How deep do the data go? This report systematically measures a specific set of inputs, outputs, and outcomes across Wikimedia programs in order to learn about evaluation and reporting capacity as well as programs impact. Importantly, it is not a comprehensive review of all program activity or all potential impact measures, but of those program events for which data was accessible through voluntary and grants reporting. Read this page to understand what the data tells you about the program and what it does not.
Response rates and data quality/limitations 
Data was received for a total of 19 WPWP Campaigns in 2020.
These Data were collected from three sources:
(1) from the Campaign organizers directly;
(2) from publicly available information on organizer project page and on-wiki reports; and (3) through WMF Labs tools such as the hashtag tool.
Through these sources we were able to collect information about: The Campaign priority goals, donated resources, budgets, staff and volunteer hours contributed, number of participants, number of new users, user retention, number of media files used on Wikipedia articles, and the number of language Wikipedia improved In total, we evaluated 23 WPWP Campaign implementations in 2021.

Values for a number of the key metrics were only reported for a minority of events, and in the cases of budgets and volunteer and staff hours these values could not be mined from other sources. Furthermore, data for the campaign were not normally distributed; the distributions are, for the most part, skewed. This is partly due to small sample size and partly to natural variation, but does not allow for comparison of means or analyses that require normal distributions. Instead, we present the median and ranges of metrics and use the term average to refer to the median average, since the median is a more statistically robust average than the arithmetic mean.’’ To give a comprehensive picture of the distribution of data, we include the means and standard deviations as references.
Local organizers reported the priority goals for the WPWP Campaign events in 2021. The two most popular goals were (1) to increase contributions to Wikimedia projects and (2) to build and engage communities.
Participants reported the priority goals for the WPWP Campaign. The two most popular goals were (1) to increase accuracy and/or quality of Wikipedia articles and (2) to increasing readers' satisfaction.
A total of 23 local organizers reported their "priority" goals for their WPWP Campaign events in 2021.
As shown in the table below, four/FIVE priority goals were selected by over 52% of reporting local organizers. The most popular goal, noted as a priority by at least 65% of program leaders, was to increase contributions to Wikimedia projects. About OR OVER 52.5% of local organizers stated that increasing accuracy and/or quality of contributions, increasing readers' satisfaction, increasing using of Wiki Loves Photos, and building and engaging the community, were the priority for their campaign.
