I believe this is in reference to the past 4 years like the rest of the article.Although Liberty has not seen a great deal of new housing construction, Canuteson said 80 percent of new housing permits in the Kansas City metropolitan area were issued within the Liberty Public Schools boundaries.
Notice it doesn't say in Kansas City but in the entire area. If that's true, that makes sense why Shoal Creek is getting bus service with a reverse morning/evening commute. For Liberty to have service TO it for commuters is a big change.

hypoberle perhaps, but you don't get a $1.1 billion investment by Ford in an area with poor fortunes.“This is the most booming area in Kansas City,” Canuteson said.
Also, don't forget two high school opened for that general area in the past 4 years.
Staley was 2008
Liberty North was 2010.
elsewhere
Olathe NE was 2003
Lee's Summit West was 2004
Blue Valley SW was 2010
So you can see the growth areas of the city includes KC/Liberty as much as it does JoCo. A huge number of Liberty residents are KC workers too.
