From 2005 to 2015, the number of annual new registrations increased 13% to over 79,700. But there were fluctuations over the 10-year period. In particular, there were two instances when new registrations declined. First, there was a decline in the number from 2008 to 2009, followed by a second decline from 2014 to 2015. In each case, a drop of about 14,000 new registrations was observed compared with the previous year. These two declines coincided with periods of economic decline.
