[2] According to the 2002 census of the National Statistics Institute, Casablanca spans an area of 952.5 km2 (368 sq mi) and has 21,874 inhabitants (11,127 men and 10,747 women).

[2] As a commune, Casablanca is a third-level administrative division of Chile, administered by a municipal council, which is headed by a directly elected alcalde.

The Casablanca Valley is a wine-producing region 75 km (47 mi) northwest of Santiago.

Vines were first planted here in the mid-1980s during the revitalization of the Chilean wine industry and it quickly became known for its white wines, most notably Sauvignon Blanc and Chardonnay, as well as Pinot Noir, which thrives in its cooler climate.

Although the valley is located at 33°S, much closer to the Equator than any European vineyard, viticulture here is possible because of the cooling influence of the Pacific Ocean, in the shape of cool morning fog and greater cloud cover than is found elsewhere in the north of Chile.
