How Datastory's data visualizations help the Tax Justice Network to expose global tax havens

Datastory built a website for the Tax Justice Network to host the Corporate Tax Haven Index (CTHI), an innovative platform that visualizes how countries enable corporate tax avoidance. With interactive features, dynamic rankings, and multilingual support, the site provides clear insights into global tax abuse, helping policymakers and advocates push for tax reform.

Challenge

The Tax Justice Network faced the challenge of processing a multi-layered dataset covering 70 countries, 18 indicators, and over 70 unique IDs, to reveal global trends in corporate tax avoidance. The difficulty was not only in analyzing this vast amount of data but also in presenting it in a way that could be easily understood by policymakers, journalists, and the public. The team needed a tool that could present historical data, policy analysis, and financial metrics through a clear and engaging interface.

Solution

In response, Datastory built the Corporate Tax Haven Index website for the Tax Justice Network. It is a groundbreaking platform designed to bring clarity to the world of corporate tax abuse. With interactive country profiles, dynamic charts ranking countries by their Haven Score and Global Scale Weight, and a timeline-enabled bar chart tracking changes in tax rankings over time, the CTHI provides users with both historical context and real-time insights. The tool’s multilingual accessibility ensures that it serves a truly global audience, while its commitment to transparency, including regular updates, keeps the data relevant and actionable for users.

Result

The CTHI is aiming to become a vital resource in the fight against corporate tax abuse, empowering decision-makers with timely, data-driven insights. By making the mechanisms behind tax avoidance visible, the Index drives accountability and supports policy reform. Frequent updates ensure that the data stays current and relevant, and the tool’s accessibility fosters global engagement in tax justice efforts.
