"An “industry” describes the collection of companies and organizations connected with producing a particular product or service, such as cars, software, health care, or energy.
Industry research can help shed light on which industries are growing and which are declining in a local area. Knowing where industry growth is high can guide you to focus your job search in a certain location, target specific companies for job applications, or strengthen your knowledge of a growing industry. Keep in mind that some occupations appear in many different industries."
