Zeus. Zeke. Zoe. Zane. Z is a small letter — 210 names — carrying an unusually high share of monosyllables: 50 of them, which for a letter this size is more than any of its neighbours manage. Short is the whole character of it.
The sound does the work
A Z is a voiced sibilant: it buzzes, and a buzz cuts through a room in a way an S hiss does not quite manage. Combine that with one syllable and you have about the most audible name shape available in English, which is a reasonable explanation for why Zeus is one of the most registered names in the whole catalogue.
Short at both ends
92 of the letter is four letters or fewer and only 27 run to three syllables or more. There is almost no long vocabulary here — Zachary and Zeppelin are the exceptions, and both get shortened on arrival.
Evenly split, and full of -a
69 measure male against 64 female, close to level, and 60 end in -a — Zelda, Zara, Zia. The letter manages to be blunt and open at the same time, which not many can.

Every count on this site is a tally of real registrations: pet licences and shelter intakes published as open data by New York, Seattle, Austin, Montgomery County, Cambridge, Zurich, Basel and four Australian councils. Popularity here is the average share a name holds across those registers, so a name common in a small city is not buried by one common in a large one. Five of the eleven registers are North American and they supply 86% of the records, so read the ordering as naming in those places rather than worldwide.
