Table schema:
CREATE TABLE table_name_24 (population INTEGER, area__km_2__ VARCHAR, density__pop_per_km_2__ VARCHAR, rank VARCHAR)

Question: What is the average population of the region with a density less than 487, a rank of 9, and an area larger than 377,944?
SQL: SELECT AVG(population) FROM table_name_24 WHERE density__pop_per_km_2__ < 487 AND rank = 9 AND area__km_2__ > 377 OFFSET 944
