Table schema:
CREATE TABLE table_name_57 (number_of_households INTEGER, per_capita_income VARCHAR, population VARCHAR)

Question: What is the highest Number of Households, when Per Capita Income is "$25,557", and when Population is less than "22,330"?
SQL: SELECT MAX(number_of_households) FROM table_name_57 WHERE per_capita_income = "$25,557" AND population < 22 OFFSET 330
