Biblical Names Are the Most Stable Category in the Data
Across 145 years of records, biblical names behave differently from every other group. Here is what that looks like.

If you sort names by how little their popularity moves over a century, biblical names dominate the top of that list. This is the clearest structural pattern in the whole dataset, and it is worth understanding whether or not the religious association matters to you.
Stability, not popularity
The claim is not that biblical names are the most popular — several are, but many are not. The claim is that they move less. Fashion-driven names show tall, narrow curves. Biblical names show broad plateaus that persist across generations that had nothing else in common.
The mechanism is straightforward. A name whose popularity depends on fashion falls when the fashion changes. A name anchored to a text that does not change has a floor under it.
The categories are not equivalent
The data distinguishes biblical people, places and divine titles, and they behave quite differently. Names of people are by far the largest group and the most stable. Place names are a much smaller group and behave more like ordinary fashion names — they get adopted because they sound good, and they move accordingly.
Practical reading
- If you want a name that will not date your child, the biblical-person category is the most reliable place to look, independent of belief.
- If you want something less common, look at biblical names outside the familiar top tier. The category is far larger than the handful of names that dominate it.
- Do not assume a biblical name is a safe choice for being uncommon. Some of the most-given names in the entire record are in this category.
The biblical names list shows the category ordered by total births, and each name page states which sub-category it falls into.
