173 of the 369 names beginning with N classify soft-sounding. As a proportion that is the highest of any letter in the catalogue, and it is not a quirk of the sample: N is a nasal consonant, there is no stop anywhere in it, and a name that opens on one tends to stay soft all the way through.
Nina, Nala, Nico, Nena, Niko
Look at the shape those share. Two syllables, a vowel between the consonants, an open ending. 108 of the letter ends in -a, which is a high share, and 246 of it is two beats.
Which makes it female-leaning, mildly
144 measure female against 112 male. Mild, because the same soft shape produces Nico and Niko as readily as Nina and Nala — the softness is in the consonant rather than in the gender of the names built on it.
The cost of having no edges
A name with no stop in it is a name with nothing to cut through noise, which matters if you expect to call it across open ground. That is the honest trade for the softness, and the letter's own answer to it is short: 121 of these are four letters or fewer, where at least the whole word arrives at once.

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.
