Read the number and the context

Choose between two numbers for questions about population, percentages and rates of change. Each question allows 20 seconds. A wrong answer or an expired timer ends the run; your score is the number of correct answers in a row.

Check the year, region and unit before choosing. The explanation and source after each answer help show why similar statistics can describe different things. At the end, you can submit a nickname to the weekly and all-time leaderboards.

Which version of a statistic counts as correct?

The year and definition in the question determine the answer. Survey dates and denominators can change a value, so check the explanation and original source when the answer is revealed.

Do friend challenges count toward the main leaderboard?

A friend challenge uses the same questions for a friendly score comparison. Since the answers can already be known, these runs do not enter the main leaderboard.
