Every year the U.S. Department of Labor conducts a national survey of over 400,000
                            employers in every state and in all industry divisions. This survey is conducted
                            through the Occupational Employment Statistics (OES) program. Every other year the
                            department publishes outlook information based on these surveys.
                        
                            Each outlook period covers 10 years. For example, in 2003 the outlook information
                            was published for 2004-2014. Employers are asked to report the number of employees
                            in about 770 different occupations that cover the entire U.S. labor market.
                        
                            From this information, staffing patterns for different industries are established.
                            Industry growth is projected into the future based on past trends and current economic
                            conditions. Industry staffing patterns are then applied to the industry projections
                            to obtain occupational projections.
                        
                            In many cases, these occupations are broad enough to cover many more detailed specialties
                            of an occupation. A specific occupation may be included in a broader occupational
                            category for which labor market data is available. When you look at the statistics
                            for a broad category, be aware that the employment data for a specific field may
                            differ.
