Table schema:
CREATE TABLE table_name_21 (pop__2010_ INTEGER, latitude VARCHAR, land___sqmi__ VARCHAR, ansi_code VARCHAR, longitude VARCHAR)

Question: Which Pop (2010) has an ANSI code smaller than 1036864, and a Longitude larger than -98.46611, and a Land (sqmi) smaller than 36.238, and a Latitude smaller than 48.144102?
SQL: SELECT AVG(pop__2010_) FROM table_name_21 WHERE ansi_code < 1036864 AND longitude > -98.46611 AND land___sqmi__ < 36.238 AND latitude < 48.144102
