Marikina Population and Voter Stats

I recently visited the National Statistical Coordination Board website,  searched for Marikina and got some interesting stats.

As of August  2007, the Marikina City population is a bit over 420,000 with nearly 200,000 registered voters (figures on registered voters are partial data from Commission on Elections (COMELEC).).   I didn't realize that I lived in a city with almost half a million residents.
