Abstract
The National Income Dynamics Study - Coronavirus Rapid Mobile Survey 2020 investigates the socioeconomic impacts of the national lockdown associated with the State of Disaster declared in South Africa in March 2020, and the social and economic consequences in South Africa of the global Coronavirus pandemic. NIDS-CRAM forms part of a broader study called the Coronavirus Rapid Mobile Survey (CRAM) which aims to inform policy using rapid reliable research on income, employment and welfare in South Africa, in the context of the global Coronavirus pandemic. The study is run by researchers from the University of Stellenbosch, University of Cape Town (UCT) and University of the Witwatersrand (Wits). The NIDS-CRAM survey data collection and production operations were implemented by the Southern Africa Labour and Development Research Unit (SALDRU) at UCT. The data is collected with Computer Assisted Telephone Interviewing (CATI), with data collection repeated over several months.

Version Notes
The following changes were made in NIDS-CRAM Wave 3 version 2.0.0.
NIDS-CRAM_Wave3_Anon_V2.0.0
Some cases were corrected in variable w3_nc_ems_oct (and some variables thereafter in Section C of the questionnaire) from "2. No - I'm employed" to "No, I did nothing" because of a Zulu translation error. Because of the skip patterns subsequent questions in the skip sequence needed to be changed to "-3. Missing" or system missing, where appropriate.
5 non-response respondents had data filled in for the first few questions in error. All variables excluding those from Section A of the questionnaire therefore were corrected by having the responses set to system missing.
derived_NIDS-CRAM_Wave3_Anon_V2.0.0
To correct a Zulu translation error, 20 observations in variable w3_nc_empl_stat were changed from “3. Employed” to -8. Refused
Three new weight variables (w3_nc_pweight_s and w3_nc_pweight_extu_s w3_nc_bp_pweight_s) were added because the weights were scaled to the NIDS W5 population totals and the weights algorithms were updated.
Changes made from version 2.0.0. to version 3.0.0. of the Wave 3 data were minor data cleaning and data quality error corrections to all the variables.

Scope
Notes
The NIDS-CRAM Survey collects data on the following for households and household members:
- Demographics (age, gender, race)
- Labour and income (education, employment, income, occupation, threats to business/income from the lockdown), pensions and government grants, financial support)
- Household and Social (housing type, household size, access to water and electricity)
- Health and COVID-19 (behavior and knowledge related to COVID-19, tests, infections, symptoms, health facility visits, health conditions, access to medical insurance).
- Demographics (age, gender, race)
- Labour and income (education, employment, income, occupation, threats to business/income from the lockdown), pensions and government grants, financial support)
- Household and Social (housing type, household size, access to water and electricity)
- Health and COVID-19 (behavior and knowledge related to COVID-19, tests, infections, symptoms, health facility visits, health conditions, access to medical insurance).
Coverage
Geographic Coverage
National coverage, as NIDS was only designed to be nationally representative, it is inadvisable to use the NIDS-CRAM data to calculate provincial or regional totals.
Geographic Unit
The NIDS-CRAM data is at the country level only.
Universe
The universe of the study is South Africans 18 years old or older.

Sampling
Sampling Procedure
The sample frame for NIDS-CRAM is the NIDS Wave 5 CSMs and TSMs who were 18 years or older at the time of the NIDS-CRAM Wave 1 fieldwork preparation in April 2020. The sample was drawn using a stratified sampling design. No attempt was made to check whether successfully re-interviewed individuals resided in the same households as they did in Wave 5. In the survey, individuals from larger households were more likely to be sampled than individuals from smaller households.
Weighting
The weighted NIDS-CRAM survey data reflects the outcomes in 2020 for a broadly representative sample of South Africans 15 years and older from NIDS Wave 5 in 2017 who were followed up 3 years later.

Data Collection Notes
The NIDS-CRAM survey data collection and production operations were implemented by the Southern Africa Labour and Development Research Unit (SALDRU) based at the University of Cape Town. CATI interviews were conducted in the preferred official South African language of respondents.
Questionnaires
Questionnaires
Though NIDS-CRAM is a follow-up with NIDS Wave 5 respondents, the NIDS-CRAM survey uses a much shorter questionnaire, with a focus on the Coronavirus pandemic and the national lockdown. The questionnaire was changed slightly across waves and data users should check the questionnaires for each wave when using the data.
