## Brand AwarenessEdit

*n*= 4249 for all contributors responding to the question, 83.7% responding "yes" (95% CI: 82.6%, 84.8%). Respondents who finished less than 50% of the survey were less likely (81.1%) to indicate "yes" (*n*= 2531,*χ*^{2}= 31.306,*p*= 0.000), though this effect size was quite small (𝜑 = 0.088). When compared to respondents on other continents, a Pearson*χ*^{2}test found awareness of the Wikimedia Foundation was higher among those in Northern America (*n*= 166,*χ*^{2}= 12.481,*p*= 0.000) and lower for those in South America (*n*= 155,*χ*^{2}= 13.175,*p*= 0.000) and Eastern Europe (*n*= 221,*χ*^{2}= 6.357,*p*= 0.012). A Fisher’s exact test found Foundation awareness was also lower in Central America (*n*= 26,*p*= 0.002).*n*= 4434 for all contributors responding to this question in 2018.- “How well does this vision represent your values…” (
*n*= 3975, average score 3.31, 95% CI: 3.29, 3.34. Those who finished less than 50% of the survey had a lower average score of 3.28,*n*= 2197,*U*= 1,193,970.5,*p*= 0.005), though this effect size was very small (*r*= 0.001). “The Wikimedia Foundation has the right programs and strategies…” (*n*= 2284, average score of 3.76, 95% CI: 3.72, 3.80). “I am confident in the Wikimedia Foundation’s ability to support the global movement” (*n*= 3021, average score of 3.68, 95% CI: 3.65, 3.72. Those who finished less than 50% of the survey had a lower average score of 3.64,*n*= 1459,*U*= 690,065,*p*= 0.002), though this effect size was very small (*r*= 0.001). - Foundation Support is calculated by averaging responses to the three index questions (or those index questions responded to), standardized to a scale of 1 to 5. A Foundation Support score (FSS) was calculated for 4080 contributors who answered any combination of the three index questions (average FSS score was 3.92, 95% CI: 3.89, 3.94). For the following statistical tests, results of a
*t*-test are reported for clarity even though assumptions of normality and outliers are violated. A Mann-Whitney*U*-test is used in each case to confirm findings. When compared to other contributors, an independent samples*t*-test found average FSS to be higher for those living in Africa (4.36,*n*= 21,*t*= -2.778,*p*= 0.006; mean rank of 851.94 compared to 618.11,*U*= 15164,*z*= 2.754,*p*= 0.006), Southern Asia (4.12,*n*= 66,*t*= -2.347,*p*= 0.019; mean rank of 741.79 compared to 617.39,*U*= 29552.5,*z*= 2.190,*p*= 0.028), and Northern Europe (4.03,*n*= 131,*t*= -2.012,*p*= 0.044; mean rank of 731.48 compared to 612.60,*U*= 63657,*z*= 3.084,*p*= 0.002). A similar test found average FSS to be lower among contributors living in Eastern Asia (3.64,*n*= 147,*t*= -4.172,*p*= 0.000, not assuming equal variances; mean rank of 490.59 compared to 635.89,*U*= 52717,*z*= -4.277,*p*= 0.000).

## Global AdvocacyEdit

*n*= 2101 for all contributors responding to the question, 95% CI: 64.6%, 68.6%. Respondents who finished less than 50% of the survey were less likely (61.8%) to indicate policy knowledge (*n*= 584,*χ*^{2}= 8.224,*p*= 0.004). When compared to other respondents, a Pearson*χ*^{2}test found contributors living in Western Asia (*n*= 37,*χ*^{2}= 9.734,*p*= 0.002), Southern Asia (*n*= 56,*χ*^{2}= 13.916,*p*= 0.000), and South America (*n*= 152,*χ*^{2}= 11.178,*p*= 0.001), newcomers (*n*= 236,*χ*^{2}= 9.110,*p*= 0.003), on-wiki admins (*n*= 172,*χ*^{2}= 12.560,*p*= 0.000), and movement organizers (*n*= 493,*χ*^{2}= 94.016,*p*= 0.000, not weighted by editing activity) were more likely to indicate public policy knowledge in at least one area. Those in Northern America (*n*= 153,*χ*^{2}= 5.368,*p*= 0.021) and Western Europe (*n*= 327,*χ*^{2}= 28.784,*p*= 0.000) were less likely to indicate knowledge of public policy.*n*= 2831 for all contributors responding to the question, 95% CI: 15%, 17.2%. Respondents who finished less than 50% of the survey were less likely (14.0%) to indicate participation in policy advocacy (*n*= 1025,*χ*^{2}= 4.362,*p*= 0.037), though this effect size was quite small (𝜑 = 0.039).*n*= 2493 for all contributors responding to the question. 74.8% indicated that access was important (95% CI: 73%, 77%), 43% that free expression was most important (95% CI: 42%, 45%; respondents who finished less than 50% of the survey were less likely (40%) to say this was important (*n*= 729,*χ*^{2}= 4.320,*p*= 0.038), though this effect size was quite small (𝜑 = 0.042)), 29% that copyright was important (95% CI: 27%, 31%), 28% that privacy was important (95% CI: 26%, 29%), and 9.7% that intermediary liability was (95% CI: 8.5%, 11%; respondents who finished less than 50% of the survey were less likely (7.7%) to say this was important (*n*= 729,*χ*^{2}= 4.650,*p*= 0.031), though this effect size was quite small (𝜑 = 0.043)). A Fisher’s exact test found those in Africa more likely to value knowledge access than other contributors (*n*= 20,*p*= 0.007). Compared to other contributors, a Pearson*χ*^{2}test found those in Southern Asia (*n*= 63,*χ*^{2}= 3.924,*p*= 0.048) and South-eastern Asia (*n*= 50,*χ*^{2}= 6.078,*p*= 0.014) more likely to value access. Contributors in Eastern Asia (*n*= 144,*χ*^{2}= 39.660,*p*= 0.000) and on-wiki administrators (*n*= 185,*χ*^{2}= 4.340,*p*= 0.037) were less likely to value access. Contributors in Africa (*n*= 21,*χ*^{2}= 5.737,*p*= 0.017), Southern Asia (*n*= 63,*χ*^{2}= 7.070,*p*= 0.008), and South-eastern Asia (*n*= 50,*χ*^{2}= 9.087,*p*= 0.003) were less likely to value free expression, but those in Eastern Asia (*n*= 143,*χ*^{2}= 8.725,*p*= 0.003) and Southern Europe (*n*= 185,*χ*^{2}= 7.097,*p*= 0.008) to be less likely to do so. Contributors in South-eastern Asia were more likely to value privacy (*n*= 51,*χ*^{2}= 3.853,*p*= 0.050).

## Platform EvolutionEdit

*n*= 179 for all volunteer developers reporting the country in which they live.

For the following statistical tests, results of a*t*-test are reported for clarity even though assumptions of normality and outliers are violated. A Mann-Whitney*U*-test is used in each case to confirm findings. When compared to other contributors, an independent samples*t*-test found volunteer developers living in Europe to be less confident in the health and safety of the codebase (3.33,*n*= 63,*t*= 2.049,*p*= 0.042; mean rank of 65.67 compared to 78.63,*U*= 2121,*z*= -1.964,*p*= 0.050).

## Thriving MovementEdit

*n*= 1570 for all indicating both tenure (year when began contributing) and country or territory of residence. A Fisher’s exact test found new contributors more likely to live in Africa than tenured contributors (*p*= 0.007). A Pearson*χ*^{2}test also found new contributors more likely to live in Asia (*χ*^{2}= 46.400,*p*= 0.000) and Latin America or the Caribbean (*χ*^{2}= 5.619,*p*= 0.018), and less likely to live in Europe (*χ*^{2}= 35.299,*p*= 0.000) and Northern America (*χ*^{2}= 5.153,*p*= 0.023) than more tenured developers. Even though Oceania includes Melanesia, Micronesia, and Polynesia, the only respondents from this region lived in Australia and New Zealand.*n*= 1691 for all indicating gender identity. 86.9% identified as male (95% CI: 85.3%, 88.5%), and 11.6% identified as women (95% CI: 10.1%, 13.1%). A Pearson*χ*^{2}test found that newer contributors were more likely to identify as women (*χ*^{2}= 31.350,*p*= 0.000).- The source for a global estimate of metropolitan area populace is Moreno-Monroy A.I., Schiavana M., Veneri P. (2020). Metropolitan areas in the world. Delineation and population trends. Journal of Urban Economics, published online ahead of print, https://www.sciencedirect.com/science/article/pii/S0094119020300139.
*n*= 2382 for contributors responding to a question about rural/urban location, and 34.52% said they live in the country or in a small city or town (95%CI: 32.26, 36.79). A Pearson*χ*^{2}test found new contributors more likely to live outside of a metropolitan area (*χ*^{2}= 4.632,*p*= 0.031). *n*= 1545 for contributors indicating their level of education by number of years. 16 years of formal education was used as a reasonable equivalence for a 4-year college degree. A Pearson*χ*^{2}test found new contributors less likely to have 16 or more years of formal education (*χ*^{2}= 34.171,*p*= 0.000). Estimate of worldwide rates of post-secondary degree completion is sourced from Barro R., Jong-Wha L. (2013). A new data set of educational attainment in the world, 1950-2010. Journal of Development Economics, 104, 184-198.*n*= 244 for new contributors responding to “easy to learn editing policies” with an average score of 3.44 (95% CI: 3.31, 3.58).*n*= 253 for “easy to learn the editing tools” with an average score of 3.66, (95% CI: 3.53, 3.79).*n*= 243 for “I feel like I understand the rules” with an average score of 3.78 (95% CI: 3.67, 3.89).*n*= 251 for “learning to edit has been easy” with an average score of 3.85 (95% CI: 3.73, 3.97).*n*= 222 for “other editors have been kind” with an average score of 3.88 (95% CI: 3.77, 3.99).*n*= 228 for “other editors have been helpful” with an average score of 3.79 (95% CI: 3.67, 3.91). The Newcomer Empowerment Score is calculated by averaging responses to the six index questions (or those index questions responded to), standardized to a scale of 1 to 5. A score was calculated for 256 new contributors who answered any combination of the six index questions (average score was 3.74, 95% CI: 3.65, 3.83).- For the following statistical tests, results of a
*t*-test are reported for clarity even though assumptions of normality and outliers are violated. A Mann-Whitney*U*-test is used in each case to confirm findings. Newcomers who were youth had a higher average empowerment index than other newcomers (4.00,*n*= 66,*t*= -3.608,*p*= 0.000; mean rank of 104.46 compared to 79.45,*U*= 4235.5,*z*= 3.089,*p*= 0.002).

A Belonging index score was calculated for 1939 people responding to these questions, with an average score of 3.56 (95% CI: 3.52, 3.60). Those who finished less than 50% of the survey had a lower average score of 3.41,
*n*= 241,*U*= 134425.5,*p*= 0.003), though this effect size was very small (*r*= 0.002). The Engagement index is an averaged score of disagreement or agreement with five statements: (1) I would recommend Wikimedia projects as a great place to contribute; (2) The vision of the Wikimedia movement is to freely share in the sum of all knowledge. This vision inspires me to contribute more to Wikimedia projects than I would somewhere else; (3) I take pride in contributing to the Wikimedia projects; (4) I often think about quitting as a contributor to Wikimedia projects (scale reversed); and (5) I expect to be contributing to Wikimedia projects two years from now. An Engagement Index score was calculated for 2411 people responding to these questions, with an average score of 4.01 (95% CI: 3.98, 4.04).
