The Most Popular Baby Names by Decade

Picking a baby name can be tough. Modern or traditional? Family name or an entirely new creation? In the United States, parents are free to name their new addition whatever they please, unlike countries that regulate baby names, like Germany, New Zealand, and Sweden. But even with that freedom comes the possibility you’ll share your so-called unique name with thousands — or millions — of other people.

If you’ve ever wondered how popular your name is, it’s easy to find out. In 1998, the Social Security Administration began ranking the top 1,000 most common first names submitted on Social Security card applications for each year dating back to 1880. The administration then whittled down the list to the 200 most popular names of each decade, tallying up how many people share the same identifier. That list has become a tool for parents-to-be looking for the perfect name, and a warning for those trying to avoid name trends. Here are the most popular boy and girl names from the past 11 decades.

Top Girl Names: Mary, Helen, Dorothy, Margaret, Ruth

The early years of the 20th century were all about innovation. Homes were slowly becoming equipped with electricity and telephones, and automobiles became more accessible to the average American. But when it came to naming a new generation of babies, traditional monikers held tight. It’s not surprising that “classic” names such as William and Ruth were top contenders — in a relatively young country where new parents still held tight to their ancestral traditions, it was common to recycle names to connect children with their heritage. Families tracing their roots to the British Isles, for example, would follow set patterns that named babies after grandparents, uncles, and aunts based on birth order.

Boy names remained relatively traditional and Eurocentric during the 1920s. William and Charles gave off strong, regal impressions, which is no surprise considering their origins — both have Germanic roots and were used abundantly among British, French, and Spanish monarchs. While girl names were similar to the prior decade, newcomer Betty was less formal than its original form of Elizabeth during a decade where women sought financial and social independence (but still not as zany as flapper-inspired names such as Fern and Iola).

Top Boy Names: Robert, James, John, William, Richard

Top Girl Names: Mary, Betty, Barbara, Shirley, Patricia

Seemingly out of nowhere, the name Patricia catapulted to the country’s top-five spot for girl names, when just 10 years prior it ranked 104. But why? It’s possible an influx of Irish immigrants in the early 20th century helped popularize the name. As a feminine form of Patrick — Ireland’s patron saint — Patricia seems traditionally Irish, though a survey of Irish Americans suggests it’s more commonly used in the U.S. than in the Emerald Isle itself. It’s likely a name that bridged the gap between heritage and new homeland, helping young Irish Americans hold onto their family history while blending into American culture with an easy-to-pronounce name. Patricia remained a top-five name throughout the 1950s, spawning shortened names such as Trish, Patti, and Tricia as its popularity waned.


Top Boy Names: James, Robert, John, William, Richard

Top Girl Names: Mary, Linda, Barbara, Patricia, Carol

Traditional names like Richard and James continued to reign supreme for boys born in the 1940s; with an ongoing war, it’s likely parents reused family names to honor loved ones stationed overseas. New names for girls, however, emerged, with Carol becoming a trendy alternative to the longer Caroline. Often given to wintertime babies, Carol was considered an uplifting holiday name that honored the season’s musical hymns. It peaked during the 1940s and fell from the top-10 list by 1951. Equally prominent Barbara, which became common in the 1800s, also fell out of style by the early ‘50s, but ranks overall as the sixth-most popular name for a girl over the last century, with 1.3 million women sharing the name.

Top Boy Names: James, Michael, Robert, John, David

Top Girl Names: Mary, Linda, Patricia, Susan, Deborah

The 1950s marked a shift in Mary’s role as the top girl name of all time, ending a run that had dominated the name leaderboards since the 1880s — the Social Security Administration’s oldest data. It’s no surprise considering the name means “beloved” and is an ode to the Virgin Mary. History has no shortage of famed Marys, ranging from queens and actresses to fictional characters like Mary Poppins. While less common now (holding spot 124 in 2020), similar names have carried on, such as Maria and Mariah. From 1921 to 2020, more than 3.1 million babies in the U.S. shared the simple, four-letter name.


Top Boy Names: Michael, David, John, James, Robert

Top Girl Names: Lisa, Mary, Susan, Karen, Kimberly

Leonardo da Vinci’s most famous painting may have spurred a name trend during the 1960s. The Mona Lisa made its first trip to the U.S. in 1963, displayed at the National Gallery of Art in Washington, D.C., and created social excitement that led 2 million spectators to view the portrait. While the name Lisa had reached the number one spot a year before the painting’s tour, it held firm for seven more years until being dethroned in 1970. The ‘60s also ceded some traditional boy names for more modern styles, with Michael starting its run as the top boy name for decades to come.

Top Boy Names: Michael, Christopher, Jason, David, James

Top Girl Names: Jennifer, Amy, Melissa, Michelle, Kimberly

The 1970s brought about a major shift in common boy names. With Richard and William becoming “old-fashioned,” parents opted for the ever-popular Michael and David. But one name ascended in a way few other names have: Jason. The name shot up the charts from spot 87 in the 1960s to third place in the 1970s. While sounding modern, Jason actually has Greek origins; in mythology, heroic Jason embarks on an epic quest to restore his family to his homeland’s throne. The name fad quickly dissipated, dropping down to the 11th-most popular spot in the 1980s and further in the ‘90s, but it has echoes in 2010’s Jaxon and Jaxson.

Top Girl Names: Jessica, Jennifer, Amanda, Ashley, Sarah

Christopher wasn’t a new name in the 1980s — it has Latin and Greek origins, becoming common among Christian followers during the Middle Ages in honor of a 3rd-century saint who protected travelers. It’s unclear why Christopher reached such heights in the ‘80s, though it could have been influenced by the number of Christophers on stage and screen; actors Christopher Reeve, Christopher Walken, and Christopher Lloyd got their big breaks in the late ‘70s. For girls, names like Jessica and Sarah maintained peak popularity until the early 2000s, around the same time parents began seeking out more unique names.

Top Boy Names: Michael, Christopher, Matthew, Joshua, Jacob

Top Girl Names: Jessica, Ashley, Emily, Sarah, Samantha

The name Michael was the highest-ranking boy name for five short years — 1954 to 1959 — only to come roaring back in 1961 and then holding the No. 1 spot through the 1990s. Its Hebrew origins refer to the sword-wielding archangel Michael, at one time making it a common name among soldiers and military families. In its last decade of acclaim, the name was boosted by a number of celebrities: singers Michael Jackson and Michael Bolton, basketball great Michael Jordan, and actors Michael Keaton and Michael J. Fox. In 2020, Michael remained the 12th most popular name and was the moniker given to 4.3 million boys since 1921.

Top Girl Names: Emily, Madison, Emma, Olivia, Hannah

New millennium, new names ... right? Not so much. The top names of the 2000s — while seemingly fresh compared to years of Jennifers, Lisas, and Williams — mostly have old roots. The popular boy names have biblical ties, along with Hannah and Olivia (which refers to the symbolic olive tree). Madison, traditionally a boy name, was commonplace throughout the 1800s. Just 100 years prior, Emma was the 13th most popular name in 1900, ranking low on baby name charts until the early 2000s.

Top Boy Names: Noah, Liam, Jacob, William, Mason

Top Girl Names: Emma, Olivia, Sophia, Isabella, Ava

Just like decades before, naming trends don’t often disappear easily — and it’s evident with names like Emma, Olivia, and Sophia hanging on for a second decade. Compared to popular names 100 years before, modern names feel like a complete departure from the Eurocentric names of 1910, and that’s because naming websites and social media provide access to more diverse names than ever before. Where some parents look to trend-free, steadfast names (such as William), others consider unique monikers that help their kids stand out in a world of Isabellas (consider Athena, ranked at 173).

It’s hard to guess what names are likely to pop up on the Social Security Administration’s 2020 rankings. While new baby name trends are emerging — specifically nature-based names, like August and Sage, and gender-neutral names, like Charlie and Blake — there’s no clear science as to why some names become standouts while others languish for decades. Some linguists and naming experts theorize that times of social change and upheaval spawn new, creative names. If that’s the case, 2020’s top picks may be the most unique we’ve seen in a while.
