Population Research Center, Rynerson, Charles, Siu, Vivian Year: 2007 The Oregon City School District (OCSD) enrolled 7,764 students in Fall 2006, a decrease of 189 students (2.4 percent) from Fall 2005. Much of the K-12 decrease was due to a relatively small kindergarten class entering and a large 12th grade class graduating. Also, the figures do not include enrollment at the District’s two charter schools, both of which opened in Fall 2006 and enrolled some students who were previously enrolled in districtrun schools. 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 and forecasts of district-wide and individual school enrollments for the 2007-08 to 2011-12 school years.

  Citation × Citation Citation Abstract Copy Title: Hillsboro School District: Population and Enrollment Forecasts, 2006-07 to 2015-16 Author: Portland State University. Population Research Center, Rynerson, Charles, Siu, Vivian Year: 2006 The Hillsboro School District (HSD) has experienced enrollment growth throughout the 1990s and 2000s. This report presents the results of a forecast conducted by the Portland State University Population Research Center (PRC) indicating that HSD enrollment will continue to grow during the next ten years. PRC’s methodology links enrollment trends with population dynamics and housing development. Population and housing are closely related to employment levels. By itself, the District’s past growth is no guarantee of future long-term growth, but in the context of expected employment, population, and housing growth, enrollment is likely to continue to increase at all grade levels. Washington County currently has the lowest unemployment rate in the state, and employment in the region is forecast to grow by over 16 percent in a ten year period. The county’s population is forecast to grow by 22 percent. Most significantly for the area within the HSD boundaries, there are about 3,500 housing units in new single family subdivisions and multi-family housing developments currently under construction, recently approved, or awaiting approval.4 This development has the potential to increase the District’s housing stock by eight percent within the next three years.

Population Research Center, Rynerson, Charles, Siu, Vivian Year: 2006 The area served by the Three Rivers School District (TRSD) has experienced population and housing growth in recent years, but the District’s K-12 school enrollment in 2006-07 is 17 percent lower than its 1995-96 peak. Total K-12 enrollment has fallen in each of the past 11 years and is now lower than in any of the past 30 years. Losses have been greatest in the elementary grades (K-5), which enroll 27 percent fewer students than in 1996-97. The middle grades (6-8) have lost 20 percent in enrollment during the same period, while the high school grades (9-12) have lost only three percent. This report presents the results of a forecast conducted by the Portland State University Population Research Center (PRC) indicating that overall TRSD enrollment will continue to decrease during the next five years, until 2011-12, mostly due to the current smaller elementary and middle school classes moving up to the high school level. Although elementary enrollment is expected to “bottom out” within the next two to four years and begin to grow slightly, the offsetting effect of smaller high school enrollment means that overall K-12 enrollment will be stable at best during the 2011-12 to 2016-17 period. PRC’s methodology links enrollment trends with the area’s population dynamics. As employment, population, and housing growth in the region continues, the enrollment declines should slow, and overall enrollment will stabilize within the 5,000 to 5,100 student range over a period of several years, according to this forecast.

Population Research Center, Rynerson, Charles, Siu, Vivian Year: 2006 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.

This was the third consecutive year of K‐12 growth, a reversal from the 12 consecutive years of enrollment losses between 1997 and 2008.

This report includes analysis of population, housing and enrollment trends affecting the District in recent years, forecasts of district‐wide enrollment, and Enrollment Forecasts by area of residence (high school clusters, school attendance areas) and by individual school of attendance for the 2012‐13 to 2025‐26 school years. For the district‐wide forecast, three scenarios of population and enrollment changes were developed: a most‐likely, or medium, growth scenario; a scenario for lower growth; and a higher growth scenario. All three of the growth scenarios for the PPS district‐wide Enrollment Forecasts use similar mortality, fertility, and capture rates during the 14 year horizon. The differences between the three scenarios are primarily due to different assumptions about the levels of net migration (the net movement into and out of the District) among families with children.

Middle grades (6th‐8th) in District schools gained enrollment in 2012‐13, and are just 59 students (2.0 percent) below their 2009‐10 peak. District‐wide enrollment in high school grades 9‐12 has been virtually unchanged since 2010‐11 and remains near its peak. In contrast to the K‐5th grade enrollment decline, Fall 2012 kindergarten enrollment of 939 in TTSD schools was the largest ever, 62 students larger than in Fall 2011. However, the kindergarten growth is not likely to be sustained, as births to District residents peaked in 2006‐07, the birth cohort that entered kindergarten in Fall 2012.
