Suppliers of postsecondary trained manpower data in Louisiana were surveyed during a project to obtain labor market information and occupational supply/demand information. All supply data were computerized and assigned to the appropriate training file. The data compiled fell into four major categories with regard to the method(s) of capture and introduction into the system. Various methods were used to develop these components of the Occupational Information System: occupational demand, occupational supply, crosswalk, and coding systems. Data indicated shortages in such occupations as general merchandise, law enforcement, heavy equipment operations and maintenance, secretarial occupations, and general clerical occupations. The largest surpluses were shown in real estate, practical nursing, barbering, welding, electrical and electronics technology, and air conditioning. [Appendixes, amounting to the largest portion of the report, include (1) correspondence and sample questionnaire; (2) tabular data presented by Labor Market Area in ascending order by the United States Office of Education code, in descending order by difference between demand and supply, in a summary table of unmet demand, and in descending order by difference between demand and supply for occupational training by educational/training entities; and (3) occupational and educational code crosswalk.] (YLB)
