Table schema:
CREATE TABLE table_name_19 (population INTEGER, altitude__mslm_ VARCHAR, area__km_2__ VARCHAR)

Question: Which Population is the highest one that has an Altitude (mslm) smaller than 229, and an Area (km 2) larger than 32.7?
SQL: SELECT MAX(population) FROM table_name_19 WHERE altitude__mslm_ < 229 AND area__km_2__ > 32.7
