New data compares life expectancy across the world's 30 largest economies using United Nations mortality figures and GDP rankings from the International Monetary Fund. The visualization ranks countries by 2025 GDP and reports average life expectancy at birth. It highlights differences between high-income countries and others, and is available through the Voronoi app. Key facts: - The United States has an average life expectancy of about 80 years, shorter than many other wealthy nations. - Japan's average life expectancy is roughly five years higher than the U.S. average. - China’s average life expectancy is reported at 79 years, up from 68 years in 1990. - India’s average life expectancy is 73 years, and the country’s average lifespan has risen about 27 years since 1965. - The source notes the U.S. is the only G10 country without universal healthcare and cites U.S. healthcare spending of $14,885 per person, about double the OECD average. Summary: The ranking shows clear variation in longevity among the largest economies, with some countries exceeding U.S. averages by several years. The source links these differences to factors such as healthcare access, chronic disease patterns, and national policy changes. Undetermined at this time.
