Welcome to the National Income Dynamics Study

NIDS, telling the stories of the people of South Africa.

The National Income Dynamics Study (NIDS) has been providing empirical data on the changing lives of South Africans since 2008. NIDS is an initiative of the Department of Planning, Monitoring and Evaluation (DPME) and is implemented by the Southern Africa Labour and Development Research Unit (SALDRU) at the University of Cape Town (UCT).

As the first national panel study of individuals in South Africa, NIDS provides unique insights into the lives of individual South Africans over time. To help people effectively use NIDS, NIDS provides example findings, scholarships, summary videos and training on how to use its panel data.

Announcements

New Dataset including Wave 4

A new release of the NIDS data is now available. This release addresses 2 main issues affecting the weights variables, w’x’_pweight in the indderived data file and the w`x’_wgt in the hhderived data file (`x’ is the wave number). The issues are as follows:

1.  Missing panel weights for some babies born to CSM mothers after Wave 1 (2008).

2.  One (now adult) respondent with a missing weight.

Other minor issues can be found in the change documentation.

We recommend that users who have downloaded the data on or after the 19th May 2016 (Wave1_V6.0, Wave2_V3.0, Wave3_V2.0 and Wave1_V6.0) and have made use of the w’x’_pweight and the w`x’_wgt variables, re-run their analysis.

NIDS in the Media

Star - School Performance linked to nutrition

School performance linked to nutritionAn article by Siphumelele Khumalo which was published in Star on 1 March, explains how research by Daniela Casale which used the NIDS data, revealed a link between child health and educational performance. Quoting Samantha Richmond, NIDS Senior Operations Manager, the article explains that the research found that children who were stunted were found to have enrolled later for Grade 1, completed fewer years of schooling and were more likely to have failed grades. Further, that this could ultimately impact on their earning potential later in life. Read the full article (available for Pressreader.com subscribers).

 

Business Day - The real state of the nation: How to solve long term problems

The real state of the nationIn a 20th of February Business Day article, Samantha Richmond, Senior Operations Manager at the National Income Dynamics Study (NIDS), discussed the state of South Africa. She revealed evidence on the lived realities of South Africans drawn from the NIDS data and outlined factors which should be considered in the new President’s eagerly awaited policy reforms. These factors emanate from analyses conducted by various experts using the data collected from 28,000 South Africans, and the people they live with, since 2008 in NIDS.

Training and Outreach

NIDS Hosts Year-End 3-day Panel Data Course

The 3-day NIDS Panel Data Course, which took place from 6 - 8 December at UCT’s School of Economics, provided an introduction to analysing the NIDS Wave 1-4 data using Stata. More specifically, the techniques used in the analysis of longitudinal household survey data (i.e. panel data) were explored. Accordingly, some of the topics covered over the 3 days included panel data management, transitions over time, weighting and differential attrition. The course was designed for people with prior experience using Stata to analyse cross-sectional household survey data and was attended by 22 economics researchers, lecturers, students and monitoring and evaluation practitioners from across South Africa. According to many of the attendees, the skills that they developed during the course will prove useful for their future research endeavours.
