These surveys are part of the LAC: COVID-19 High Frequency Monitoring Project (P173987).
Latin American and the Caribbean is one of the regions in the world most affected by the COVID-19 pandemic. The World Bank conducted a series of High-Frequency Phone Surveys (HFPS) to assess the impact of the coronavirus pandemic on the welfare of Latin American and Caribbean households. Between March and August 2020, the HFPS collected nationally representative information for thirteen countries: Argentina, Bolivia, Chile, Colombia, Costa Rica, Dominican Republic, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Paraguay, and Peru.
Kind of Data
Sample survey data [ssd]
Unit of Analysis
Households and individuals of 18 years of age and older.
Version 01: Edited, anonymized dataset for public distribution.
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.
Households with a landline or in which at least one member has a cell phone, and individuals 18 years of age or above who have an active cell phone number or a landline at home.

Survey collection, supervision and quality control
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:
1. Calculation of the inclusion probabilities of landline and cell phone numbers.
2. Computation of base weights for households and individuals.
3. Nonresponse weighting adjustment.
4. Calibration of individual and household weights, using external data from official sources (adjusted for the national phone coverage).

Sistemas integrales was also in charge of all supervision activities.
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.
