What is the ratio in percentage of Santa Clara County schools that are locally funded compared to all other types of charter school funding?
Ratio in percentage = (count(locally funded schools in Santa Clara) / count(all funding type schools in Santa Clara) * 100%
SELECT CAST(SUM(CASE WHEN FundingType = 'Locally funded' THEN 1 ELSE 0 END) AS REAL) * 100 / SUM(CASE WHEN FundingType != 'Locally funded' THEN 1 ELSE 0 END) FROM schools WHERE County = 'Santa Clara' AND Charter = 1
