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 housing development on TTSD enrollment, and forecasts of districtwide and individual school enrollments for the 2010-11 to 2019-20 school years. The Tigard-Tualatin School District (TTSD) enrolled 12,467 students in Fall 2009, a decrease of 128 students (1.0 percent) from Fall 2008. The loss occurred at both the elementary and high school levels, with decreases of 88 students (1.5 percent) in grades K-5 and 71 students (1.8 percent) in grades 9-12. District-wide enrollment in middle school grades 6-8 increased by 31 students (1.1 percent).
