The recent suburban growth of the Dallas-Fort Worth Metroplex has caused LISD to grow at a great pace, becoming the 94th-largest school district in the United States in 2006. Proximity calculated a 28.56% increase in student population from 2000 to 2006; LISD was declared the 17th largest school district in the State of Texas in 2008. To help maintain this growth, in May 2008, voters approved a $697 million bond package.
