Data Sources

Administrative data for the CSDE project have come from the State of Wisconsin Department of Workforce Development. Data were extracted from four different databases:

Client Assistance for Re-employment and Economic Support (CARES)
Histories of AFDC, W-2, Food Stamp, Child Care, and Medical Assistance eligibility, participation, and level of use, from 1995 to 2000, were extracted from the CARES data system. Demographic information was also collected on resident parents and their children.

Kids Information Data System (KIDS)
The histories of child support awards, payments, distributions, and receipts were extracted from the KIDS database. Demographic information was also collected on nonresident parents and their children who were covered under the W-2 program. In addition, KIDS provides information on the establishment of paternity.

Computerized Reporting Network (CRN)
AFDC and Food Stamp histories prior to 1995 were extracted from the CRN database. (CRN was the public assistance database in use prior to the inauguration of CARES in 1995.)

Unemployment Insurance (UI)
Employment and wage histories of both resident and nonresident parents (1995-2000) were extracted from the quarterly wage record files of the UI program.

A User's Guide to the Administrative Data is available as a .pdf file. You will need Adobe Acrobat Reader in your computer to open this file.

Note:
"Nonresident" and "noncustodial" tend to be used interchangeably in the databases. "Noncustodial" is more strictly reserved for legal status as a child support obligor; CSDE has in general preferred to use the term "nonresidental" in describing the parent who does not live with the child.

Sample Selection

IRP staff extracted records from State administrative data sources each quarter, approximately two weeks after the end of the quarter. Selection of families studied in the CSDE project began with the identification of W-2 participants within the CARES database. These cases were opened during the 10-month period September 1997 to July 1998. The case participants were resident parents and their minor children. The minor children in these W-2 cases were traced in the KIDS data system, and their legal noncustodial parents, if any, were identified. Child support orders to noncustodial parents were identified in KIDS. Child support payments made by noncustodial parents and payments received by custodial parents were tracked through KIDS. The use of various forms of public assistance by W-2 resident parents was identified in CARES and CRN. Employment and wage histories were extracted on a quarterly basis for both resident and nonresident parents from the UI wage record database.

CSDE Administrative Data Files for Public Use

Data available in the public use files consist of a 75% random sample of CARES cases selected in the July 2000 extract. Public Use administrative data are provided in 12 separate data files that can be merged using a masked CARES case identifier. The data files are organized in the following way:


Master data files

Variables in master data files are extracted from all four data sources mentioned above: CARES, KIDS, CRN, and UI.

Resident-parent master file (demographic and summary variables) This data file contains one record per W-2 participant/resident parent. A number of demographic variables are included, as well as a number of summary variables which describe, in aggregate, the children in the family, the number of nonresident parents associated with the family, and the employment and earnings history of the resident parent. The unit of observation is the W-2 CARES case.

Nonresident parent master file (demographic and summary variables)
This data file contains one record per nonresident/resident parent pair. Note that more than one nonresident parent may be associated with one resident parent. Also, if a parent is a nonresident parent in more than one W-2 family, then this nonresident parent would appear multiple times in this master data file. If there is no identified, legally responsible nonresident parent in a family, then no observations in this master data file will be associated with this W-2 case. The nonresident master file contains information on demographic characteristics and summary employment and wage histories of nonresident parents. The unit of observation is the nonresident parent per CARES case.

Auxiliary data files from KIDS

The unit of observation for all auxiliary files is month, per KIDS account, per CARES case.

Child Support Owed
This file contains monthly dollar amounts of child support owed by the noncustodial parent to the custodial parent.

Child Support Paid
This file contains monthly dollar amounts of child support paid by the noncustodial parent to the custodial parent's account.

Child Support Retained
This file contains monthly dollar amounts of child support retained by the state from the custodial parent's account.

Child Support Received
This file contains monthly dollar amounts of child support received by the custodial parent.

Auxilliary data files from CARES

W-2 Slot History
This file contains monthly information on the slot assignment of the W-2 participant. The slot assignment determines the kinds of services provided to the resident parent, and whether or not the parent receives a monthly monetary grant. Resident parents who receive a monetary grant are subject to the partial pass-through of child support if they are a Control case. The unit of observation is month, per CARES case.

W-2 Grant Payments
This file contains monthly dollar amounts of W-2 grant payments. The unit of observation is month, per CARES case.

Food Stamp Benefits
This file contains monthly dollar amounts of Food Stamp benefits received by the W-2 resident parent and children.

Child Care Benefits
This file contains monthly dollar amounts of child care benefits associated with the W-2 case. The dollar amount given is that sent to the child care provider, not to the W-2 participant.

Medical Assistance
This file contains the monthly Medicaid eligibility of the W-2 participant, and the capitation rate for Medicaid recipients in that county for that month.

BadgerCare Medical Assistance
This file contains the monthly BadgerCare eligibility of the W-2 participant who exits W-2 and Medicaid. The dollar amount is the capitation rate for BadgerCare recipients in that county for that month. (BadgerCare is a Wisconsin medical assistance program that began in July 1999 for low-income individuals who are not eligible for Medicaid.)
