The world in data, set in Helvetica.

SPHRE is an independent, source-first data publication. Read global indicators as stories, compare countries, map change over time, and trace every figure to its source.

Data stories

• The Great Convergence — In 1960, where you were born decided how long you would live. Sixty years of data show that gap closing — unevenly, incompletely, but unmistakably.
• The Birth Dearth — From Seoul to Lagos, the same curve at different speeds: the global fertility decline is the quietest revolution in the data.
• The Wired World — Every country traces the same S-curve online — but the Global South skipped a century of infrastructure to get there.
• The Urban Century — In 1960 one person in three lived in a city. Today it is nearly three in five — the largest migration in human history, and it is not finished.
• The Great Slowdown — World population growth peaked above 2 percent a year in the 1960s. It has since fallen by more than half — the quiet unwinding of the twentieth century's loudest fear.
• The Age of Migration — Across the rich world, deaths now outnumber births. All the growth that remains arrives from somewhere else — and the data shows the handover happened years before the politics noticed.
• The Paired Ledgers of Refugee Geography — Origin counts and hosting counts describe different sides of displacement. Across many decades of first and latest observations, the countries carrying the greatest weight change with the measure.

The Brief

• Nigeria leads the African internet-use comparison; Kenya leads on mobile subscriptions — The latest World Bank readings distinguish population internet use from subscriptions per person as Mozambique prioritises digital infrastructure.
• Ukraine’s military expenditure was 34.5% of GDP in 2024 — Among five selected countries, Ukraine has the highest latest share—and the largest gap between its first and latest observations.
• Korea has the lowest latest fertility value in a four-country comparison — World Bank endpoints show lower fertility and a larger older-population share in Korea than at the start of the supplied record.
• India ranks above China at the latest population endpoint — World Bank indicators show a reversal in the two countries’ population ranking while distinguishing total size from annual growth.
• One inflation measure, sharply different scales — The latest annual observations place the United States and United Kingdom in the low single digits, Türkiye in the tens and Argentina in the hundreds.
• Internet use trails mobile subscriptions across three African countries — The latest World Bank observations show different internet-use and mobile-subscription rankings for Kenya, Nigeria and Ethiopia.
• Renewable power shares rose in three of five countries from 1990 to 2021 — World Bank endpoints show higher renewable shares for Germany, China and the United States, but lower shares for India and Brazil.
• Three in four people are online. The last quarter is the hard part. — Twenty years ago about one person in six used the internet; the S-curve has since climbed past 73 percent — and it is now visibly flattening at the top.
• Two-thirds of humanity now lives below replacement — The world's average fertility rate still clears the replacement bar — but the average conceals that most of the world's people already live under it.
• The world without power is down to one region — Since 2000 the number of people living without electricity has halved, to about 680 million — and nearly nine in ten of them now live in sub-Saharan Africa.
• Four million refugees went home last year — The world's refugee count has fallen for two years running, and 2025's drop was the steepest in the seventy-five-year record. The reasons run through Damascus, Kabul — and the limits of welcome in Tehran and Islamabad.
• The grid spent 13 years getting less green — Renewables' share of the world's electricity fell from 1990 to 2003 before wind and solar turned it around — the most underrated U-turn in the energy data.
