The popularity (frequency) distribution of given names typically follows a power law distribution.

Since about 1800 in England and Wales and in the U.S., the popularity distribution of given names has been shifting so that the most popular names are losing popularity. For example, in England and Wales, the most popular female and male names given to babies born in 1800 were Mary and John, with 24% of female babies and 22% of male babies receiving those names, respectively. In contrast, the corresponding statistics for in England and Wales in 1994 were Emily and James, with 3% and 4% of names, respectively. Not only have Mary and John gone out of favor in the English speaking world, also the overall distribution of names has changed significantly over the last 100 years for females, but not for males. This has led to an increasing amount of diversity for female names.
