How We Measure Name Popularity
Namedary measures name popularity using historical birth records from the United States, United Kingdom, Canada, and Australia. The calculation gives greater weight to recent birth records while retaining information from earlier years, allowing popularity to reflect both current usage and longer-term presence in the available data.
Because the four countries differ substantially in population and birth volume, their records are evaluated separately rather than combined as raw counts. Each region receives a normalized popularity score based on the name's share of the available birth data, and names are then compared within that regional distribution.
The Five Popularity Levels
Each name with sufficient regional data is classified into one of five popularity levels using fixed percentile thresholds. These thresholds describe a name's relative position among other names in the same popularity distribution; they are not fixed quotas.
Level 5: Popular
Names at or above the 98th percentile. These names have the strongest observed popularity relative to other names in the dataset.
Level 4: Common
Names from the 90th to below the 98th percentile. They have a relatively strong presence in the available birth records.
Level 3: Uncommon
Names from the 70th to below the 90th percentile. They have a measurable presence in the data but rank below the more frequently observed names.
Level 2: Rare
Names from the 30th to below the 70th percentile. Their observed frequency is relatively low compared with names in the higher popularity levels.
Level 1: Extremely Rare
Names below the 30th percentile. These names have the lowest relative popularity among names included in the distribution.
Worldwide Popularity
Namedary's worldwide popularity is calculated from the regional results rather than from combined international birth counts. Each available regional percentile contributes equally to the worldwide score, so a larger country does not automatically have more influence on the result.
A region without an available name chart is excluded from the worldwide calculation. This means that missing regional data is not treated as evidence of zero popularity.
For a detailed explanation of the data sources, time-decay model, regional normalization, percentile calculation, and worldwide scoring, see our Name Popularity Methodology .
Namedary's popularity levels describe the relative statistical presence of a name in the available birth data, with recent records weighted more heavily and regional differences accounted for before producing the worldwide result.
