family of the Malayo-Polynesian languages. Because Iloilo was a former Spanish colony for 300 years, Hiligaynon is heavily influenced by the Spanish language with a plethora of loaned words (Guerra, Puerta, Golpe, Aguanta, Puerto, Calle, and Edificio, among others). Hiligaynon is mainly concentrated in the provinces of Iloilo, Guimaras and Negros Occidental. The language is referred to as "Ilonggo" () in Iloilo and Negros Occidental. More precisely, "Ilonggo" is the ethno-linguistic group referring to the inhabitants of Iloilo and the culture associated with native Hiligaynon speakers. The distinction between the terms, Ilonggo and Hiligaynon, is unclear however, as many townspeople state that Hiligaynon is the language being spoken and Ilonggo is a term used to refer a person living in Iloilo or its associated culture and ethnicity. Population Based on the 2010 Census of Population and Housing (CPH), Iloilo City, a highly urbanized city in the province of Iloilo, posted a total population of 424,619 persons as of May 1, 2010. This is larger by 58,228 persons compared to its total population of 366,391 persons counted in the 2000 CPH. The increase in the population count from 2000 to 2010 translated to an average annual population growth rate (PGR) of 1.49 percent. This is lower than the 1.70 percent annual PGR of the city between the census years 1990 and 2000. If the average annual PGR recorded at 1.49 percent during the period 2000 to 2010 continues, the population of Iloilo City would double in 47 years. Forty years ago, the population of Iloilo City was only 209,738 persons. This population size is one-half of the population of the city in the 2010 CPH. Among the 180 barangays comprising Iloilo City, barangay Calumpang was the most populous. Its population size was 2.6 percent of the total population of the city. San Juan came in second in terms of population size, with 2.3 percent share. This was followed by Balabago and Tabuc Suba (Jaro) with 2.0 percent each, Calaparan and So-oc with 1.9 percent each, Molo Boulevard with 1.8 percent, Santo Niño Sur with 1.7 percent, Cubay and Obrero-Lapuz with 1.6 percent each, and Bolilao with 1.5 percent. The rest of the barangays contributed less than 1.5 percent each. The least populated barangay was Roxas Village with less than 0.1 percent share to the total population of the city. It was also the least populated barangay in 2000. Religion As the
