Abstract: Systems, methods, and devices for modeling labor markets and providing workforce estimates based on labor market data. Labor market data may be received from disparate data sources and the labor market data may be mapped to an occupation taxonomy and a confidence interval may be determined for the mapping. A workforce size for an occupational classification within a geographic region may be determined based on the mapping and the confidence interval. The workforce estimate may be transmitted based on the occupational classification and the geographic region.

Abstract: A scaffold having a platform, support legs, support beams supporting the platform, side rails connecting the legs, guard rails, and spring-biased slidable pins securing the support legs to the support beams. Each slidable pin is at an acute angle to the plane of the support platform and axis of its associated support leg and support beam (preferably at 56. degrees to the axis of the associated support leg). This acute-angle pin structure renders that scaffold more rigid and secure while preserving the ability to easily assemble, adjust, and dis-assemble the scaffold. The platform also includes spacers inserted between the platform and support legs to force the legs away from the platform, eliminate play in the structure, and make the scaffold more rigid and secure.
