## The SIPP: The Evolution of a PhoenixDavid Johnson

## The SIPP Evolution

## Dear President Bush

- March 10, 2006

## The Save the SIPP Campaign

- New York Times Editorials
- Discovering What Happens Next
- Save our SIPP
- The Continuing Saga of SIPP
- NY Representative, Carolyn Maloney stated:
**I want to thank all of the policy groups and economists who worked so hard to help reverse the Administration’s original SIPP decision.  Because of their dedication and hard work, the Administration came to understand how important SIPP is to creating and implementing good public policy.” **

## The Unique Value of SIPP

**To provide a nationally representative sample for evaluating:**
**annual and sub-annual dynamics of income**
**movements into and out of government transfer programs**
**family and social context of individuals and households**
**interactions between these items**

## Census reports in the Media

## Current Uses of SIPP (recent CBO reports)

## SIPP 2008 Panel Highlights

- Target of 45,000 Household sample
- Wave 1 begins in Sept 2008
- Modified 2004 Panel TM structure
- Same Wave 1, 2.  Wave 3 TMs on Wave 4, etc.
- Collection for 3-4 years
- State representativeness and reliability for 20 states
- Waves released 9 months after data collection completed

## Our work on SIPP Improvements 

- Improve Processing System and Collection Instrument
- Develop Event History Calendar (EHC)  Instrument
- Examine use of administrative records data to supplement and evaluate survey data
- Continue meetings with stakeholders, development of survey content, and use of reimbursable supplements

## Improving Processing System

- Convert CAPI instrument to BLAISE
- Develop processing system in conjunction with survey instrument for reengineered SIPP
- Document processing system
- Convert from FORTRAN to SAS
- Document edit and imputation procedures

## Evaluate use of EHC

-  An EHC interview is centered around a customized calendar that shows the reference period under investigation
- The calendar contains timelines for different domains
- Landmark events, such as holidays and birthdays can be used to aid the respondent’s memory
- Many surveys using EHC – PSID, LAFANS, ELSA

## 2008 Paper Test 

**Paper instrument (Control card, EHC, and Assets Questions)**
**Administered April/May 2008**
**A reinterview evaluation and validation test**
**Reinterview of 2004 panel SIPP respondents to recollect information for calendar year 2007 (about 2000 households)**
**Cases completing Wave 12 of SIPP 2004 Panel (Primed)**
**Sample reduction cases cut after Wave 8 2004 Panel (Un-Primed)**
**Pairwise comparison of responses from the two data sources**
**Validation of responses using administrative records matched at the individual level; assess the occurrence, timing, and distributional differences.**
**Interviewer debriefings and qualitative analyses to refine concepts and training procedures **

## Use of Administrative Records 

- National-level data
- SIPP linked with administrative records data at the person level
- Examining imputation methods
- Creation of SIPP Synthetic Beta File matched with SSA data
- State-level data
- Many social programs administered at the state-level
- SIPP data linked to social program data from  states, e.g., Texas, Illinois
