South Africa - National Income Dynamics Study 2010-2011

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 survey, conducted in 2008, collected the detailed information for the national sample. In 2010/2011 Wave 2 of NIDS re-interviewed these people, gathering information on developments in their lives since they were interviewed first in 2008. As such, the comparison of Wave 1 and Wave 2 information provides a detailed picture of how South Africans have fared over two years of very difficult socio-economic circumstances.

国民收入动态追踪研究（National Income Dynamics Study，NIDS）是一项针对南非境内居民及其家庭开展的面对面纵向追踪调查。本调查旨在全面展现南非民众福祉的多维度内涵，并实现对其随时间变化的追踪。从最宏观的层面来看，这些维度包括：
- 基于收入与支出动态变化及资产禀赋的财富创造状况；
- 与家庭结构及人口迁移相关的人口动态特征；
- 社会传承维度，涵盖教育与就业动态变化、人生事件（包括正向与负向冲击）的影响、社会资本及代际发展情况；
- 现金转移支付与社会服务的可及性。

该调查的第一波数据采集于2008年，为全国代表性样本收集了详尽的调研信息。2010至2011年开展的NIDS第二波调查对上述受访对象进行了回访，收集了他们自2008年首次受访以来的生活变迁相关信息。因此，对比第一波与第二波的调查数据，可以全面呈现南非民众在这两年极为艰难的社会经济环境中的生活境况与变化。
