@eyemgh, you are of course correct. It’s just that it seems to be spread unevenly amongst the schools in my area. More of a curiosity than a concern.
@VickiSoCal, that is a significant difference. Part of it might be the different demographics of the local areas. Vallejo/Fairfield to the southwest and Sacramento metropolitan area to the east are some of the most racial diverse cities in the country. The Sacramento and Solano County areas have Asian populations of about 14% where the SLO County Asian population is under 3%.
None of that factors in how many students apply to both schools from out of the area. Clearly, each is very popular outside of the local attendance areas.
