In the least populated community, what is the most common location of all the reported crime incidents?
least populated refers to Min(Population); community refers to community_area_no; most common location refers to Max(Count(location_description))
SELECT T2.location_description FROM Community_Area AS T1 INNER JOIN Crime AS T2 ON T1.community_area_no = T2.community_area_no WHERE T1.population = ( SELECT MIN(population) FROM Community_Area ) AND T2.location_description IS NOT NULL GROUP BY T2.location_description
