亿 (yì) is the unit for 100,000,000, and it is used constantly for populations, money, and big statistics. Chinese counts large numbers in groups of four digits, so 一亿 (yí yì) is 10,000 万 (wàn). Example: 中国有十四亿人。(Zhōngguó yǒu shísì yì rén.) China has 1.4 billion people.
Common mistake: Learners often mix up 亿 (yì) with 亿-like 仡 or confuse it with 忆 (yì, to remember), which has the heart radical 忄 instead of 亻. Another common slip is translating 十亿 (shíyì) as "ten hundred million" and losing track of the fact that it means one billion.
