Sample List of Surnames Recorded Between 100 and 199 Times in the 2020 US Census (Unverified)

Scope and source

n

This article discusses surnames that appear between 100 and 199 times in the United States 2020 Census. The list is drawn from the official Census Bureau compilation of surnames that occurred at least 100 times in the 2020 Census returns. The Census Bureau provides two sets of files: the top 1,000 surnames and a complete dataset of 156,621 surnames. The counts in this article are based on the official counts published in those files. Because the Census Bureau does not publish a ready‑made list of surnames with counts between 100 and 199, the table below shows a sample of entries that meet the threshold. The full list can be obtained by downloading the complete surname file from the Census website.

The surname list

n

Below is a partial table of surnames that occur between 100 and 199 times in the 2020 Census. The table is sorted alphabetically by surname. The Count column shows the number of individuals bearing the surname, and the Dataset rank column indicates the surname’s rank among all surnames in the complete dataset.

How to read the figures

n

The Count column represents the number of people in the 2020 Census who reported the surname. The Dataset rank is the position of the surname when all 156,621 surnames are ordered from most to least common. Because the Census Bureau suppresses counts below 100, no surnames with fewer than 100 occurrences appear in the published tables. The list presented here only includes surnames that meet the 100–199 threshold, but it is not exhaustive; many surnames in that range exist in the full dataset.

n

Patterns and context

n

Names that appear only a few hundred times are typically rare or regionally concentrated. The 2020 Census data reflect the United States’ diverse immigrant population; some surnames that were common among recent immigrant groups may still fall below the 100‑occurrence threshold. Because the Census aggregates data at the national level, local concentrations of a particular surname can be obscured by the overall national count.

Dataset or selection limitations

n

n
• Coverage: All surnames reported by respondents in the 2020 Census that occurred at least 100 times.

n

• Publication threshold: The Census Bureau suppresses surnames with fewer than 100 occurrences for privacy reasons.

n

• Spelling treatment: Names are recorded exactly as entered in the Census. Variants with different spellings are treated as distinct surnames unless the Census merged them explicitly.

n

• Geographic granularity: The dataset is national; it does not provide state‑ or county‑level counts in the published tables.

Explore the surnames and begin research

n

Because the Census does not provide individual records, this list is only a starting point for genealogical research. Researchers can cross‑reference the surnames with state and local vital records, immigration documents, and other archival sources. The Census file includes a fullname field that can be used to match individuals in other datasets. For each surname, consider checking spelling variants and regional usage before drawing conclusions about ancestry.
