The thankful mother later named her daughter A’Miracle Natisha, middle name in honor of Lucas.

While about 85% of the babies accounted for were born to Finnish speakers, another 6% were born to Swedish speakers. Here are Finland’s top 10 girl names and top 10 boy names among Swedish speakers specifically:

Popular Baby Names in Luxembourg, 2015

According to the Luxemburger Wort newspaper, the most popular baby names in Luxembourg in 2015 were Emma and Matteo.

Here are Luxembourg’s top 5 girl names and top 5 boy names (maybe) of 2015:

Girl Names Boy Names
1. Emma
2. Julia
3. Marie
4. Lia
5. Charlotte
1. Matteo
2. (Theo?)
3. (Leo?)
4. (Louis?)
5. (Noah?)

I’m not sure about the boy names — the order was wasn’t explicitly stated. Here’s the quote:

For boys, the most commonly given name was Matteo. It seems that names ending in -eo were all the rage as Theo and Leo also experiencd [sic] considerable popularity.

Louis and Noah, the names of Grand Duke Henri’s two grandsons, continued to be popular among Luxembourg parents.

My source article also mentioned that “Portuguese, Chinese, Scandinavian and Irish-sounding names made a mark in Luxembourg with Jimao, Jia, Côme and Aidan making it into registers.”

In 2014, the top baby names in Luxembourg were Emma and Gabriel.

Popular Boy Names: Biblical vs. Non-Biblical

How has the ratio of Biblical names to non-Biblical names changed over time (if at all) among the most popular baby names in the U.S.?

This question popped into my head recently, so I thought I’d take a look at the data. We’ll do boy names today and girl names tomorrow.

First, let’s set some parameters. For these posts, “Biblical” names are personal names (belonging to either humans or archangels) mentioned in the Bible, plus all derivatives of these names, plus any other name with a specifically Biblical origin (e.g., Jordan, Sharon, Genesis). The “most popular” names are the top 20, and “over time” is the span of a century.

For boy names, the ratio of Biblical names to non-Biblical names has basically flipped over the last 100 years. Here’s a visual — Biblical names are in the yellow cells, non-Biblical names are in the green cells, and a borderline name (which I counted as non-Biblical) is in the orange cell:

Popular boy names: Biblical vs. non-Biblical, from Nancy's Baby Names.
Popular boy names over time: Biblical (yellow) vs. non-Biblical. Click to enlarge.
  • Biblical names: Adam, Alexander, Andrew, Austin (via Augustus), Benjamin, Daniel, David, Elijah, Ethan, Jack (via John), Jackson (via John), Jacob, James, Jason, John, Jonathan, Joseph, Joshua, Justin (via Justus), Lucas, Mark, Matthew, Michael, Nathan, Nicholas, Noah, Paul, Stephen, Steven, Thomas, Timothy, Zachary
  • Non-Biblical names: Aiden, Albert, Anthony, Arthur, Billy, Brandon, Brian, Charles, Christopher, Dennis, Donald, Dylan, Edward, Eric, Frank, Gary, George, Harold, Harry, Henry, Jayden, Jeffrey, Kenneth, Kevin, Larry, Liam, Logan, Louis, Mason, Raymond, Richard, Robert, Ronald, Ryan, Scott, Tyler, Walter, William
  • Borderline name: Jerry (can be based on the Biblical name Jeremy/Jeremiah or on the non-Biblical names Jerome, Gerald, Gerard)
    • It felt strange putting an overtly Christian name like Christopher in the non-Biblical category, but it doesn’t appear anywhere in the Bible, so…that’s where it goes.

      Here are the year-by-year tallies:

      Year Top 20 names
      given to…
      # Biblical # Non-Biblical
      1914 40% of baby boys 5 (25%) 15 (75%)
      1924 43% of baby boys 6 (30%) 14 (70%)
      1934 43% of baby boys 7 (35%) 13 (65%)
      1944 47% of baby boys 7 (35%) 13 (65%)
      1954 46% of baby boys 11 (55%) 9 (45%)
      1964 42% of baby boys 11 (55%) 9 (45%)
      1974 38% of baby boys 11 (55%) 9 (45%)
      1984 36% of baby boys 14 (70%) 6 (30%)
      1994 27% of baby boys 14 (70%) 6 (30%)
      2004 19% of baby boys 14 (70%) 6 (30%)
      2014 14% of baby boys 14 (70%) 6 (30%)

      But there’s a huge difference between sample sizes of 40% and 14%, so let’s also take a look at the 2014 top 100, which covers 42% of male births.

      By my count, last year’s top 100 boy names were half Biblical, half non-Biblical:

      Biblical names (49) Non-Biblical names (51)
      Noah, Jacob, Ethan, Michael, Alexander, James, Daniel, Elijah, Benjamin, Matthew, Jackson (via John), David, Lucas, Joseph, Andrew, Samuel, Gabriel, Joshua, John, Luke, Isaac, Caleb, Nathan, Jack (via John), Jonathan, Levi, Jaxon (via John), Julian (via Julius), Isaiah, Eli, Aaron, Thomas, Jordan, Jeremiah, Nicholas, Evan, Josiah, Austin (via Augustus), Jace (via Jason), Jason, Jose, Ian, Adam, Zachary, Jaxson (via John), Asher, Nathaniel, Justin (via Justus), Juan Liam, Mason, William, Logan, Aiden, Jayden, Anthony, Carter, Dylan, Christopher, Oliver, Henry, Sebastian, Owen, Ryan, Wyatt, Hunter, Christian, Landon, Charles, Connor, Cameron, Adrian, Gavin, Robert, Brayden, Grayson, Colton, Angel, Dominic, Kevin, Brandon, Tyler, Parker, Ayden, Chase, Hudson, Nolan, Easton, Blake, Cooper, Lincoln, Xavier, Bentley, Kayden, Carson, Brody, Ryder, Leo, Luis, Camden

      (Christian, Angel, Xavier, Dominic…all technically non-Biblical, despite having strong ties to Christianity.)

      50%-50% isn’t quite as extreme as 70%-30%, but it’s still noticeably more Biblical than 1914’s 25%-75%.

      Do any of these results surprise you?
