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 2011-12 to 2020-21 school years. The Tigard-Tualatin School District (TTSD) enrolled 12,393 students in Fall 2010, a decrease of 74 students (0.6 percent) from Fall 2009. The loss occurred at both the elementary and middle school levels, with decreases of 41 students (0.7 percent) in grades K-5 and 123 students (4.2 percent) in grades 6-8. Conversely, district-wide enrollment in high school grades 9-12 increased by 90 students (2.3 percent).
