/97 replacement data and documentation for 3/97 release of Wave 1 (1957-77) WLS Respondent and Sibling Data.

• Minor correction to 1957-77 data. Problem discovered by researcher using SPSS/PC 7.5 for Windows.

  ---

  Odd characters were written to locations which should have been blank for nine cases in the March 1997 update of Wave I data. This caused SPSS/PC 7.5 for windows to drop each of the nine cases following these with the "odd" characters. Unix and VMS versions of both SAS and SPSS still processed the data correctly; and SAS/PC 6.2 for windows processed the data correctly.

  Updated Wave I data with the odd characters restored to blanks is now available to download in dat23u3.tar.Z and dat23u3.exe

• Minor correction to the codebook only for variables for size of place (SPL100 and XSPL100).

  NOTE:     This code has been truncated to hundreds.  Ie. code "0"
  
            is for places from 1-99 in size, code "1" is for 100-199, etc.
