Districts of Iloilo City
Iloilo City is a conglomeration of former cities and towns, which are now the geographical or administrative districts (boroughs) composed of seven: Arevalo, City Proper, Jaro, La Paz, Lapuz, Mandurriao, and Molo. All administrative districts are divisions of the lone congressional district of Iloilo City, and each is composed of barangays (barrios), with a total of 180 city barangays. The City of Iloilo was originally referred to only as what is now known as Iloilo City Proper until July 16, 1937, when the surrounding municipalities of Arevalo, La Paz, Mandurriao, and Molo were consolidated with the city after it was re-chartered by the American government. The city of Jaro followed suit and was absorbed into Iloilo City on January 7, 1941. The sub-district of Lapuz became a separate district from La Paz on December 17, 2008, making it the seventh and youngest district of Iloilo City. Description and list of barangays
