The data in this report are based on a survey of 108,946 Facebook monthly active users, aged 18 and older. The survey was conducted March 25 – April 14, 2022. Sampled Facebook users received an invitation to answer a short survey at the top of their Facebook News Feed and had the option to click the invitation to complete the survey on the Facebook platform.
The sample was drawn from the population of Facebook monthly active users, defined as registered and logged-in Facebook users who had visited Facebook through the website or a mobile device in the last 30 days.The Facebook monthly active users figure is reported in the company’s quarterly earnings report found on https://investor.fb.com. As of March 31, 2022, there were 2.94 billion monthly active users globally, including 263 million monthly active users in the U.S. and Canada. Within each country or territory surveyed, we drew a sample in proportion to publicly available age and gender benchmarks. The sample population in the United States was drawn in proportion to the U.S. Census Bureau Current Population Survey 2018 March Supplement. Sample populations for the geographic groups were drawn in proportion to the population of Facebook users due to lack of publicly available benchmark data. All other countries and territories were sampled in proportion to data from the United Nations Population Division 2019 World Population Projections.
Data for some countries and territories that have smaller populations and/or numbers of Facebook users were combined into “group” scores (i.e., Caribbean, Asian and Pacific Islands, and some countries in Sub-Saharan Africa). Some territories in the United Kingdom and France were also combined with national populations. Data were then weighted separately for each country, territory, and group using a multi-stage, pre- and post-survey weighting process based on census and nationally representative survey benchmarks, Facebook demographics, and Facebook engagement metrics, balanced to the total number of survey completions.Weights were generated in three stages. First, we adjusted for sampling in proportion to age and gender census benchmarks. Second, we adjusted for non-response error using Inverse Propensity Score Weighting (IPSW) on Facebook demographics and Facebook engagement metrics to make the sample more representative of Facebook monthly active users. The Facebook monthly active user sampling frame constitutes a sizable proportion of the global population, but the proportion of adults who use Facebook differs from country to country. To more closely reflect the entire adult population in a country or territory, we used poststratification based on publicly available nationally representative survey benchmarks, using weights from the first stages as inputs. The final weights were balanced to the total number of survey completions.
This project is a partnership between the Yale Program on Climate Change Communication and Data for Good at Meta. The survey instrument was designed by Anthony Leiserowitz, Seth Rosenthal, and Jennifer Carman of Yale University, with support by Nicole Buttermore, Kelsey Mulcahy, and J.W. Schneider at Meta. The survey was fielded by Meta. Survey weights were generated by Nicole Buttermore. The charts and maps were designed by Liz Neyens and Jennifer Marlon of Yale University.
Rounding error and tabulation
Percentages are weighted based on general population parameters for each surveyed country and territory.
For tabulation purposes, percentage points are rounded to the nearest whole number. As a result, percentages in a given chart may total slightly higher or lower than 100%. Summed response categories (e.g., “I definitely would do it” + “I probably would do it”) are rounded after sums are calculated (e.g., 25.3% + 25.3% = 50.6%, which, after rounding, would be reported as 25% + 25% = 51%).
Sample size for surveyed countries, territories, and groups
Our study collected data from a total of 192 countries and territories,Samples were drawn from two additional locations (Eritrea and Jersey), but no respondents participated in the surveys in these locations, so they are excluded from the final list. including 81 countries and territories that were collapsed into three geographic groups due to sample size (i.e., Caribbean, Asian & Pacific Islands, and Sub-Saharan Africa), three territories that were grouped with the United Kingdom, and one territory that was grouped with France. The unweighted sample sizes for each country, territory, and group are as follows:
*The 81 countries and territories were collapsed into the three geographic groups as follows:
Asian & Pacific Islands (n = 1,916):
Caribbean (n = 811):
Sub-Saharan Africa (n = 3,395):
