Question: What is the highest Crude Death Rate (Per 1000), when Natural Change (Per 1000) is less than 5.2, when Average Population (x 1000) is 305, when Crude Birth Rate (Per 1000) is 16.1, and when Natural Change is greater than 954?
SQL: SELECT MAX("crude_death_rate_per_1000") FROM tuv_population WHERE "natural_change_per_1000" < 5.2 AND "average_population_x_1000" = 305 AND "crude_birth_rate_per_1000" = 16.1 AND "natural_change" > 954

Question: What is the lowest Natural Change, when Natural Change (Per 1000) is 19.1, and when Crude Birth Rate (Per 1000) is less than 28.3?
SQL: SELECT MIN("natural_change") FROM tuv_population WHERE "natural_change_per_1000" = 19.1 AND "crude_birth_rate_per_1000" < 28.3
