Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
What is the sum of Natural Change, when Natural Change (Per 1000) is greater than 5.4, when Crude Death Rate (Per 1000) is less than 14.3, when Live Births is less than 6,950, and when Crude Birth Rate (Per 1000) is less than 28.2?

### Inputs:
table_name: table, columns: ['Average population (x 1000)', 'Live births', 'Deaths', 'Natural change', 'Crude birth rate (per 1000)', 'Crude death rate (per 1000)', 'Natural change (per 1000)']

### Response:
SELECT SUM Natural change FROM table WHERE Natural change (per 1000) > 5.4 AND Crude death rate (per 1000) < 14.3 AND Live births < 6,950 AND Crude birth rate (per 1000) < 28.2
