Abstract
The National Income Dynamics Study (NIDS) is a face-to-face longitudinal survey of individuals living in South Africa as well as their households. The survey was designed to give effect to the dimensions of the well-being of South Africans, to be tracked over time. At the broadest level, these were:
Wealth creation in terms of income and expenditure dynamics and asset endowments;
Demographic dynamics as these relate to household composition and migration;
Social heritage, including education and employment dynamics, the impact of life events (including positive and negative shocks), social capital and intergenerational developments;
Access to cash transfers and social services
Wave 1 of the panel survey, conducted in 2008, collected the detailed information for the national sample.
Waves 2 to 4 of the panel survey re-interviewed respondents interviewed in previous waves, gathering information on developments in their lives over the years.

Version
Version Description
v2.0.0: Edited, partially anonymised dataset for use in DataFirst's Secure Research Data Centre
Version Date
2018-08-13
Version Notes
Version 1 of the National Income Dynamics Study wave 4 2014-2015 public release dataset was produced on the 12th of May 2016
CHANGES IN VERSION 1.1
Version 1.1 had changes to the weights variables, w3_pweight in the indderived data file and the w3_wgt in the hhderived data file. Changes to these variables were necessary because:
1.Panel weights were missing for some babies born to CSM mothers after Wave 1 (2008)
2. The weight was missing for one (now adult) respondent
CHANGES IN VERSION 2.0.0
Version 2.0.0 of NIDS wave 4 includes changes to the number of individuals and households in each data file, largely driven by previously incorrect classification of TSM/CSM status, duplicate interviews and additional baby CSMs not captured in a previous version of this wave. Version 2.0.0 also contains new and renamed variables, and there are changes to the survey weights. For details on these changes please see the document Wave 4 Changes between V1.1 and V2.0.0 which is provided with the data.

Scope
Notes
Data on the following topics was collected during the panel survey:
HOUSEHOLD: Household characteristics, household roster, mortality history, living standards, expenditure, consumption, negative events, positive events, agriculture
ADULTS: Demographics, education, labour market participation, income, health, well-being, numeracy, anthropometric data
CHILDREN: Education, health, family support, grants, anthropometric data, numeracy
The Secure (Restricted access) data files contain confidential variables that are not released in the publicly available data. The secure variables include the primary sampling unit (PSU), date of birth day, and full geo-codes. Employment codes are provided up to the four digit level, and a code-list for these is available with the data. A complete list of variables available in the restricted-access data is provided with the data.
