Actually there are. Enrollment in California public schools is increasing by about 10% a year for the last 3 years.
Enrollment by Hispanics is inceasing at the greatest rate of any ethnic class. From a low of about 25% in 1981 to an average of about 43% per year for the last three years. Hispanics will soon constitute 50% of the enrollment in California public schools.
About 80% of the Hispanic children enrolled in public schools in 2000 could trace their residence to illegal immigration since 1950. That number will top 90% in the next five years if the immigration and birth rate trends hold.
So why are these northern California counties apparenlty against the trend. Two reasons: Gentrification and liberal, social pressure.
Gentrification is causing land values in these counties to be beyond the means of the typical illegal alien. The social pressure associated with these liberal elite enclaves is causing landlords in the area to not turn a blind eye to multiple families renting the house next door. The wealthy liberal will not tolerate 4 generations and 20 members of the extended Gonzales family to occupy the estate next door even if their combined income is sufficient to rent the old mansion.
Yes Virginia there is a Santa Clause. He's called gentrification.
