If you look at the graph you can see how with age of how old the females are the names are outdated.  Dorothy, Carol, Ruth and a lot f the bottom names are names that are grandparents would have of older relatives.  You don't see many women these days walking around with the name Barbara or Frances.  When you look at the top of the chart you see names that we hear more than once a day and we have multiple friends with that name such as Sarah and Emily which are more youthful names.  You don't hear of many older people with the name Ashley now do you?  I just find it interesting how as the years go on we try to have more youthful sounding names.  I'm interested and a little worried to see what names people will come up with next because you are already hearing people naming their kids after fruits and colors.  Hopefully generations to come wont go to crazy with the creativity they use to name their children.
