Jason peaked in 1977 at rank 2 and has spent the nearly fifty years since drifting downward to its current position of 148. Over a million American boys have been named Jason. Almost no other boys' name has reached the top 5 and then so completely lost its chart relevance — the slide is one of the longest sustained declines in the SSA database, and it tells a generational story about how 1970s naming has become permanently coded as a specific era.
The Greek mythological hero
Jason comes from the Greek Iason, traditionally derived from the verb iasthai ("to heal"). The name belongs to Jason of Greek mythology, leader of the Argonauts and the questing hero who retrieved the Golden Fleece. The myth has been continuously read and adapted across European cultures for over two and a half millennia, giving the name one of the deepest mythological footprints of any active English-language name.
The Christian-era usage runs through the Greek New Testament, where Jason of Thessalonica appears in Acts 17 as a host of Paul during his second missionary journey. That biblical mention gave the name a soft Christian register layered onto the pagan mythological one, which helped the name persist through European Christian centuries.
The 1977 peak in cultural context
The 1970s peak coincides with a broader American moment. A generational shift away from the heavily Catholic and biblical names that had dominated the 1950s and early 1960s. Jason, Michael, Jennifer, and Christopher all rose together in that window, replacing Robert, Mary, John, and David in the top 10. The Friday the 13th film franchise (Jason Voorhees, debuting 1980) added a horror-coded layer that arrived just after the peak and has dominated the name's adult-American cultural memory for the past four decades.
From a data read, Jason's slide is one of the cleanest examples of a peaked name working through its full life cycle. The chart shape, top 5 in the late 1970s, top 30 by 2000, mid-100s by 2024, is the trajectory of a name that became permanently tied to its peak generation rather than carrying forward.
The counter-reading
The honest concern with Jason is that the name is now firmly 1970s and 1980s coded. A child named Jason in 2025 will share the name with their father's generation, which can produce a slightly older-sounding register. The Friday the 13th association lingers for older Americans but is fading for younger parents. Common pairings favour traditional middles: Jason Michael, Jason Robert. The 1970s data shows Jason's original peak context.
