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_46090 ( "Country" text, "Population (July 2005 est.)" real, "Land Area (km\u00b2)" real, "% of arable land (2005 est.)" text, "Arable Land (km\u00b2)" real, "Population Density (pop per km\u00b2)" real )

### Question ###
What is the total population of American Samoa (US) that has less than 16,280 km arable land, less than 240 km land area, and has a population density of more than 291?

### Accurate SQL ###

SELECT COUNT("Population (July 2005 est.)") FROM table_46090 WHERE "Arable Land (km\u00b2)" < '16,280' AND "Land Area (km\u00b2)" < '240' AND "Country" = 'american samoa (us)' AND "Population Density (pop per km\u00b2)" > '291'
