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_42586 ( "Average population (x 1,000)" text, "Live births" text, "Deaths" text, "Natural change" text, "Migration" text, "Crude birth rate (per 1,000)" real, "Crude death rate (per 1,000)" real, "Natural change (per 1,000)" real, "Migration (per 1,000)" real )

### Question ###
How many Crude death rate (per 1,000) has a Migration (per 1,000) larger than -5.06, and a Natural change (per 1,000) larger than 7.06? Question 1

### Accurate SQL ###

SELECT AVG("Crude death rate (per 1,000)") FROM table_42586 WHERE "Migration (per 1,000)" > '-5.06' AND "Natural change (per 1,000)" > '7.06'
