CREATE TABLE table_14252 ("Rank" TEXT, "Province" TEXT, "Population  ( 2011 ) " FLOAT, "Area  ( km\\u00b2 ) " FLOAT, "Density  ( per km\\u00b2 ) " FLOAT)

what is the Density (per km ) when the Area (km ) is 372,889 and the population (2011) is 1,145,861?
SELECT SUM("Density (per km\u00b2)") FROM table_14252 WHERE "Area (km\u00b2)" = '372,889' AND "Population (2011)" > '1,145,861'
SELECT SUM("Density (per km\u00b2)") FROM "table_14252" WHERE "Area (km\u00b2)" = '372,889' AND "Population (2011)" > '1,145,861'
