Aggregation vs. Agglomeration: What's the Difference?

Edited by Harlon Moss || By Janet White || Published on December 9, 2023
Aggregation refer to collection of items often from varied sources; Agglomeration refers to clustering of similar items, often in a mass.

Key Differences

Aggregation refers to the act of gathering or accumulating items from various sources into a collective group. It often involves assembling diverse elements into an organized whole. Agglomeration, in contrast, is the process of clustering or grouping similar items together, forming a mass or cluster. It typically involves the amassing of closely related items or particles.
Aggregation can be seen in data collection, where information from different sources is compiled into a comprehensive dataset. Agglomeration is more like clustering in geography or economics, where similar entities, such as businesses or industries, group together in a concentrated area.
In social contexts, aggregation might involve compiling opinions or feedback from a diverse range of people. Agglomeration, on the other hand, would refer to the gathering of like-minded individuals or groups, often leading to a homogenous community or network.
In scientific terms, aggregation can describe the combination of various substances or elements to form a compound. Agglomeration, however, is often used in the physical sciences to describe the process of particles or materials clumping together, like in metallurgy or sedimentology.
Aggregation is a broader term and can be applied to a variety of contexts, from data to social phenomena. Agglomeration is more specific and often used in physical sciences, urban planning, and economics, referring to the clustering of similar entities.
