IFLS collaborators: IFLS1 was a collaborative effort of RAND and Lembaga Demografi of the University of Indonesia. IFLS2 was a collaborative effort of RAND, UCLA, and Lembaga Demografi of the University of Indonesia. IFLS3 was a collaborative effort of RAND and the Center for Population and Policy Studies (CPPS) of the University of Gadjah Mada. IFLS4 was conducted by RAND, the center for Population and Policy Studies (CPPS) of the University of Gadjah Mada and Survey Meter. IFLS5 is a collaboration between RAND and Survey Meter. IFLS1 is copyrighted by RAND and Lembaga Demografi. IFLS2 is copyrighted by RAND.

Please do not distribute these data. The data are freely available on our website. It is useful for everyone if we maintain a list of all users. If you plan to work with other people using these data, please ask them to register or register them yourself. If you are a data librarian, please ask users to register on our web page if they obtain a copy of the data from you.

The IFLS data are placed in the public domain to support research analyses. As a user of the IFLS public use files, you are expected to respect the anonymity of all our respondents. This means that you will make no attempt to identify any individual, household, family, service provider or community other than in terms of the anonymous codes used in the IFLS.

Data and Documentation formats

Data formats

IFLS data are available in the following formats:

IFLS1-RR and IFLS2:

IFLS3:

  • SAS 8.2 export
  • Stata 7.0

IFLS4:

  • SAS 9 export (xport engine)
  • Stata 9

IFLS5:

  • SAS 9 transport (cport/cimport)
  • Stata 9

SAS users should click here for information on how the export format data files were created.

Documentation formats

Electronic documentation is available as Adobe Acrobat pdf files; codebooks are available both as pdf files and machine readable text files. The .cbk extension used in IFLS2 and IFLS3 does not define a file type—it merely identifies the text file as being in a codebook text file.

When printing a PDF document, click "shrink to fit"; this is particularly important when printing questionnaires which were formatted for A4 paper.

IFLS1-RR documentation is available in hardcopy from RAND Distribution Services. They may be contacted by phone at 310-393-0411, Ext. 6686; by fax at 310-451-6915 or by e-mail at order@rand.org. IFLS2, IFLS3 and IFLS4 documentation is only available on this web page.

Using this site

Click on the files that you would like to download.

Because many of the files are large, we have posted them in two ways:

  • single zip files containing all sub files
  • separate zip files each containing a subset of files

Users who have difficulty maintaining a connection to the site for an extended period may wish to get the separate files. If your web browser is set so that data are automatically uncompressed once transfered to your machine, turn that option off. Click here for information on zip.

IFLS1 DATA AND DOCUMENTATION

The original IFLS1 data have been replaced by a re-release, IFLS1-RR. It is intended to facilitate using IFLS1 and IFLS2 in combination. We encourage users to use IFLS1-RR since it incorporates adjustments outlined in the fixes files, joins subfiles having the same unit of observation, and adds identifiers that make it easier to link IFLS1 and IFLS2 data. Those users of the original IFLS1 data who wish to continue using the original IFLS1 data with IFLS2 should read Section 6 of Volume 2 of the IFLS2 documentation (see below).

Crosswalks between IFLS1 and IFLS2 facility and community codes are available below under "Notes for IFLS1-Original users." See IFLS1-RR data updates for a note about how the auxiliary file expend2, containing household expenditure estimates, was created.

Note: In RAND publication #DRU-1195/7, "Documentation for IFLS1-RR: Revised and Restructured 1993 Indonesian Family Life Survey Data, Wave I" by Christine E. Peterson, there are references to two files not listed in the table below: COMMID93 and FACXWALK. Information on these files can be found in a later section of this page, "Notes for IFLS1-original users."

IFLS2 DATA AND DOCUMENTATION

An updated version of the IFLS2 data is now available for research purposes. The updated data now includes the following previously unreleased modules: migration (MG), labor force participation (TK), contraceptive calendar (KL), cognitive tests (EK) and physical health assessments (US).

Note that the Book 3 and Book 4 zip files for SAS export and Stata files have been updated below as has the hh97dta.zip and hh97xpt.zip files. There are no ascii versions for the MG, TK, KL, EK and US modules. Also, there are no codebooks for these new modules. The Book 3 and Book 4 codebooks have not been updated, nor have book US or Book EK codebooks been generated. The MG, TK, KL, EK and US modules have variable formats in the Stata file versions. SAS users will have to use the questionnaires for code definitions in those new data files. The EK cognitive test questions are now available. The forms are in English with some graphics missing for ages 7-9 and 10-12, and are only in Indonesian for ages 13-15 and 16-24. The Indonesian EK test forms are scanned hard copies.

IFLS CONSUMPTION/EXPENDITURE AGGREGATES

Consumption/Expenditure aggregates are available for IFLS1-IFLS4. These files are provided as a courtesy and users can either use them or leave them. There is no support provided for these files.

The zip file includes both the data and the Stata programs that created the data. The IFLS4 data does not have deflators as yet, so the aggregates for 2007 are only in nominal terms. Deflators for 1993 are under the Updates page below. The zip file includes deflators for IFLS2 (1997) and IFLS3 (2000). Please read the PDF documentation describing the consumption/aggregate data for details on all the files in the zip file.

NOTES FOR IFLS1-Original users

If you are using the original IFLS1 data, you will need the following files to use those data in combination with IFLS2.

See Section 6, Volume 2 of the IFLS2 documentation.

DATA UPDATES, USAGE NOTES and TIPS

Information on data updates, answers to frequently asked questions, tips and usage notes are available here. These notes include SAS and STATA programming code to help you use the IFLS data.

Major data revisions will be announced by email to all registered users. If you wish to unregister, send email to ifls-supp@rand.org.

ZIP UTILITIES

To unzip the zip archives, you'll need a pkzip/pkunzip routine. Most data conversion routines can handle these files. This includes zip (in unix) and WinZip (on Windows). Some zip files are an archive of zip files; you will need to use unzip twice on those files.
