AN ACT REAPPORTIONING THE PROVINCE OF BULACAN INTO 
SIX (6) LEGISLATIVE DISTRICTS
EXPLANATORY NOTE
The province of Bulacan comprises of 21 municipalities, three cities and 569 
barangays1 with a population of 3,292.071 as of 2015. The province was initially 
divided into five legislative districts as follows:
District I - Bulacan, Calumpit, Hagonoy, City of Malolos, Paombong, Pulilan 
District II - Balagtas, Baliwag, Bocaue, Bustos, Guiguinto, Pandi, Plaridel 
District III - Angat, Dona Remedios Trinidad, Norzagaray, San Rafael, San 
lldefonso, San Miguel
District IV - Marilao, Meycauayan, Obando, Sta. Maria
But in the recent years, the municipalities of San Jose del Monte, Malolos, and 
Meycauayan were converted into cities. Moreover, San Jose del Monte was 
separated from District IV, and became a separate district in 2003 by virtue of Republic 
Act No. 9230. In 2009, Malolos City was set to become another separate district by 
virtue of Republic Act No. 9591, until the same was struck down by the Supreme Court 
due to failure to meet the required minimum population of 250,000.
This bill proposes the reapportionment of the legislative districts of Bulacan 
from five to six. Each legislative district shall comprise, as far as practicable, 
contiguous, compact, and adjacent territory.

Given the increase in the population of Bulacan since 1987 until today, and the 
varied concerns of the cities and/or municipalities comprising it, the immediate 
passage of this bill is earnestly sought.
