Jackson is one of those names that's much more popular than you think, coming in near the top of our annual Playground Analysis, which ranks names by grouping all their spellings together. Last year, more than 13,000 baby boys were named Jackson -- along Jaxon, Jaxson, Jaxxon, Jaxen, Jaxyn, Jaxsen, and Jaxsyn -- which counted together makes it the Number 5 boys' name.

Jaxon has been mostly climbing in popularity since it entered the Top 1000 in 1997, proving that many parents have decided to rev up the cool factor of Jackson by giving it this streamlined spelling. (Though we still prefer the original.)

No, Jackson is not the latest crazy name the girls are stealing from the boys. Oddly enough, Jackson was given to MORE girls a decade ago than it was last year, probably as a family name or as a tribute to the musicians. But Jackson's extreme popularity as a boys' name has probably made it feel less possible for girls.

One of several phonetic spellings of Jackson moving up the charts, Jaxson entered the Top 100 in 2013 and has remained there since. It's also picking up steam in England and Wales.. Actor Eric Mabius used it as his son Rylan's middle name.

There are seemingly infinite ways to spell Jackson — in fact, if you add all of them up, it becomes the most popular boy name in America. Jaxsyn is mid-to-low range popularity among all the variations.
