U.S. License Changes on After/Before 23 February 2007
from www.hamdata.com:

Hamdata information of four-month period 24 Feb 07 to 24 Jun 07

New Licensees 11,022 \......Positive growth of 671
Expirations 10,351 /
Class Changes 18,603
Call Changes 3,679

By comparison, the SIX-month periods ending 25 Jan 07 and 24 Jun 07
[inside square brackets] show a more averaged effect of FCC 06-178:

New Licensees 10,095 [ 15,002 ]
Expirations 12,815 [ 15,041 ]
Class Changes 5,921 [ 20,814 ]
Call Changes 2,815 [ 4,621 ]

The major change was in the ability of "lower" classes to upgrade,
indicated by the Class Changes. There is a slight upturn in Callsign
changes of June v. January which is probably prompted by the ability
to change Class. While new licensees are up by about 50%, the
expirations also rose in June v. January. For the two six-month
periods there is still a difference of new licensees not quite
offsetting the expirations.

Note that the period ending 25 January 2007 includes the FCC 06-178
announcement on 15 December 2006. That may or may not have
some slight bias on numbers. But the six-month period ending
24 June 2007 includes one month where code testing was required
for General and Extra classes, also a slight bias on numbers.

In the comparison of 24 June 2007 to 24 June 2006 the total
individual licensees (exclusive of Club calls) is down, 711,828 in
2007 compared to 728,431 in 2006 for a deficit of 6,603 for one
year. The slow shrinkage of total numbers continues as it has for
four years.
