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 ###

### Question ###

### Accurate SQL ###

SELECT "Administrative division" FROM table_26498 WHERE "Population density (/km\u00b2 2011)" = '1,604.3'
