Socio-Economic/Monitoring Survey [hh/sems]
These surveys are the final delivery of the series of LAC: COVID-19 High Frequency Monitoring Project (Phase1 - P173987) & (Phase 2- P175839).
This study presents information from 23 countries for which data was collected between May and July 2021. Brazil was integrated into the LAC HFPS Phase 2 project at a later point and was implemented with a slightly different approach. See the project information here: https://microdata.worldbank.org/index.php/catalog/4533. For information on the LAC HFPS Phase 1, see here:

Households and individuals of 18 years of age and older.
Version
Edited, anonymized dataset for public distribution.
2023-01-09
The new version is a cleaner version of the previous for surveys included in COVID-19 LAC High Frequency Phone Surveys 2021, Wave 2. Version update includes: a) For the data: removal of variables containing all missing values that were created when modules were not applicable to the country. These variables should have been omitted from the previous version, they were dropped from the updated version; and b) For the supporting documents: removal of color coding used for proofreading questionnaires and modules and certain questions not implemented in the field; and a formatted version of the note describing the sampling procedure.
Scope
The 2021 HFPS collects information on changes in employment and income, prevalence of food insecurity, access to health, education, and financing services. This allows users to compare certain indicators of living conditions of households and individuals with the 2020 HFPS. Additionally, the 2021 phase gathered information on access and use of internet and digital banking services, gender issues, mental health, coping mechanisms and childcare. As in the first phase, the surveys are representative of individuals of 18 years of age or above who have an active cellphone number or a landline at home. An improvement in the sampling methodology also allows for the data of Phase 2 Wave 2 to be representative of school-age children and adolescents for the education module, and childcare for children up to 5 years old. Finally, in Wave 2, a representative sample of minorities was obtained in seven countries (Bolivia, Guatemala, Mexico, Panama, Dominican Republic, Peru, and Colombia).
Eligible respondents for the HFPS were adults 18 years old and above. Only one respondent per household was interviewed, and he/she answered individual, child and household-level questions.

Sampling
The size of the Phase 2 Wave 2 overall (cell phones and landlines) selected sample of phone numbers (i.e., before any fieldwork activities) in each of the Original Countries (i.e. the 13 countries included in LAC HFPS Phase 1) is equal to the Phase 1 Wave 1 overall selected sample of phone numbers, plus the Phase 2 Wave 1 overall supplement fresh sample, plus the Phase 2 Wave 2 overall supplement fresh sample of phone numbers.
The samples of the Added Countries (i.e. those only included in Phase 2) 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. Please see Sampling Design and Weighting document for more detail.
HFPS Phase 2 has three units of analysis: households, adult individuals (18 years of age and older), children 0-5 years old, and children 6 through 17 years of age. Weights were computed for each sample unit and should be used according to the estimate of interest.
The weighting process for the 13 Countries included in LAC HFPS Phase 1 involve five steps:
- Calculation of the inclusion probabilities of landline and cell phone numbers.
- Computation of design weights for households and individuals.
- Attrition nonresponse weighting adjustment for the panel sample component, and first-time nonresponse adjustment for the supplement sample component.
- Calibration of household, adult and child/adolescent weights, using external ancillary data from official sources (adjusted by national phone coverage).
- Weight trimming and recalibration.
The sample design and weighting procedures for new countries are the same ones used for the Original Countries in Phase 1 Wave 1.

Data collection
| Start | End | Cycle |
|---|---|---|
| 2021-10-11 | 2022-01-11 | Wave 2 |
- Computer Assisted Telephone Interview [cati]
Sistemas integrales jointly with the World Bank and UNDP teams were in charge of all supervision activities.
In wave 2, the project collected information from individuals who were also interviewed in Wave 1. Due to attrition, not all individuals who participated in Wave 1 were re-interviewed. Individuals who were interviewed in both waves can be identified through the variable "tipo_muestra". Relatedly, in a few cases individuals provided answers in Wave 2 that were not fully consistent with the answers provided in Wave 1. Such potential inconsistencies are flagged through dummies in the dataset.
