COVID-19 LAC High Frequency Phone Surveys 2021, Wave 1 - Dominica

Abstract
---------------------------

After implementing Phase 1 of the High-Frequency Phone Survey (HFPS) project in Latin America and The Caribbean in 2020, the World Bank conducted Phase 2 in 2021 to continue to assess the socio-economic impacts of the COVID-19 pandemic on households. This new phase, conducted in partnership with the UNDP LAC Chief Economist office, included two waves. Wave 1 collected between May and July 2021, covering 23 countries. Of these countries, 13 participated in Phase 1: Argentina, Bolivia, Colombia, Costa Rica, Chile, Dominican Republic, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Paraguay and Peru. Countries that joined in Phase 2 are: Antigua & Barbuda, Belize, Dominica, Guyana, Haiti, Jamaica, Nicaragua, Panama, St. Lucia and Uruguay.

This study presents information from these 23 countries. Brazil was later integrated into the LAC HFPS Phase 2 project.

Households and individuals of 18 years of age and older.

Sampling procedure
---------------------------

Phase 2 Wave 1 samples for the Original Countries included two components: a) a panel formed by respondents to Phase 1 Wave 1, and b) a supplement fresh sample of phone numbers to compensate for attrition between Phase 1 Wave 1 and Phase 2 Wave 1, and to slightly increase the overall sample size. 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. See Sampling Design and Weighting document for more detail.
