CREATE TABLE table_19210 ("Name" TEXT, "2011 Census" FLOAT, "2006 Census" FLOAT, "% change" TEXT, "Land area  ( km\\u00b2 ) " TEXT, "Density  ( pop/km\\u00b2 ) " TEXT, "Population rank" FLOAT)

When the change is 8.8%, what is the density (pop/km )?
SELECT "Density (pop/km\u00b2)" FROM table_19210 WHERE "% change" = '8.8'
SELECT "Density (pop/km\u00b2)" FROM "table_19210" WHERE "% change" = '8.8'
