Defining Mega Manila
Conceptualizing a Megalopolis
Mega Manila represents a vast megalopolis situated on the island of Luzon in the Philippines. It is generally understood to encompass the administrative regions of Central Luzon, Calabarzon, and Metro Manila. On occasion, significant portions of Mimaropa are also included in its definition. This term is frequently employed in media and public discourse to denote the provinces functionally linked to Manila, distinguishing it from the more academically precise term "Greater Manila Area," which specifically addresses the urban expansion beyond Metro Manila's boundaries.
Philippine Information Agency (PIA) Definition
The Philippine Information Agency (PIA) defines Mega Manila broadly, including the National Capital Region (Metro Manila) alongside the suburban areas of Central Luzon, Calabarzon, and Mimaropa. This definition, used for informational outreach, encompasses a substantial portion of Luzon's landmass and population, reflecting a wide-reaching sphere of influence.
National Economic and Development Authority (NEDA) Perspective
The National Economic and Development Authority (NEDA), in collaboration with the Japan International Cooperation Agency (JICA), defines Mega Manila more specifically for planning purposes. This definition typically includes Metro Manila and the surrounding provinces of Bulacan, Rizal, Cavite, and Laguna. NEDA also utilizes the term "Greater Capital Region (GCR)" to refer to Metro Manila, Central Luzon, and Calabarzon, highlighting a strategic planning area.
TV Rating Companies' Scope
For television audience measurement, agencies like AGB Nielsen Philippines and Kantar Media Philippines employ a stricter definition of "Mega Manila." This typically comprises Metro Manila and the provinces of Bulacan, Cavite, Laguna, and Rizal. This definition, while narrower than the PIA's, closely approximates the contiguous built-up urban area surrounding Manila.
Economic Significance

Mega Manila is the economic powerhouse of the Philippines. In 2024, its Gross Domestic Product (GDP) was estimated at approximately US$260 billion, constituting a significant 56% of the nation's total GDP. This concentration of economic activity underscores its critical role in the country's development.
The economic output is distributed across its constituent regions, with Metro Manila contributing the largest share, followed by Calabarzon and Central Luzon.

Greater Manila Area: Urban Sprawl
The Greater Manila Area represents the continuous urbanized region extending beyond Metro Manila's administrative boundaries. It includes Metro Manila itself and contiguous urban settlements within surrounding provinces, primarily in Central Luzon and Calabarzon. This definition captures the physical extent of urbanization and its interconnectedness.
Greater Capital Region (GCR): Planning Framework
