Final answer:
Smaller, more specific groups of occupations within a Cluster are known as occupational groups, which categorize similar professions under broader industry categories. Clustering helps in understanding career paths and can also refer to co-location.
Step-by-step explanation:
Within each Cluster, there are smaller, more specific groups of occupations known as occupational groups. For instance, in the Cluster of healthcare, one might find Healthcare support occupations and Healthcare practitioners and technical occupations as some of the occupational groups. These groups help organize similar professions under broader industry categories, aiding individuals in understanding and exploring career paths.
Clustering is a way of grouping things with similar characteristics, and it can also refer to the concept of co-location, where different items or groups are found in proximity to each other leading to agglomeration, which is a shared feature among clusters in various contexts, such as businesses, populations, and communities.
