Vintage Baby Names

The hundred-year rule, and why old names come back

Names run on roughly a century-long cycle, and the pattern is consistent enough that demographers have a name for it. A name peaks, declines over about forty years, spends a few decades sounding dated, becomes associated with the very elderly, and then — once no living child bears it and the association is with great-grandparents rather than parents — becomes available again. That is why the vintage names charting now are the names of the 1900s to 1920s, not the 1970s.

You can see it in what has returned. Hazel, Ruth, Ada, Iris, Alice, Nora, Theodore, Arthur, Henry, Ezra and Silas were all common a hundred years ago, disappeared almost entirely by mid-century, and are now rising. Meanwhile the genuinely dated-sounding names today — Karen, Gary, Debra, Barry, Susan — are the mid-century peaks, and they are simply not old enough yet.

There are exceptions, and they are informative. Names that get attached to a single dominant cultural figure often skip the cycle entirely. Names with strong occupational or class associations sometimes return early. And names that were never common in the first place — the genuinely rare ones — do not follow the cycle at all, because there is no peak to recover from.

If you like this register, one practical route is to look at a census or birth record from the 1910s in your own family's country rather than at a modern vintage list. You will find names that have not yet been picked up by the revival, which is most of them: for every Hazel that has come back there are a dozen contemporaries that have not. The other route is to work from nicknames — many of the most usable vintage names today, like Theo, Nell, Sadie and Gus, entered modern use as short forms first.
