answer: SELECT SUM(pop_density_people_km_2) FROM table_name_47 WHERE population__percentage_of_eu = "0.1%" AND area__percentage_of_eu = "0.1%" AND population_in_millions > 0.5
context: CREATE TABLE table_name_47 (pop_density_people_km_2 INTEGER, population_in_millions VARCHAR, population__percentage_of_eu VARCHAR, area__percentage_of_eu VARCHAR)
