Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_78657 ( "Average population (x 1000)" text, "Live births" text, "Deaths" text, "Natural change" text, "Crude birth rate (per 1000)" real, "Crude death rate (per 1000)" real, "Natural change (per 1000)" text )

### Question ###
Which Natural change has a Crude death rate (per 1000) larger than 9, and Deaths of 40 399?

### Accurate SQL ###

SELECT "Natural change" FROM table_78657 WHERE "Crude death rate (per 1000)" > '9' AND "Deaths" = '40 399'
