Executive Summary

Ongoing efforts to partner with our clients “in the seam,” through thought leadership activities not directly tied to specific project dissemination, contributed to improvements in most engagement metrics in the fourth quarter (Q4) of 2021. In addition, focusing our content on timely and topical issues, such as climate change and equity, helped raise awareness of Mathematica’s expertise in ecosystems that are relatively new to us. The quarter’s highlights include the following:

  • An almost 50 percent increase in new subscribers to our email list, compared with the third quarter (Q3)
  • An ongoing surge in new visitors to our website, surpassing returning visitors by more than 4:1
  • Almost 5,000 views of our climate action page, with visitors averaging 6 additional page views
  • 28 external guests featured on our podcast—the highest in any quarter to date—as we share our platforms to lift up diverse voices and perspectives
  • Expanded reach of our social media content, with 30 percent and 15 percent increases in impressions and followers, respectively


In Q4 of 2021, there were 297,000 page views and 160,000 visits to mathematica.org, compared with 307,000 page views and 167,000 visits in Q4 2020. A year-long trend of attracting at least 50,000 visits and 95K page views per month continued through December 2021.

Quarterly Content Campaigns

To advance our mission and vision and to support the objectives of Mathematica’s 2021–2024 strategy, Communications is expanding our presence and engagement in key ecosystems. We are executing quarterly thematic campaigns that focus on crosscutting, timely, and strategic topics that position Mathematica as a leader on critical and emerging issues and engage evidence communities.

In Q4, the content focus was Climate Action Guided by Data. We featured climate- and energy-related content on a centralized landing page and amplified this thought leadership and project content via email, social media, and search engine optimization. The campaign landing page earned 4,784 page views, exceeding views for any other campaign page to date. Visitors to the landing page viewed an average of six additional pages after they viewed the climate action campaign landing page, doubling the average subsequent page views earned in Q3.

During the Q4 content campaign on climate action, we showcased Mathematica’s interdisciplinary, multi-sectoral climate expertise using digital-first products, including the following:

  • Events - We hosted a webinar, "Evidence-Informed Climate Action," with leaders from the International Fund for Agricultural Development, the Millennium Challenge Corporation, and the U.S. Agency for International Development (USAID), discussing climate change and strategies for using evidence to inform responses to the growing climate crisis. Additionally, we held an Ask Me Anything session on Twitter Spaces featuring Esteban Quinones and Anthony D’Agostino, discussing opportunities to apply data for climate action.
  • Blogs - We published four blogs on topics including workforce policies, the food and agriculture sector, and staff profiles, earning a total of more than 2,100 views. The staff profiles, featuring Esteban Quinones and Tulika Narayan, were two of the top five best performing blog posts in Q4.
  • Social media - We produced an animated social media video on taking Climate Action guided by data, earning ~250 views on Twitter alone.

In Q1 2022, our focus will pivot to our new content campaign, Lead Change with Evidence-Based Decision Making.


Mathematica’s blog attracted almost 42,000 page views during Q4 2021, up from about 29,500 in Q3 (42 percent increase) and the highest quarterly total of 2021. Visits to the blog accounted for more than 9.7 percent of all website traffic during the quarter. A total of 27 new posts were added during the fourth quarter, bringing the total number of posts for 2021 to 105, just behind 2020’s record pace of 111.

Site users continued to spend more than twice as much time on individual blog posts (3:18) as the page average for the full website (1:14). In addition, the blog continues to be a primary entry point for users, with 12.4 percent of users entering the site through a blog post. While both Q4 and 2021 metrics are down from the historic highs of 2020, Q4 2021 traffic was 73.5 percent higher than the same quarter of 2019, with total blog page views in 2021 nearly doubling the 2019 benchmark.

Posts from our My Mathematica series, which offer readers a look at the people behind our work and the passions that drive it, continue to lead the way in terms of our most popular posts for the quarter (3,334 page views) and the year (6,363 page views). We look forward to building on this momentum with monthly My Mathematica features in 2022.

In addition, a number of equity-focused posts performed well this quarter, including Dawnavan Davis’ look at how we’re working to center equity, the write-up of our November podcast on how and why foundations are pushing to advance equity through evidence, and a project-funded post authored by our partners at the Bill and Melinda Gates Foundation on the importance of equity-centered strategic learning.

Unlike last quarter, 8 of the top 10 most viewed posts in Q4 2021 were posted during the quarter, with popular posts from 2020 about learning during the pandemic and the 19 and Me Risk Calculator as the only outliers.

On the Evidence

In Q4 2021, Mathematica’s podcast garnered the second-most listens in any quarter since the podcast began in February 2019. The strong showing is owed in part to a more consistent output of episodes, with six episodes publishing in Q4 compared to four in Q2 and Q3 and five in Q1. But it's not simply that we published more episodes—individual episodes also appear to be generating more listens. The average number of listens per episode within the first two weeks of publication was up 17 percent from 2020 to 2021. The final quarter reflected trends that are likely to continue into 2022: an increase in the number of guests per episode, the inclusion of project-funded episodes, and more episodes that amplify messages and themes in the 2021–2024 enterprise strategy and 2035 vision.

More guests: We had featured 28 guests in Q4 (the most of any quarter to date), which reflects ongoing efforts to share our platforms and deepen our collaboration with a diverse range of external partners whose expertise and lived experiences supplement our perspectives.

Project-funded episodes: The podcast is demonstrating value as a client-centric approach to dissemination and thought leadership. One episode focused on removing child care barriers for parents participating in job training through the Strengthening Working Families Initiative. A second project-funded episode focused on advancing racial equity in fatherhood programs.

Amplifying strategic messages and themes: We continue to strengthen the alignment of podcast episode topics with the messages and themes of our mission, vision, and strategy. For example, in Q4, one episode focused on the theme of diversity, equity, and inclusion (DEI) and digital transformation through the lens of the Summer Institute for Computational Social Scientists, co-sponsored by Mathematica and Howard University. Another episode focused on promoting DEI in policy research by hosting a discussion of philanthropy’s role in promoting culturally responsive and equitable research.

Other examples of our social media work in Q4 include the following:

  • We presented a year-end edition of the #PrimaryCareCovidChat, for which Communications and the Health unit partnered to conclude the popular Twitter chat that we launched in the spring of 2020 and which has earned more than 3 million impressions. In 2022, this regular gathering of primary care thought leaders will become the #PrimaryCarePolicyChat.
  • We were invited to be a judge of the 2022 International Association of Business Communicators Gold Quill Awards, based on our record of having twice won the award for our social media content.
  • With partners from our International unit, we hosted the second in our series of Ask Mathematica Anything events via Twitter Spaces, a new audio-only platform that allows us to share our expertise in an open, conversational forum. In doing so, we’ve positioned ourselves to take full advantage of this new thought leadership opportunity as it continues to grow in popularity.
