Michael Williams points to the change in popularity of the name Hillary. See his post for a cool graphic, but here's the table from the Social Security Administration:

Year of birth	Rank [lower = more popular]
2005	882
2004	809
2003	[>1000]
2002	[>1000]
2001	886
2000	878
1999	856
1998	868
1997	725
1996	693
1995	684
1994	566
1993	261
1992	131
1991	165

George has remained roughly stable from 2000 on; William spiked in 1998, of all years, and remained high (now #11, as opposed to $20 in 1992).

Eugene has been declining ever since this blog was founded in 2002. On the other hand, it has been declining since 1991, the first year that this table reports, and even more since the 1930s. In the 1930s, by the way, it was #25 (owing at least in part, I'm told, to the fame of Socialist Eugene V. Debs); in 2005, it was #539.

But, hey, I beat Hillary!

UPDATE: I originally erroneously reported this as Census data; it's Social Security Administration data.
