In the United States:
The Unclassified occupation (99-9999) is a special SOC code Lightcast uses for the Extended Proprietors class of worker (Class 4). The Unclassified occupation is used as an occupational bucket for industries that don’t have self-employed staffing patterns.
Underemployment
Underemployment data helps communities identify the portions of their population who are underutilizing their skills or time. There are three types of underemployment:
Over-skilled
Under-payed
Low hour
The underemployment data in the Economy Overview compares the educational attainment of the working age population (25+) to the number of jobs (25+) by typical entry level education in the region.
Example
15% of region A’s population has a high school diploma. 34% of jobs only require a typical entry level education of a high school diploma. This means that 19% of the region’s working age population would be over-skilled and have a higher degree than necessary for this jobs.

In Canada:
The Unclassified occupation (X000) is used as an occupational bucket for the Unclassified industry, which does not have a known staffing pattern. Without a staffing pattern, it’s not possible to translate industry employment to occupation employment. Therefore Lightcast uses an Unclassified NOC code to hold occupational information where an industry classification was not provided.
