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 district‐wide and individual school enrollments for the 2012‐13 to 2021‐22 school years. The Tigard‐Tualatin School District (TTSD) enrolled 12,366 students in Fall 2011, a decrease of 27 students (0.2 percent) from Fall 2010. This is the third consecutive year of K‐12 enrollment loss, but the change was small compared with the loss of 128 students in 2009‐10 and 74 students in 2010‐11. District elementary schools experienced a net loss of 73 students (1.3 percent) in 2011‐12, and 202 students (3.5 percent) for the three year period since 2008‐09. Middle grades (6th‐8th) gained 51 students (1.8 percent) in 2011‐12, mostly due to a larger sixth grade replacing a smaller eighth grade. District‐wide enrollment in high school grades 9‐12 was essentially stable, decreasing by just five students (0.1 percent).
