Wave 1 differences from version 4.1 to 5.pdf

 

Changes were made to both the Wave 1 and Wave 2 datasets during the production of Wave 3. Wave 1 and Wave 2 cleaning of the data has been on-going since the previous release of the data. We paid special attention to key variables, such date of birth, gender, population group and highest education, as well as the birth history section and questions about parent vital status (are they alive or dead) in Wave 3. Where there was a discrepancy across waves we did callbacks to confirm what the correct answer is. Were we have learned that either Wave 1 or Wave 2 was incorrect we updated the data in those datasets to reflect the correct information. In some cases this has resulted in questionnaire type changes due to changes in dates of birth. In other cases we have had to update the CSM/TSM tag for new children as we learned either their real date of birth or where we learned that their mother was interviewed as a TSM in Wave 2.

During Wave 3 fieldwork we also learned about more cases were we had duplicate households from Wave 1 or where people were interviewed in more than one household and incorrectly presented as two separate records.

As a result there is a change in the number of individuals and households in Wave 1.

Changes to Wave 1 Data from version 5 to version 5.1.pdf

 

An Admin dataset has been included in the regular pack for Wave 1, instead of having it as a separate item to download. The result is that there is a new version of Wave 1 available. Other minor changes have been made as we corrected small issues brought to our attention since the previous release. This document outlines the specifics of the changes between Version 5.0 and Version 5.1.

In addition to the public release dataset, SALDRU also prepares an internal dataset that includes the full geo-coding, employment coding and PSU information. The Secure Datasets include text variables as they are captured in the questionnaire. Where possible, coded or aggregated information is released as part of the public release dataset, e.g. employment and sector codes to the one-digit level. This document gives the details of the additional variables in the Secure dataset.

This manual serves as a guide line for the field workers when they conduct interviews. In it, are basic guidelines per section of each questionnaire on what field workers need to be aware of as they ask the questions from the respondents? Some of the guidelines include protocols for the fieldworkers and the managers covering issues of professionalism, ethics, confidentiality and consent. In addition to the above, the manual also covers issues on sampling and respondent selection and how to find the sampled dwelling units.
