Course: 22: 390: 501 Essentials of Strategic Written Communications

A sector is a subset, or group, which shares similar components. For our purposes then, a market sector is a subset or grouping of companies which share similar components, such as technologies or products.

Keep in mind that sectors can be part of a broader industry, or operate within multiple industries. Since most library resources are created at the industry level, you will have to extract information relevant to your sector. If the word "industry" or "sector" is being used by itself, then it's generally safe to take either word to mean the same thing.a sector is considered to be the broader of the two. Sectors slice the economy into big chunks -- each of which is home to multiple industries. Here's the kicker:The two terms are sometimes reversed.

Example: Construction is an industry.  Heavy equipment and construction machinery could be a market sector. 

If you are searching library databases such as Business Source Premier or IBISWorld, you can search by  North America Industry Classification System  (NAICS) or Standard Industry Classification (SIC code). Some resources are organized according to industry classification systems, such as the Standard Industry Classification (SIC) or North America Industry Classification System (NAICS). >>>>>>>>>>>>>It may be helpful to write these codes down as you find them when starting your research, as they may be useful if you hit a roadblock along the way.

If you search for a NAICS code, use the 2007 number as most resources have not yet moved to the 2012 codes.

Overviews may contain revenue analyses, market share and segmentation, and forecasts.
