Ain is composed of four geographically different areas (Bresse, Dombes, Bugey and Pays de Gex), each of which contribute to the diverse and dynamic economic development of the department. In Bresse, agriculture and agro-industry are dominated by the cultivation of cereals, cattle breeding, milk and cheese production as well as poultry farming. In Dombes, pisciculture assumes greater importance, as does winemaking in Bugey.
Ain's prefecture is Bourg-en-Bresse. It is bordered by Jura to the north; Saône-et-Loire to the northwest; Rhône and the Lyon Metropolis to the southwest; Isère to the south; Savoie, Haute-Savoie and Switzerland to the east.
In the alphabetical ordering of French departments, used for postal and demographic purposes amongst others, Ain comes first and is thus assigned the number 01 as its department number. Provided by Wikipedia
