Off By

Five numerical questions a day about everyday economics and society, drawn mostly from US sources such as BLS, the Federal Reserve, USDA and Pew Research. Answers are set with a slider or typed, each is scored by how far off it was as a percentage of the possible range, and the average becomes the score.
