Question: Which Average population (x 1000) has a Crude death rate (per 1000) smaller than 10.9, and a Crude birth rate (per 1000) smaller than 19.7, and a Natural change (per 1000) of 8.7, and Live births of 54 263?
SQL: SELECT "average_population_x_1000" FROM "after_ww_ii" WHERE "crude_death_rate_per_1000"<10.9 AND "crude_birth_rate_per_1000"<19.7 AND "natural_change_per_1000"='8.7' AND "live_births"='54 263';
