Not sure if these are the trends you are looking for, but here something:
* Nationally, new home construction makes up less than 12% of all home sales.
* In Kootenai County, it was at 32% for quite a while.
* Recently, Kootenai County's new construction sales are down to 27% of all home sales and *appear* to be decreasing.
This is actually very good news for home owners because right now, competition is new construction, REO's and short sales. With new home sales decreasing, it allows resales to increase. New construction has been keeping resales prices suppressed, in other words - if you want to sell a home you've lived in, you'd have to price it BELOW new construction comparables right now, even though your home is likely to have more upgrades, full landscaping, etc.
However, it's not necessarily good news for everyone... in an economy that is somewhat heavily dependent upon construction jobs, this means more people will either be out of work or looking for work in other locales - either working out of town or moving out of town.
Overall, I firmly believe that a strong decrease in new construction sales will ultimately be much better for our housing economy.
