For your Monday morning: A map of most common name given to newborns by state over the last 60 years. One of the things that struck me is the way the visual shows the greater volatility of trends in girl names. Boy names slowly work back and forth across the country like a civil war battle line, while a new girl name frequently sweeps the country in one year. Both boy and girl names seem to become more trend driven over time.
One thing I've noticed while playing with most common name stats in the past: Names like TV channels have become more fragmented with time. A smaller percentage of babies are given the most common name now than thirty years ago (much less 100), and the percentage of babies accounted for by the 100 most common names has gone down over time.
