The National Income Dynamics Study (NIDS) is the first national household panel study in South Africa. It is part of an intensive multi-million rand effort on the part of the government to track - and understand - the shifting face of poverty.

In 2008 the first wave of data collection began when about 300 fieldworkers spread out in all nine provinces of the country in search of the 28 000 people that formed part of the 7 305 selected households. The survey is designed to reveal information about internal migration, birth and death, savings, health, education and household spending patterns. The Wave 1 NIDS data was made public at the end of July in 2009.

The year 2010 marked the second wave of data collection, visiting the same respondents that were visited in 2008. Those that had moved from their original households were tracked if their movements were within the borders of the country. Data from Wave 2 was released in 2012.  

In September 2013 the Wave 3 data was released after visiting 11 842 dwellings and interviewing some 32 633 people.  This was a particularly successful wave with a negative attrition yielding of 5.09% more sample members interviewed than the previous wave.
