This thematic unit covers the historical evolution, the present
situation and the tendencies of socioterritorial conformation of the Metropolitan
Area of Buenos Aires.
The aim is to provide the user with the information gathered
by the AABA (Buenos Aires Environmental Atlas for its acronym in Spanish)
for an interpretation of the main periods of settlement of population, housing
developments, buildings and infrastructures, combined processes of expansion
and densification, functional specialization and appearance of axes and centers
that organize the urban space.

society requires a constant growth and the transformation of the physical
supply according to the new demands of the population .
This section of the atlas studies the physical evolution of the city
and its relationship with its inhabitants, its formal and informal organizations,
businesses and technological changes, focusing mainly in the evolution
of the land tenure and the configuration of residential housing, its
types and levels of material and social coverage.
