IFLS Data and Documentation

Thank you for registering with the IFLS. Links to downloading the data are on this webpage. When necessary, we will send emails regarding updates and other announcements. If your email address has changed, please re-register to update your details with us.

It is helpful for us to be able to document usage of IFLS. Funding of future waves of the IFLS will depend on demonstrating the data are of value to the research and policy making community. We ask, therefore, that you please email a link to any papers that you publish using the IFLS data to ifls-papers@rand.org.

Your paper will be included in the bibliography of IFLS papers.

To assist us in tracking usage, it would be helpful if you use the following citations in papers that use IFLS:

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 Support

User data support for IFLS will be limited in the future, and response times for questions emailed to ifls-supp@rand.org may be longer than previously.

Before contacting us, please review all IFLS documentation for all waves, as most questions can be answered by reviewing the User’s Guides, questionnaires, and the Data Updates, Tips and FAQs web page. As some information is not carried along from wave to wave in the User’s Guide and changes do occur in the questionnaires across waves, users must look at the documentation for all waves when trying to answer a question. Users should also dump data records and look at the actual structure of the data file. Simply looking at frequencies will not always explain what the data looks like.

Questions related to working with IFLS data must include the wave(s) you are working with along with the specific data files and variables being used. We cannot provide programming support nor provide guidance on what statistical models might be used or how to run such models.

Data and Documentation Formats

Data Formats

IFLS data are available in the following formats:

IFLS1-RR and IFLS2:

• SAS 6 export,
• STATA 6, and
• ASCII

IFLS3:

• SAS 8.2 export
• Stata 7.0

IFLS4:

• SAS 9 export (xport engine)
• Stata 9

IFLS5:

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

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.

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.

READ FIRST: Important Note Regarding IFLS Data

IFLS users must read the User’s Guides (both volumes) and review the questionnaires before working with the data due to the complexity of the IFLS. Most questions users will have will be answered by reviewing those documents. Because not all information is repeated from wave to wave in the user’s guides, users should read the guides and documentation from earlier waves, especially if one is looking to exploit the longitudinal nature of the IFLS. Generally, even if one is only focusing on one wave (e.g., IFLS5), one still needs to pull data from earlier IFLS waves since full event histories are not repeated wave to wave.

Users should also look through the IFLS Data Updates, Data Notes, Tips and FAQs section before working with the data as questions that arise may already be answered in that section.

It is important for IFLS users to remember that IFLS files can have different units of observation (e.g., some are per household, some per individual, some per event) and some will have multiple records per unit of observation (e.g., multiple records for the mother in the Book 4 birth history). The User’s Guide appendices contain tables that show the unit of observation and the requisite record identification variables to help users understand what may be needed to merge files with differing units of observation together. In some cases, users may need to collapse multiple records per respondent to one record per respondent, for example, before merging on other data that is one record per respondent.

Users should look at the IFLS2 User’s Guide as it talks about family relationships and how to identify spouses, children, and parents across modules. That information holds for all IFLS waves. Also, chapters 4, 5 and 6 of the IFLS1 User’s Guide may be of interest as well since they talk about identifying and linking data among related individuals.

Also, users must remember that the IFLS utilizes many skip patterns and it is therefore crucial that users examine the IFLS questionnaires for the variables with which they are working to understand how a question is asked and who answers it. If one sees a variable with lots of blank values, it means that the variable is involved in a skip pattern and a large number of respondents did not meet the criteria to be asked that given question. It does not mean there is missing data. If a respondent said “I don’t know” or refused to answer or should have answered but did not, there is a missing value code to indicate those situations.

IFLS1 Data and Documentation

Please read the IFLS1 document (DRU-1195/7) called "Documentation for IFLS1-RR: Revised and Restructured 1993 Indonesian Family Life Survey Data, Wave 1". It explains how the IFLS1-RR data, which is the version that is on the IFLS data download site, varies from the structure of the original IFLS1 release data. One of things we did was to combine files with the same unit of observation so there are fewer files in IFLS1-RR than in the original release and DRU-1195/7 shows you which files were combined into a single new file. However, due to limited funding, we did not redo the codebooks. As explained in the above document (DRU-1195/7), the codebooks are still useful for explaining the code values of variables even though the file structure in IFLS1-RR is different. One must use both the codebook and the IFLS1-RR document together to understand the data structure and contents.

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, mentioned above, 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."

Please check the IFLS1-RR updates and data notes section for updates to the data since initial release and for notes of interest about IFLS1-RR data content.

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.

Please check the IFLS2 updates and data notes section for updates to the data since initial release and for notes of interest about IFLS2 data content.

IFLS Consumption/Expenditure Aggregates

Consumption/Expenditure aggregates are available ONLY for IFLS1-IFLS4. The Per Capita Expenditure (PCE) files covering IFLS1-IFLS4 were provided as a courtesy from a user. The files were not created by RAND and are not supported by RAND and RAND is not responsible for any issues with their content.

The zip file includes the data and the Stata programs that created the data plus PDF documentation describing the data. The data include deflators for IFLS2 and IFLS3 only, thus IFLS1 and IFLS4 data have only nominal values for their aggregates.

There are no PCE files for IFLS5 and no known plans to create ones. However, the user did provide the Stata code that created the IFLS4 PCE data (which is in the zip file with the existing PCE data). One would need to modify that code for IFLS5, as there may be some variable name changes (e.g., something collected in one variable is now collected in two or vice versa) and there may be new bracket variables to consider. One will have to cross-check the variables and files used in the IFLS4 program with the IFLS5 data to identify any differences that would need to be addressed.

Again, there are no deflators in the data for IFLS1 or IFLS4, and there are no deflators for IFLS5 should users choose to create PCE variables using IFLS5 data. Deflators for 1993 are under the Updates page below and there is a short discussion about deflators for IFLS4 and IFLS5 there as well.
