The California Work Pays Demonstration Project (CWPDP) was intended to assess the effects of recent changes in Aid to Families With Dependent Children (AFDC) provisions. The project documents the dynamics of family poverty and welfare use in California. Part 1, Overview Data: Cases contains one record for each CWPDP case sampled between October 1992 and March 1997. For each case, seven data presence indicator variables identify the presence of data in each of the data file types. Four observation variables identify the number of case-months records observed in the Four County Cases file, the number of person records observed in the Four County Persons and Assistance History Persons files, and the first month during which AFDC participation is observed in the Assistance History Persons file. Fifteen survey detail variables identify survey participation, interview completion, respondent's person number and date of birth, and the survey record number. Parts 2-5, Four County Data: Cases, contain case-month records for all control and experimental cases selected to be a part of the study between October 1992 and March 1997 for any month (beginning with the month selected) during which an assistance unit received AFDC of food stamps. Each case-month record contains county administrative data for eligible family size and type, income, and cash and food stamp assistance amounts. These files are identical to the Four County Data: Cases files in County Welfare Administrative Data Version 4. Parts 6-9, Four County Data: Persons, contain records for each person observed associated with any control or experimental case selected to be part of the study between October 1992 and March 1997. Records include nonconfidential demographic information and monthly values for aid type and eligibility. These files are identical to the Four County Data: Persons files in County Welfare Administrative Data Version 4. Parts 10-13, Assistance History Data: Aggregate, contain case-month records that summarize information for the months of January 1987 through December 1996 about the public assistance program participation and eligibility of persons associated with sampled cases. This dataset was constructed from the Assistance History Data: Persons datasets (Parts 14-17) that contain persons associated with the study units. Parts 14-17, Assistance History Data: Persons, contain the Medi-Cal and program participation history of each person associated with the assistance units for cases selected between October 1992 and March 1997. This dataset does not include information about persons who left the assistance unit before the month sampled. Each record includes program participation information for each month from January 1987 through December 1996, a total of 120 months, as well as demographic information. Parts 18-21, Medi-Cal Payments Data: Cases, contain one record for each case selected to be part of the CWPDP sample between December 1992 and March 1997. This dataset contains the Medi-Cal payments made for each case in the study for the month of December 1992 and quarterly from 1993 through the fourth quarter of 1997. University of California Data Archive and Technical Assistance receives this data from California Department of Social Services-Research Branch (CDSS-RB) by quarter (not month), aggregated to case number. Therefore, the data in these files are aggregated payments information for all assistance units with the same case number, whether or not that assistance unit is part of the CWPDP sample. These files are identical to the Medi-Cal Payments Data: Cases files in County Welfare Administrative Data Version 3.

(1) Administrative data, such as the files represented here, must be viewed in light of the original reasons for which the data were collected, as well as the original data systems used to collect and store the data. These data were collected for the purpose of administering a state assistance program. Without some understanding of the context of Welfare programs in California, users of these data may have difficulty conducting contextually meaningful analysis. Because of the interrelated nature of the files represented here, users are strongly advised to examine carefully the entire set of available files before beginning analysis. (2) The principal investigator delivered this data with the following note about the current version: This Version 4.1 of the County Welfare Administrative Data replaces all previous versions. The files in Version 4.1 correct a coding error in both the Version 4 Assistance History Data: Aggregate files and the Version 4 Assistance History Data: Persons files. Variables in the Overview Data: Cases files that relate to these two sets of data were also changed to reflect the corrections made to the Assistance History Data files. Also note that the files in Version 4 cover a longer data period than in Version 3. Four County Data files now contain 12 additional months of data through September 1998. Assistance History Data files contain two additional years of data.

Cases were sampled from the administrative welfare records sent by each county to University of California Data Archive and Technical Assistance.

For original sample cases, the weight was based on the sampling interval. The weight variable for additional sample cases was modified to account for undersampling of new sample cases due to the delayed entry of cases into the Medi-Cal Eligibility Data System (and, therefore, into the sampling pool). In Version 4, two weights were included for each case: the Sampling Interval Weight and the County Caseload Weight. The Sampling Interval Weight is the original weight implied by the sampling method. The County Caseload Weight is the weight needed to expand the original sample to the December 1992 caseload (for county-aid code cells) and to expand the additional samples to the number of new approvals (for county-aid code cells) during the sample month. Using state administrative data, County Caseload Weights were calculated by the principal investigator staff to reflect the number of AFDC cases a sample case represents. Expanding the original sample cases by using the County Caseload Weights, more accurately reflects the caseloads of the counties during December 1992. Similarly, expanding the additional sample cases by using the County Caseload Weights, more accurately reflects the number of new cases in the counties during the month selected for sample. After December 1992, it is not possible to weight up samples to determine county caseloads since certain types of cases were excluded from sampling. Additional sample cases can only be expanded to the number of cases new to welfare during the study period.
