COVID-19 LAC High Frequency Phone Surveys 2021, Wave 2 - Argentina

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 covering 24 countries. Wave 2 collected between October and December 2022, covering 22 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 and Brazil (only in Wave 1), Belize, Dominica, Guyana, Haiti, Jamaica, Nicaragua, Panama, St. Lucia and Uruguay.

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.

Geographic coverage

National level

Analysis unit

Households and individuals of 18 years of age and older.

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

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.

2020年，世界银行在拉丁美洲和加勒比海地区实施了高频电话调查（HFPS）项目的第一阶段，并于2021年启动第二阶段，以持续评估COVID-19大流行对家庭的社会经济影响。本新阶段与联合国开发计划署拉丁美洲和加勒比海地区首席经济学家办公室合作开展，包括两个波次。第一波次覆盖24个国家。第二波次于2022年10月至12月间进行，覆盖22个国家。其中，13个国家参与了第一阶段：阿根廷、玻利维亚、哥伦比亚、哥斯达黎加、智利、多米尼加共和国、厄瓜多尔、萨尔瓦多、危地马拉、洪都拉斯、墨西哥、巴拉圭和秘鲁。在第二阶段加入的国家有：安提瓜和巴布达及巴西（仅在第一波次）、伯利兹、多米尼克、圭亚那、海地、牙买加、尼加拉瓜、巴拿马、圣卢西亚和乌拉圭。

本研究提供了2021年5月至7月间收集的23个国家的信息。巴西在拉丁美洲HFPS第二阶段项目中后期加入，并采用了略有不同的实施方法。有关项目信息，请参阅：https://microdata.worldbank.org/index.php/catalog/4533。关于LAC HFPS第一阶段的信息，请参阅：

抽样程序
---------------------------
第二阶段第二波次总体（手机和固定电话）选定样本的号码数量（即，在实地工作活动之前）在每个原始国家（即LAC HFPS第一阶段包括的13个国家）中等于第一阶段第一波次总体选定样本的号码数量，加上第二阶段第一波次总体补充新鲜样本，加上第二阶段第二波次总体补充新鲜样本的号码数量。

新增国家（即仅在第二阶段包括的国家）的样本基于通过随机拨号（RDD）过程生成的手机和固定电话号码的双重框架。在第一阶段，两个框架中均选取了大量的样本，然后通过自动化流程筛选以识别活跃且合格的号码。从第一阶段样本中的活跃住宅号码中选取了较小的第二阶段样本，并将其交付给国家团队。更详细的抽样设计和加权信息请参阅《抽样设计和加权》文件。
