This appendix presents SAS programs for the creation of income and assets variables. Unless otherwise noted, the programs presented are for round 20. In cases where a variable has been discontinued, the program for the final round in which it was created is presented. Except for minor hand edits to account for inconsistencies in the raw data, variable creation code remains generally constant from round to round.

• Census Region of Residence at Survey Date
• MSA Status at Survey Date
• Rural vs. Urban
• Distance to Parents' Residence

Several variables in the main data set provide information about the respondent's area of residence.

This appendix presents SAS programs for the creation of variables related to the respondent's family background, household, marriage/cohabitation, and fertility.

However, users who need code for a specific round not included here may contact NLS User Services.

The main file NLSY97 data set contains a number of created variables. These created variables will be included on each public release of the NLSY97. With very few exceptions, these variables are either commonly used items that are derived from a number of different NLSY97 survey questions or longitudinal items that require updating in each round. If they were not provided, creating either the longitudinal or the cross-sectional variables might present difficulties for some NLSY97 users.
