The topography comprises gently-rolling glacial till, with relatively fertile soil. As late as 1880 the island had a resident population of around 450, mainly engaged in fishing and small-scale farming, but today the population has reduced to approximately 20 people. Previously home to Whiddy Island Naval Air Station the island is noted for its oil terminal facilities - and the related Whiddy Island Disaster.
