Your collection, with the numbers intact

Choose one, two or all three facts. Birthday uses U.S. birth records from 2000–2014; first name uses the published baby-name records for your selected year; surname uses the 2010 U.S. Census surname tabulation. Each keeps its own comparison group on the image. These datasets do not link individual people, so there is no defensible combined “one in a billion” score.

The portrait export is 1080 × 1920 pixels for a story. The landscape export is 1200 × 630 pixels. Share card opens your device’s share sheet when it supports image files; otherwise it saves the image for you to attach yourself. The site does not post to any account for you. A card can include personal information, so choose only the facts you want to make public.

Your inputs are kept in the current page’s memory. Refreshing or closing the page clears the application’s state; no profile or server record is created. Read the methodology to understand what each comparison means, or the privacy page for hosting and analytics details.
