Diplometrics

Original datasets for studying diplomacy, power, influence, and geopolitical relationships

Diplometrics is Pardee’s data-building program for measuring international relationships that are often discussed qualitatively but difficult to compare systematically.
Managed by Pardee’s geopolitical analysis team, the program builds datasets, tools, and analyses that help users study diplomatic ties, leader travel, national power, bilateral influence, atrocity risk, international organizations, and related forms of engagement across countries and over time.

Datasets that make visible and quantifiable the harder-to-see dynamics of diplomatic behavior, influence, and state relationships.

The Diplometrics datasets

Diplometrics is organized around a practical problem: international relationships shape global outcomes, but many of those relationships are hard to observe, compare, or track over time. Each dataset below approaches that problem from a different angle, giving users a way to study how states, leaders, institutions, and networks interact across the international system. Each card below links to a dedicated page that hosts the dataset and provides more detail on coverage, definitions, methods, access, and citation guidance.
The datasets are designed for different questions, but they share a common purpose: to make selected geopolitical relationships more visible, comparable, and open to scrutiny.

About Diplometrics

What Diplometrics helps users study
Diplometrics helps users translate selected international relationships into comparable evidence. Researchers can use the datasets to study patterns in diplomacy, power, influence, cooperation, international organization activity, and risk. Policy and practitioner audiences can use them to compare relationships across countries, test assumptions, and ground analysis in documented measures. Students use the program to learn how international relations data are collected, coded, cleaned, and interpreted.

That evidence is useful on its own, but it also strengthens Pardee’s broader geopolitical analysis. By measuring relationships across countries and over time, Diplometrics gives analysts a clearer basis for studying how diplomacy, influence, capacity, and risk interact with longer-term political and development trends.
How Diplometrics datasets connect to Pardee's broader analysis
Some Diplometrics datasets stand alone as open research resources. Others support Pardee’s IFs-based geopolitical modeling, including bilateral analysis of trade, aid, diplomacy, and influence. In both cases, the purpose is the same: make assumptions, relationships, and evidence easier to examine.

The program grew from this same need for more systematic evidence. What began as a focused effort to measure power and diplomatic representation has expanded into a wider portfolio of datasets for studying how countries connect, compete, cooperate, and project influence.
The genesis of Diplometrics
Diplometrics began in 2011 as a data-building and analysis effort focused on national power, diplomatic representation, international organization membership, and multilateral treaty activity. Since then, the program has expanded to include datasets on military capabilities, non-state actors, leader travel, diplomatic capacity, cultural affinity, power projection, perceived mass atrocities, and bilateral influence.

As the portfolio has grown, Diplometrics has become a research infrastructure for studying bilateral relationships, networks, and geopolitical influence across the international system.

The timeline below shows how Diplometrics moved from early data-building around national power and formal diplomacy toward a broader research infrastructure for studying bilateral relationships, networks, and geopolitical influence.
The complete Diplometrics timeline

Diplometrics began as a data building and analysis project in 2011, focusing initially on developing and forecasting the first iteration of the Global Power Index and measures of diplomatic representation, membership in international organizations, and signing and ratification of multilateral treaties. The Global Power Index is a measure of national power featured in the National Intelligence Council’s Global Trends 2030 report.

Since 2011, the Diplometrics Program has expanded significantly to include data on military capabilities, non-state actors, foreign travel by heads of government and state, diplomatic capacity, cultural affinity, power projection, and other data initiatives. With the completion of the Global Indicators of Dyadic Engagement dataset in 2020, the Frederick S. Pardee Institute for International Futures has begun to use the combined data to analyze and forecast bilateral and networked influence across the international system. Additionally, the Institute has utilized its Formal Bilateral Influence Capacity Index, which is built in part from core Diplometrics data series, to launch a report in association with the Atlantic Council focusing on China-U.S. competition in Southeast Asia and implications for U.S. foreign policy.

As the portfolio expanded, the team placed more emphasis on sharing datasets, documentation, and analysis with researchers, analysts, policymakers, students, and the public. Through academic publications, commentaries, media interviews, and other public engagements, we seek to share our data and analysis with the world.

Over the years, the Diplometrics Program has been funded by: the U.S. Army Future Studies Group; the U.S.Army Research Office; the U.S. Department of Defense Minerva Research Initiative; and other partners. Along the way, hundreds of students have contributed to the Diplometrics Program in meaningful ways. As work on Diplometrics moves forward, their continued support will ensure our institute continues to develop original analyses and advance conversations in the international relations space among policy­makers, academics, and the public.

Methods, access, and citations

Because Diplometrics is built for research use, access and documentation matter as much as the datasets themselves. Users should be able to understand what each dataset measures, where the data come from, how coding decisions were made, and what limits should guide interpretation.
Each dataset page should identify what the dataset measures, where the data come from, how key coding decisions were made, what geographies and years are covered, and what limits should guide interpretation.
Datasets are linked through their individual pages. Where available, pages include public repositories, codebooks, dashboards, replication materials, or related journal articles.
Users should cite the dataset, codebook, or related publication listed on the relevant dataset page.
The datasets are also the foundation for Pardee’s published analysis. The resources below show how Diplometrics has been used in peer-reviewed research, policy-facing work, and public analysis of diplomacy, power, influence, and risk.
