My favorite names!

Olivia, a lovely Shakespearean name with an admirable balance of strength and femininity, is the Number 1 name for baby girls in the US and one of the top girls' names around the world.

Hazel has a pleasantly hazy, brownish-green-eyed, old-fashioned image that more and more parents are choosing to share. Former Old Lady name Hazel reentered the popularity lists in 1998 and now is near the top of the charts.

Ava is one of the prime examples of a modern classic name, rising thought the course of a generation into the Top 10, where it has lingered for nearly 20 years.

Jasper originated as a variation of the Latin Gaspar, which ultimately derived from the Persian word ganzabara, meaning "bringer of treasure." As a given name, Jasper’s etymology is unrelated to that of the gemstone, which comes from a Semitic word meaning "speckled stone." Jasper is the usual English form for one of the Three Wise Men who brought gifts to the infant Christ according to medieval tradition and appears in the Bible as a reference to the stone itself in Revelations 4:3.

Liam is the top boys' name in the US, holding the Number One spot for the past eight years and also ranking as one of the most popular boys' names around the western world.

Penelope is an unlikely 21st century baby name success story. Off the Top 1000 for 25 years, Penelope jumped back on in 2001 and has been heading uphill ever since, propelled by the trend for mythological names, Spanish actress Penelope Cruz, and some high-profile celebrity babies.

Mia is an appealingly unfussy multicultural name that has enjoyed a meteoric rise up the charts and is now firmly among the ten top girl names. Mia has surpassed its mother name Maria as the Number 1 girls' name starting with M.

Wyatt has been hot, which is to say cool, for several years now. With its easy Wyatt Earpish cowboy charm, it's relaxed but still highly respectable.

Eliza is a name with a wonderful combination of streamlined zest and Eliza Doolittle charm and spunk. It's a classic that's popular right now -- but not too popular.

Elena is at its most popular point ever in the US, thanks to its cross-cultural appeal and the overall popularity of El- names. It's more international than Ellen or Eleanor, but still accessible.

Levi, lighter and more energetic than most biblical names, with its up vowel ending, combines Old Testament gravitas with the casual flair associated with Levi Strauss jeans.

John reigned as the most popular of all boys' Christian names for 400 years, from the time the first Crusaders carried it back to Britain until the 1950s. Then American baby namers finally seemed to tire of this straight-arrow, almost anonymous John Doe of names, replacing it with fancier forms like Jonathan and the imported Sean and Ian.

Luke is a cool-yet-strong Biblical name with a relaxed cowboy feel, which has been on the rise since the advent of Luke Skywalker.

Sadie started as a nickname for Sarah, but their images couldn't be more disparate. Where Sarah is serious and sweet, Sadie is full of sass and fun.

Max was derived from Maximilian, a Latin name that originated from the Roman family name Maximus. The character name Max in the children's classic Where the Wild Things Are had an impact on baby namers. Max is a widely used name internationally.

With its sharp, succinct sounds and cool, laidback style, Eli is a popular choice among parents today. Compact and punchy, it is a Biblical name with plenty of charm.

The Reid spelling is the most popular by half, probably because it feels more like a name than Reed, which looks more like a word. It's used occasionally for girls but this name is firmly in the boys' camp.

Aaron is a name of subtle contrasts: an unusual spelling that is easily recognizable; a solid Biblical choice that doesn’t feel exclusively tied to religion; a well-established name for boys but sometimes confused with the girls’ name, Erin; used internationally but with notably different pronunciations; classic like Andrew but not out of place with recent favorites like Weston or Jayden.

Riley—an upbeat, friendly surname name—is red hot for girls and still going strong for boys. If you haven't been spending much time around babies recently, you may be surprised to learn that Riley is the most popular girls' name starting with R and also the Number 1 Irish name for girls in the US.

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.
