"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/declining industry is defined as an Industry Group's employment level increasing / decreasing for two quarters by five percent or more over the year. For example, all industries that grew/declined in employment by at least five percent from 2018Q3 to 2019Q3 and subsequently from 2018Q4 to 2019Q4 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 new QCEW becomes available, growing/declining industry information is updated. Only subsector employment sizes of 100 or more are included in these lists. Consequently, 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 52.5% (124 jobs) over the year in 2019Q4 and by 53.2% (123 jobs) over the year in 2019Q3, thus qualifying as a growing industry for 2019Q4. The average growth rate for 2019Q3 and 2019Q4 for NAICS 335 was 52.9%. The declining industry report reads the same way, except with negative changes and therefore, declining industries.
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 2019Q4 was $1,192.61.
