REAPPORTIONING THE LONE LEGISLATIVE DISTRICT AND

EXPLANATORY NOTE
Data from the Philippine Statistics Authority (PSA) indicate the following 
trend in the population of Iloilo City as follows: 209,700 (1970 census); 244,800 
(1980 census); 309,500 (1990 census); 366,400 (2000 census); 424,600 (2010 
census);1 and 447,992 (2015 census).2 * According to the PSA, the population of 
Iloilo City would double in 47 years if its average annual Population Growth Rate 
(PGR) of 1.49% during the period of 2000 to 2010 continues. Since 1987 when 
Iloilo City was provided its own congressional district, the City has remained a 
lone legislative district until now.
Pertinent provisions of Article VI of the 1987 Constitution state:
Sec. 5 (3). “Each legislative district shall comprise, as far as practicable, 
contiguous, compact, and adjacent territory. Each city with a population of at least 
two hundred fifty thousand, or each province, shall have at least one 
representative.”
Sec. 5 (4). “Within three years following the return of every census, the 
Congress shall make a reapportionment of legislative districts based on the 
standards provided in this section.”
While referring to the case of Mariano v. COMELECi, the Supreme Court 
held in the case of Aquino v. COMELEC4 that “while Sec. 5 (3), Article VI of the 
Constitution requires a city to have a minimum population of 250,000 to be 
entitled to a representative, it does not have to increase its population by 
another 250,000 to be entitled to and additional district.”
Consistent with the above-mentioned cases and in consonance with the 
Constitutional principle of proper democratic representation, this legislative
