Leon Falkner

Leon owns the numbers: how common each type is, the splits by gender, the score scales in our reports and every table that compares types. A frequency figure is only meaningful with its sample, its country and its year attached, and keeping those attached is his job.

He also checks the figures in everyone else's drafts, which is where most errors on a site like this would otherwise get through: a percentage taken from a different sample than the one cited, two sources blended into one table, or a rarity figure that has quietly lost a decimal place.
