Baby names of 2010

Isabella and Jacob topped the lists in 2010, out of 3,696,271 births recorded across 31,664 different names. That is 3.3% fewer than the 2009 files hold. About 3.7 million of them are alive today.

Source: US Social Security Administration national baby-name files. Names given to fewer than five babies in a year are not published, so the totals here run below the true number of births. How far below is not the same in every year: the files hold 201,484 births for 1880 and 3,315,343 for 2025, so a change from one year to the next in the early decades is partly a change in what the record covers.
