The influence of Christianity has declined in the United States. Yet in maternity wards across the country, when newborns scrunch up their tiny faces and fill their lungs with their first breaths of air, parents regularly turn to Scripture. They give their children biblical names.

Some Bible names are more popular than ever. One hundred years ago, for example, Noah was the 400th most common newborn name in America. But in the early 1990s, the number of babies named after the ark-building patriarch rose rapidly. By 1996, Noah was the 50th most popular baby name for boys, and by 2009, it was in the top 10. For the past decade, Noah has been the No. 1 or No. 2 name for boys.

A few names, such as Mary and Martha, have become less popular, but other Bible names appear resistant to cultural change. A girl born in America today is about as likely to be named Elizabeth as she would have been a century ago. David was the 28th most popular boy name in 1920. It was 25th in 2020. Other popular names include Eden, Grace, Elijah, and John.

America has changed a lot in 100 years. But when it comes to naming babies, plenty of people still go back to the Bible.
