Welcome to the Diplomatic Capacity Index
Tracking Global Investments in Diplomacy
The Diplomatic Capacity Index (DPI) measures the diplomatic resources that countries draw on to exercise influence on the global stage: their diplomatic infrastructure, access, leverageable advantages and global standing. By tracking the contents of the diplomat’s toolbox, the DCI offers policymakers and analysts a new baseline for assessing countries’ foreign relations and for directing resources to future diplomatic efforts. Through the index, users will be able to compare national diplomatic capacity with military and economic capacities for the first time.
The DPI currently comprises 80 indicators and three years of data for 30 countries to demonstrate the conceptual and technical potential of the project. With further financial support, by 2023 the DPI team aims to produce a full index of 193 countries as an annual ranking presented on a website and published as a report that visualizes the data and provides context for policymaking and academic audiences.
