The Tigard-Tualatin School District (TTSD) enrolled 12,300 students in Fall 2006, an increase of 167 students (1.4 percent) from Fall 2005. Growth was concentrated in the elementary grades (K-5), which grew by 195 students (3.6 percent) between Fall 2005 and 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 2007-08 to 2011-12 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. Recent subdivision approvals will allow single family home construction to continue at its current pace for the next two to three years, but no new multiple family rental developments have been approved in the past two years. In some parts of the District, a dwindling supply of available residential land has already caused housing growth to slow, but growth in other areas has the potential to generate enrollment growth throughout the next five years. Also, the growing Hispanic population in the District compensates for the graduation of the "echo boom" enrollment bulge currently enrolled in high school grades.
