Origin
The surname Lema has its origins in Spain and the Basque region. It is believed to be derived from the Basque word "lema", which means "summit" or "peak". This suggests that the name may have initially been a topographic name, given to someone who lived near a prominent hill or mountain.
The earliest recorded instances of the Lema surname date back to the 15th century in the Basque provinces of Spain. One notable example is Rodrigo Lema, a merchant from Vizcaya who was mentioned in local records from the year 1482. The name also appears in the census records of the town of Lekeitio in 1511, where several Lema families were documented.
During the 16th and 17th centuries, as the Spanish Empire expanded across the Americas, some individuals bearing the Lema surname migrated to the New World. One such individual was Juan Lema, a Spanish soldier who participated in the conquest of Peru under Francisco Pizarro in the 1530s.
In the 18th century, the Lema surname can be found in various parts of Spain, particularly in the Basque region and the neighboring provinces. One notable bearer of the name was Ignacio Lema, a Basque philosopher and theologian who lived from 1712 to 1785 and authored several works on ethics and moral philosophy.
As the Lema surname spread beyond its Basque origins, it also took on variations in spelling, such as Lema, Lemas, and Lemma. One prominent individual with the latter spelling was Carl Samuel Lemma, a Swedish botanist and explorer who lived from 1785 to 1849 and made significant contributions to the study of plant life in South America.
Other notable individuals with the Lema surname include Manuel Lema, a Spanish military officer who fought in the Napoleonic Wars and was awarded the Order of Santiago in 1815, and Juana Lema, a 19th-century Ecuadorian poet and activist who campaigned for women's rights and education in her home country.
Demographics
Among Census respondents with the surname Lema, the largest self-reported group is Hispanic at 66.2%. The next largest groups are White (21.3%) and Black (9.8%).
The bar chart below shows how Lema 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 Lema surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Lema (2000, 2010, 2020).
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.
