Global chicken consumption per person has roughly quadrupled since 1961. In that year, around two chickens were slaughtered per person worldwide each year. As many countries grew richer, demand for meat rose, and chicken became the cheapest and most widely eaten meat for many diets. Our World in Data uses this long series to show how a single food has expanded across the world over six decades. The pattern reflects economic growth, changing diets and the efficiency of modern poultry production.

Hampi is a UNESCO World Heritage Site in Karnataka, India, with more than 1,600 surviving remains spread over 4,100 hectares. It was the capital of the Vijayanagara Empire from 1336 to 1565. Travellers from Persia and Portugal described it as a prosperous, wealthy and grand city with temples, markets and farms along the Tungabhadra River. By 1500 it was estimated to be the world's second-largest city after Beijing, and probably India's richest at the time. In 1565 a coalition of Muslim sultanates defeated the Vijayanagara Empire, its capital was conquered and destroyed, and the city was left in ruins. Hampi remains a religious centre, with the active Virupaksha Temple at its heart.
