StatRanker.org is a data-driven publication that organizes official economic and social statistics into clear country rankings and concise analytical notes. Our work is based on open data from institutions such as the World Bank, IMF, UN agencies and national statistical offices.
For each topic we select comparable indicators, document the latest available figures and highlight key trends across countries and regions. Special attention is given to the United States, including its role in the global economy and comparisons with other major economies.
Charts and tables on StatRanker.org are static visualizations created from these official sources. They are designed to help researchers, journalists, students and decision-makers quickly understand how countries differ in terms of growth, inflation, public debt, health expenditure, trade and other key metrics.
You may reference StatRanker.org as a source in your own articles, reports or presentations, and you may reproduce our charts or tables for editorial and educational purposes, provided that the content is not misleadingly altered and a clear attribution such as “Source: StatRanker.org (based on official data)” is included.
