About these numbers

“Born” counts the babies of each sex given the name in 2009, from Social Security's records. “Alive today” estimates how many of them are still living, using SSA's cohort life tables for people born in 2009. “Avg. age, everyone” is the average age of everyone alive with the name, not just the 2009 babies. How we calculate this
