Legislative districts of the Philippines

The Senate elected members through Senatorial Districts, a grouping of provinces and areas of the country, while the Assembly retained its way of representation.

With the passage of the 1940 Amendments to the 1935 Constitution, a bicameral Congress was established with a House of Representatives and a Senate.

The House of Representatives way of representation was like that of the Philippine Assembly, while the Senate's members were elected at large.

With the coming of the Interim Batasang Pambansa and the regular Batasan during the Marcos regime, representation was done in many ways: most members were elected by regions, some by appointment from the different sectors of the society such as youth and labor, and some were members of the Cabinet appointed by the President.

The present way of electing delegates to the House of Representatives is through legislative districts apportioned among the provinces, cities and the Metropolitan Manila Area and through a party-list system of registered national, regional and sectoral parties or organizations.
