Babies given each name, 1880–2025
Sid Siddhartha
Each line is every baby given the name that year, girls and boys added together — the only count that means the same thing for both names. A line breaks where the name fell below five babies in a year — the point at which the SSA stops publishing it — rather than being drawn through a figure nobody published. A single published year in a gap shows as a dot.
Who was ahead
Of the 144 years in which either name was published, Sid for 134 years and Siddhartha for 10 years. The lead changed hands 11 times.

A rank is a position within one sex’s list for one year, so the two rank rows are not subtracted from one another and the winning column is not marked on them. The living figure is a life-table estimate, not a count.
Which name is older
Half of the Sids alive today are over 53; half the Siddharthas are over 15. That is 38 years between them: two names in use at the same time, worn by two different generations.

Both names abroad
Countries whose statistics office publishes both names, so the comparison can be made somewhere other than the United States.
| Country | Sid | Siddhartha |
|---|---|---|
| England and Wales | 745 | 78 |
Every spelling a country files separately is added together, over whatever years that country publishes — which is not the same range in any two of them, so read the columns against each other and not the rows.
