The Most Popular Baby Name Every Year of the Last Century

History Facts

Over the past hundred years, baby-naming trends have largely been shaped by family traditions and popular culture. Classic names such as Mary, John, Betty, and James often appear repeatedly in family trees, passed down out of respect for previous generations and a desire to keep family legacies alive. By the latter half of the 20th century, parents found baby name inspiration in popular culture, including films, theater, and music. The name Jennifer, for instance, began its climb in the U.S. thanks to the George Bernard Shaw play The Doctor’s Dilemma, which debuted on Broadway in 1927. Today, Olivia and Liam are the reigning favorites, and it’s likely only a matter of time before names that are already in the top 10 — such as Mia, Mateo, Evelyn, and Elijah — claim the No. 1 spots.Here is a fascinating look at the most popular girls’ and boys’ names of the last century, based on data collected by the U.S. Social Security Administration from Social Security card applications.

The “Roaring ’20s” brought new cultural, economic, and sexual freedoms for women, but the most popular female names of the Greatest Generation — those born between 1901 and 1927 — didn’t reflect this newfound sense of liberation. Mary remained the most popular girls’ name from 1924 to 1929, just as it had since 1900. A biblical name that appears in both the Old and New Testaments, Mary is the anglicized form of Maria and originated from the Hebrew Miryam. In 1924, the name Robert, favored by European royalty and nobility in the Middle Ages,” replaced John, another common biblical name, as the most popular boys’ name, ending John’s decades-long place at the top of the list.
