Official data sources
England and Wales results use published Office for National Statistics name records. United States results use published Social Security Administration name records. The searchable period is 1996–2025 where a published value is present in the imported source data.
Because ONS coverage is England and Wales, the site does not label those figures as whole-UK statistics.
What the rarity label means
The rarity label is a plain-language description of the latest known published birth count for the selected dataset and exact spelling. Current working bands are:
- Exceptionally rare: fewer than 5 published records
- Very rare: 5–19
- Rare: 20–99
- Uncommon: 100–499
- Familiar: 500–1,999
- Popular: 2,000–9,999
- Very popular: 10,000 or more
These are descriptive site categories, not labels published by ONS or SSA. They should be read alongside rank and country context.
Female and male record categories
The official source records are divided into female and male categories. The combined view adds known published counts where appropriate, but it never adds or averages official ranks. Ranks remain attached to their original category.
The categories describe how the historical data was published. They are not an assumption about the identity of anyone who uses the name today.
Rising, falling or steady
The recent trend examines up to the latest five usable published observations. It compares movement across the period rather than reacting to a single one-year jump. At least three usable points are required.
- Trending upwards: sustained average annual growth of approximately 4% or more.
- Trending downwards: sustained average annual decline of approximately 4% or more.
- Holding fairly steady: movement remains between those thresholds.
- Not enough published data: fewer than three usable observations.
Redacted, omitted and missing figures
A redacted value is not treated as zero. Nor is an absent row. Official publishers can suppress or omit very small figures for privacy and disclosure-control reasons.
“No published result” means exactly that. It does not prove that nobody received the name.
Comparing countries
Raw birth counts are displayed for transparency, but they are not presented as a population-adjusted comparison. The United States has a much larger population than England and Wales. Official ranks are therefore shown beside counts wherever possible.
Exact spellings are compared with exact spellings. Ariana and Arianna have separate histories.
Corrections and questions
If a result appears inconsistent with an official publication, please send the details, including the name, country, record category and year.
