Scope
The surveys gather information on food insecurity, changes in employment, income loss, access to health services and education, and coping mechanisms, as well as households' quarantine compliance and their knowledge of the disease. Eligible respondents for the HFPS were adults 18 years old and above. Only one respondent per household was interviewed, and she answered both individual and household-level questions. The same respondent was contacted and interviewed in all waves.
Coverage

Sampling
Sample is based on a dual frame of cell phone and landline numbers generated through a Random Digit Dialing (RDD) process. In the first phase, a large sample was selected in both frames, and then screened through an automated process to identify the active, eligible numbers. A smaller second-phase sample was selected from the active residential numbers from in the first-phase sample and was delivered to the country teams. See Sampling Design and Weighting document for more detail.
The HFPS has two sample units: households and individuals. Sampling weights were computed for each unit and should be used according to the estimate of interest. The weighting process involves four steps:
- Calculation of the inclusion probabilities of landline and cell phone numbers.
- Computation of base weights for households and individuals.
- Nonresponse weighting adjustment.
- Calibration of individual and household weights, using external data from official sources (adjusted for the national phone coverage).
Survey instrument
Questionnaires are available in Spanish. The questionnaire for the first wave followed closely the World Bank’s HFPS Global Core Questionnaire but had some critical variations. There were also some modifications in the subsequent waves.
