This article was in Crosscuts in late September. It's interesting reading and it's worth noting,
"The Latino population of Seattle has seen steady growth: from 3.7 percent of the city's inhabitants in 1990 to 5.3 percent in 2000 and 6.3 percent in 2005."
"Even these numbers, however, may not display the full magnitude of the demographic change. School district enrollments in the Seattle area show consistently higher percentages of Hispanic students than in the population at large. As of October 2006, 11.3 percent of students enrolled in the Seattle School District were Latino."
"Statewide, Latino enrollments are growing faster than any other ethnic group in a large majority of school districts."
