V2005: SCRAMBLED CONTROL NUMBER
Notes: Beginning with the quarter 1, 2006 NCVS PUF, census used the 2000 sample design control number scrambling routine to scramble control numbers for 1990 and 2000 sample design cases. Therefore, data users will not be able to match 1990 sample design cases on NCVS PUFs released in quarter 1, 2006 and beyond to 1990 sample design cases on NCVS PUFs released prior to quarter 1, 2006. Beginning in July 1986 the previously used PSU, segment number, check digit and serial number are scrambled together by the Census Bureau as one variable to preserve confidentiality. For 1980 sample-first 10 digits -- last four digits are blank (through Quarter 4, 1995). For 1990 sample-all 14 digits are used (beginning Quarter 3, 1995). Scrambled control number (part) - See V2007 for last two digits of scrambled control number.
Based upon 170,628 valid cases out of 170,628 total cases.
