Appendix 2: Methodology The primary data in this report come from the Gallup World Poll, through which Gallup has conducted surveys of the world's adult population, using randomly selected samples, since 2005. The survey is administered annually face to face or by telephone, covering more than 160 countries and areas since its inception. In addition to the World Poll data, Gallup collected extensive random samples of working populations in the United States and Germany; these samples were also added to the dataset. The target population of the World Poll is the entire civilian, noninstitutionalized, aged-15- and-older population. Gallup's data in this report reflect the responses of adults, aged-15- and-older, who were employed for any number of hours by an employer. With some exceptions, all samples are probability-based and nationally representative. Gallup uses data weighting to minimize bias in survey-based estimates; ensure samples are nationally representative for each country; and correct for unequal selection probability, nonresponse and double coverage of landline and mobile phone users when using both mobile phone and landline frames. Gallup also weights its final samples to match the national demographics of each selected country. Regional findings in this report include data obtained from 2021 to as late as March 2022 (reported as part of 2021 data in this report). To determine percentage point changes for regions, Gallup uses data from 2020 and 2021 from the same countries in each region. Country-specific findings in "Appendix 1: Country Comparisons" are based on data aggregated from three years of polling (2019, 2020 and 2021 — with several countries' 2021 data obtained in early 2022). Percentage point changes for countries indicate the differences in percentage points when comparing the average from 2018, 2019 and 2020 with the average from 2019, 2020 and 2021. Gallup typically surveys 1,000 individuals in each country or area, using a standard set of core questions that has been translated into the major languages of the respective country. In some countries, Gallup collects oversamples in major cities or areas of special interest. Additionally, in some large countries, such as China and Russia, sample sizes include at least 2,000 adults. In a small number of countries, the sample size is less than 1,000. In this report, Gallup does not provide country-level data (aggregate of 2019, 2020 and 2021 data) or country-level percentage point change data (aggregate of 2018, 2019 and 2020 data) for any country that has an aggregate n size of less than 300. For results based on the total sample of adults globally, the margin of sampling error ranged from ±0.5 percentage points to ±0.7 percentage points at the 95% confidence level. For results based on the total sample of adults in each region, the margin of sampling error ranged from ±0.6 percentage points to ±5.0 percentage points at the 95% confidence level. For results based on the total sample of adults in each country, the margin of sampling error ranged from ±0.5 percentage points to ±8.5 percentage points at the 95% confidence level. All reported margins of sampling error include computed design effects for weighting. Copyright © 2022 Gallup, Inc. All rights reserved.
