Shift-share analysis produces results that can be valuable for diagnosing, describing and building understanding of major differences between the industry pattern of employment growth locally and nationwide trends. Choose from Wisconsin's 72 counties, select any time interval between 1969-2000 under the Standard Industrial Classification (SIC) or from 2001-2022 under the North American Industrial Classification System (NAICS), and generate shift-share analysis results for local employment growth compared with the nation at large. This module outputs graphical representations of employment growth for the given time interval, a tabular summary of shift-share results, a tailored disucssion on how to interprete the results, and a thorough technical summary of how the results are derived.
