Origin
The surname Alger is believed to have originated in England during the medieval period. It is derived from the Old English words "ald" meaning "old" and "gara" meaning "triangular piece of land." This suggests that the name likely referred to someone who lived on or near an old triangular-shaped piece of land or field.
The earliest recorded instances of the name Alger can be found in various medieval records and manuscripts. In the Domesday Book of 1086, a record of landowners in England commissioned by William the Conqueror, there are several entries for individuals with the surname Alger or similar variations like Algere and Algare.
One notable early bearer of the name was Sir William Alger, a knight who fought alongside King Richard I in the Third Crusade during the late 12th century. Another was John Alger, a prominent merchant and alderman in the city of London who lived in the 14th century.
The surname Alger also has connections to various place names in England, such as Algar's Farm in Wiltshire and Alger's Hill in Dorset. These place names likely derived from individuals with the surname Alger who lived or owned land in those areas.
In the 16th century, the name Alger was associated with the Puritan movement in England. One notable figure was Thomas Alger, a Puritan minister who was born in 1616 and later emigrated to New England in the 1630s, settling in Massachusetts.
Another significant bearer of the name was Horatio Alger Jr. (1832-1899), an American novelist and writer famous for his popular juvenile fiction stories depicting young boys overcoming adversity and achieving success through hard work and perseverance.
Other notable individuals with the surname Alger include Russell Alger (1836-1907), an American politician and businessman who served as the 20th United States Secretary of War under President William McKinley, and Philip Alger (1892-1967), an American diplomat and author who served as the United States Ambassador to Belgium and Pakistan.
Demographics
Among Census respondents with the surname Alger, the largest self-reported group is White at 89.3%. The next largest groups are Hispanic (3.9%) and Two or More Races (3.8%).
The bar chart below shows how Alger bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Alger surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
