Computer programmers held about 455,000 jobs in 2004. Programmers are employed in almost every industry, but the largest concentration is in computer systems design and related services. Large numbers of programmers also work for telecommunications companies, software publishers, financial institutions, insurance carriers, educational institutions, and government agencies.Many computer programmers are employed on a temporary or contract basis or work as independent consultants, providing companies expertise with new programming languages or specialized areas of application. Rather than hiring programmers as permanent employees and then laying them off after a job is completed, employers can contract with temporary help agencies, with consulting firms, or with programmers themselves. A marketing firm, for example, may require programming services only to write and debug the software necessary to get a new customer database running. Bringing in an independent contractor or consultant with experience in a new or advanced programming language enables the firm to complete the job without having to retrain existing workers. Such jobs may last anywhere from several weeks to a year or longer. There were 25,000 self-employed computer programmers in 2004.
