Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent handle metropolitan areas by definition, delineation method, population data and governance, noting that figures depend on the definition used.

A densely populated urban core together with surrounding territories linked by commuting, economy and infrastructure, defined differently by national statistical offices, such as metropolitan statistical areas, metropolitan regions and metropolitan cities.

What it is for: Planning, statistics, transport and economic analysis.

It can be find population figures by definition; compare metropolitan areas consistently; identify governing or planning bodies; understand delineation methods.

Distinguishing features

Functional urban region

Definitions vary by country

Based on commuting and density

May lack a single government

What it looks like

Cities and suburbs connected by transport networks, shown on maps as delineated regions.

How it is recognised

Core city plus commuter belt

Official delineations

City proper boundaries are narrower
