"Labor Market Information (LMI) is an applied science; it is the systematic collection and analysis of data which describes and predicts the relationship between labor demand and supply." The States' Labor Market Information Review, ICESA, 1995, p. 7.
A growing or declining industry is defined as an industry group's employment level increasing or decreasing for two quarters by 5.0% or more over the year. For example, all industries that grew or declined in employment by at least 5.0% from 2018Q1 to 2019Q1 and subsequently from 2018Q2 to 2019Q2 were included in the respective lists.
Industries are defined through the North American Industry Classification System (NAICS). For this research, growing and declining industries are determined at the three-digit subsector level. For more information on NAICS, please see http://www.census.gov/epcd/www/naics.html.
The database used to generate this information was the Quarterly Census of Employment and Wages (QCEW) file, which has roughly a half-year time lag from the distribution of this report. Every quarter, when a QCEW date become available, growing and declining industry information is updated. Only subsectors with employment sizes of 100 or more are included in these lists. While employment in other industries may meet the growth criteria, this growth is taking place in industries with less employment.
For example, on the growing industry report, average monthly employment for electrical equipment and appliance manufacturing (NAICS 335) grew by 45.7% (105 jobs) over the year in 2019Q2 and by 47.8% (111 jobs) over the year in 2019Q1, thus qualifying as a growing industry for 2019Q2 with an average change of 46.7%. Conversely, on the declining industry report, air transportation (NAICS 481) decreased by 19.0% over the year in 2019Q2 and by 9.4% over the year in 2019Q1, qualifying as a declining industry for 2019Q2 with an average change of -14.2%.
The average weekly wage is calculated by dividing the total wage for the industry group by the total number of jobs for the industry group and number of weeks in the observed quarter. On the growing industry report, the average weekly wage for electrical equipment and appliance manufacturing (NAICS 335) in 2019Q2 was $1,127.60.
