New Jersey - Industry vs. Industry Structure & Performance: Employment Across Counties and Regions for Selected Industries
New Jersey

Introduction & Summary

Pair and compare two distinct average earnings per job industry sectors of your choosing to examine their relative importance and performance across all of New Jersey's 21 county economies over 1969-2016. Contrast and assess, for example, the comparative importance of average earnings per job for the Wholesale Trade sector across the counties of New Jersey against State Government, or any other two sectors you elect to select.
Apply the interactive tools included in this module to conduct your own research about how any two industry sectors compare and contrast across the counties of New Jersey. The analytical tools at your disposal for ranking and sorting the importance and growth of individual industry sectors across counties include: percent of the overall State average earnings per job, percent of the State counterpart, percent of the national counterpart, growth rates and growth rates differenced against overall averages locally and their counterparts nationwide.

Additional Notes on Average Earnings Per Job

Average Earnings Per Job are computed by dividing BEA industry earnings estimate by BEA total full- and part-time jobs estimates. No convenient or adequate means exist at the county or regional level for converting the job estimates to a full-time equivalent measure. So, interpret the average earnings per job estimates with caution in consideration of the following issues:
  • Average earnings per job within industries involving more part-time work is lower than industries involving more full-time work, although there could be little difference in the underlying wage of full-time workers. Such differences could also prevail between counties and regions. An increase in the proportion of part-time jobs over time may erode average earnings per job estimates, although full-time earnings per worker may have remained unchanged
  • As with per capita income, average earnings per job may be subject to extreme short-run variation, especially in smaller counties. Unusual conditions such as droughts, hurricanes and bumper crops give rise to wide variations in average earnings per job. Also, major construction projects relating to building dams, nuclear power plants, and private plant construction projects have caused extreme fluctuations in many smaller states. Such changes typify both small and large agriculture-dependent counties and regions owing to the extreme annual variations in farm incomes.
  • Since average earnings per job are just a simple average, it does not account for variations in the distribution of earnings among high- vs. low-wage jobs.
  • The earnings by major industry estimates compiled by the Bureau of Economic Analysis (BEA) are by place are the sum of wage and salary disbursements (payrolls), supplement to wages and salaries, and proprietors' income. The 2016 earnings by industry data are in expressed in thousands of current dollars ($1,000s). Unlike wage and salary disbursement, it should be noted that proprietors' income may be reported as negative for those years in which the net income of sole propietor and partnerships are in the red for a particular sector. This is not an especially unusual occurrence in some relatively small counties where farm proprietorships are dominant. However, this may yield some somewhat unconventional results, such as an industry recording a negative share of total earnings or a location quotient that is negative.
