Changes in Existing Variables:

Several variables were updated to account for the passage of time, that is, the highest value is now '2001' rather than '1999'; these include:
     BUILT (year built)
     WHNGET (year unit acquired)
     MOVE (year moved to unit)
     and probably some variables in the mortgage module
Several continuous variables were updated to allow larger entries, these were changed from an allowable 6-digit field to an allowable 7-digit field; due to topcoding there may be no 7-digit responses on the PUF but it is now possible to collect such figures; these variables include:
     AMMORT (amount borrowed by primary mortgage)
     RESMOR (amount of primary mortgage applying only to home)
     AMTM (amount other charges part of primary mortgage payment)
     AMMRT2 (amount borrowed by secondary mortgage)
     RESMR2 (amount of secondary mortgge applying only to home)
     AMTM2 (amount other charges part of secondary mortgge payment)
     AMMRT3 (amount borrow by third mortgage)
     AMMRT4 (amount borrow by fourth and remaining mortgages)
     VALUE (value of unit and lot)
     LPRICE (purchase price)
     CPRICE (construction cost)
     LVALUE (value of land -- manufactured housing on owned land only)
     PVALUE (value of entire property -- non-specified units)
     SAL (wage and salary income)
     VOTHER (amount of non-wage income)
     ZINC (family income)
     ZINC2 (household income)
     ZINCN (expected income in next 12 months)
     and probably some variables in the mortgage module
The variable NUNIT2 (structure type) has been collapsed to 4 categories. Categories 4 (1-unit manufactured home) and 5 (unit in multiunit manufactured home) were combined. The codes for 2001 are:
     1 = 1 unit, detached
     2 = 1 unit, attached
     3 = unit in multiunit structure
     4 = manufactured (mobile) home
The variable OTHFN (number of other finished rooms) has increased the maximum allowable entry from 5 to 10.
The variable SCHHO was created to provide a new answer category for the question 'Does . . . attend a public school or a private school?' The answer codes are:
     X = schooled at home
     B = non-applicable
     missing is allowable
The SCHNO variable now means 'not in school'; in previous years either answer would have been coded to SCHNO.
