The Tigard-Tualatin School District (TTSD) enrolled 12,460 students in Fall 2007, an increase of 153 students (1.2 percent) from Fall 2006. Growth was concentrated in the secondary grades, with increases of 59 students (2.1 percent) in middle school grades 6-8, and 93 students (2.4 percent) in high school grades 9-12. Elementary grades K-5 enrolled only one more student in Fall 2007 compared with Fall 2006. This report presents the results of a demographic study conducted by the Portland State University Population Research Center (PRC). The study includes analysis of population, housing and enrollment trends affecting the District in recent years, estimates of the impacts of new housing development on TTSD enrollment, and forecasts of district-wide and individual school enrollments for the 2008-09 to 2012-13 school years. The forecasts indicate that overall TTSD enrollment will continue to increase during the next five years, due largely to net in-migration of families with children. Single family housing development in 2007 has been slower than in recent years, as homebuilders have adjusted to the slower housing market that has affected the Portland metropolitan region. But construction and sales are continuing in several subdivisions in the District, at least two large multi-family developments are planned, and redevelopment and infill is also adding to the District’s housing stock.
