Newsweek: The Benefits of Busy: A new study finds that 'overscheduling' is a myth.

Release of a new and improved PSID - CDS Data Center.

Two exciting new capabilities include a Cross-Year Variable Index allowing searching across all 48,000 variables and 34 waves of PSID data and 2 waves of Child Development Supplement data. Searches may be conducted by Topical Domain, by Year, by File, and by Archived Data Carts. During these searches, codebook information may be simultaneously accessed, and data downloaded into a data cart with a click of the mouse. http://simba.isr.umich.edu

In addition, a new software tool has been developed to facilitate the creation of data extracts for generational research. These extracts make it easier to link PSID and/or CDS data on a target individual to the PSID and/or CDS data on their parents, grandparents, and siblings across all waves.
This tool is called the Family Identification and Mapping System (FIMS) and may be accessed here: http://simba.isr.umich.edu/FIMS

PSID is now requiring users to register prior to downloading data in order to impart our Conditions of Use. Registration is very easy, and is required only once. Once registered, return trips can be made using a login and password.

Release 4 contains corrections to the father's IDs for two records.

2003 Family History Files have been released. These three files - Marriage History File: 1985-2003, Childbirth and Adoption History File: 1985-2003, and Parent Identification File: 2003 can be downloaded as ZIP packages from the Supplemental Data page.

"U.S. children and teens spend more time on academics" press release by Juster, Stafford, and Ono highlight time use data from the Child Development Supplement. See http://www.umich.edu/news/index.html?Releases/2004/Nov04/r111704a for the full news story.

The data, publicly available since August 13, 2004, is available at the Data Center. We expect to post the files used in the News note in the future, after some additional data checks.

The CDS-II data are now available through the PSID-CDS Data Center.

We have released the following files: PCG Child, PCG Household, OCG Child, OCG Household, Child Interview, Assessments, Teacher Interview, and Demographic file, based on data collected on 2,907 CDS children/youth aged 5-18 in the fall of 2002/ spring of 2003. These same children were interviewed in 1997 when they were 0-12 for CDS-I, also available through the PSID-CDS Data Center. Each data file is accompanied by a complete on-line codebook. In the Data Center, a map of the caregiver"s PSID IDs now accompanies all CDS downloads. This map can be used to link PSID main study individual data about the caregivers with the CDS data. See the CDS web pages for questionnaires and other study documentation. A User Guide for CDS II will be available around Labor Day 2004; Time Diary data are planned for release in the early fall of 2004.

Various PSID/CDS funding agencies would be pleased to receive applications for secondary data analysis of the PSID/CDS.

The PSID and CDS bibliography Web pages have been upgraded.

• You may submit your own citation.
• You may search by author, title, year, or full citation.
• Browse citations by keyword or author.

We now have 3 online tutorials on using the PSID for multigenerational analysis. Try them out at the tutorials section of this site.

These are Tutorial #4 (extensively revised and matches the new Data Center's new intergenerational file features as of fall 2003), and now Tutorial #5A (home ownership) and Tutorial 5B (birthweight in CDS and health of the mother and grandmother).

We now have a tutorial highlighting the main features of the data center and how to use them. Check it out! (HTML) | (Powerpoint)

The PSID Web site documents are searchable.

The variable search interface has also been upgraded. You can now search for variables using variable name, label, question and explanation text form 1968-2001 core and most of the supplemental files, including CDS.

The PSID has upgraded its Web Site http://psidonline.isr.umich.edu and Data & Documentation Center: http://simba.isr.umich.edu/

The new Data & Documentation Center now contains all waves of PSID data 1968-2001 and Child Development (CDS-I) data along with full Codebooks for each wave of data. Features of the new Data & Documentation Center include:

• Automatic merging of multiple waves of PSID and PSID-CDS data with your choice of merging options
• Customized codebooks in PDF, HTML, XML, and more
• Easy to use data shopping cart system
• Save your data sets for sharing with others, or for updating and editing later
• Many optional output formats, including Excel, SAS, STATA, SPSS
• Search and Browse variables

This feature lets you create and download data from core PSID files on CDS1997 PCGs' and OCGs' and data-map that relates Child to (Primary Caregiver (PCG) and/or Other Caregiver (OCG)). This data-map is helpful in allowing CDS researchers to merge caregiver files with child files.

ICPSR Summer Courses in Quantitative Methods presents a 3 day workshop on "Using the PSID," June 2-4, 2003 in Ann Arbor, MI. Enrollment is limited. See this link for further details: http://www.icpsr.umich.edu/training/summer/courses/2003-03-27.html

Data Alert: If you created a dataset using the Data Center at any time between 1/27/2003 and 2/20/2003 with multiple years of family and individual level variables, please generate a new dataset. It is possible that your dataset was incorrectly merged by the Data Center during that time. We apologize for any inconvenience this may have caused. If you are a registered user and saved any Data Carts during this time period, you can now simply re-run them to generate a corrected dataset.

Data Center subsetting tutorial # 2 (with Excel option): Changes in Participation in the Food Stamp Program

Recently we have added dBase as an output option for Data Center files that can easily be imported into Microsoft Excel. Also, the subsetting capacity has been improved. We have made available a second tutorial, titled: Changes in Participation in the Food Stamp Program on how to use the Data Center to produce dBase files that can be read into an Excel file and then processed and analyzed in Excel. Now, we are making available such an example in the belief that Excel users can see from the spreadsheet the processing steps.

The Excel file was for 1999 [5232 observations*] and took 14 Data Center PRI [Excel columns A-N] (family and individual) variables (labeled on the spreadsheet) to calculate [Excel columns O-AK] weighted (normalizing the individual weight to 1.000 and excluding those cases with no individual weight) housework hours of men (heads) and women (wives plus female heads). Then average housework hours of married men and married women (and by number of children living in the family) were calculated [S5234-5235 - AK5234-5235].

By clicking on the cells one can see the logical and calculation steps used in Excel. This full tutorial became available by December of 2001.
