What does Thiago mean?
Wiktionary, Portuguese section
Thiago is “alternative spelling of Tiago; a male given name, equivalent to English James” Its etymology gives the sense “natal, relating to birth” (nātālis).
The th in this variant spelling was added unetymologically; compare Nathália, a variant spelling of Natália, where a similar unetymological th was added, despite the name coming from nātālis (“natal, relating to birth”).

An estimate, not a count. SSA’s files count people born in the United States who received a Social Security number, so anyone born abroad is not in them; before 1937 most people got a number as adults, and their survival is counted from that age.
Living estimate: SSA births carried forward with the survival rates in SSA’s cohort life tables (2024 Trustees Report) for each birth year and sex. How the estimate is made. Count: Census Bureau, first names in the 2020 Census (released April 14, 2026; names reported 100 or more times, with the Bureau’s disclosure-avoidance adjustment).

Where Thiago is more common than its national share predicts
Relative to its national share, Thiago is most over-represented in Florida: since 1986 it was given 2.2 times as often there as its national share each year would predict.
States: SSA state file, 1910-2025, published May 8, 2026; births count girls and boys together, and the rank is among boys’ names in the state in 2025. The file leaves out any state and year with fewer than 5 babies of the name, so small states are undercounted; each ratio compares the state’s births of Thiago with the births its national share predicts year by year, for states with at least 100 births of the name.
