Today, we’re revisiting Longitudinal Employer-Household Dynamics (LEHD) data, produced by the Center for Economic Studies at the U.S. Census Bureau through the Local Employment Dynamics (LED) Partnership. We’ve used this data before to share maps on the place of residence for Central Corridor workers, major St. Louis City job sectors, jobs per capita in the St. Louis region, and worker commuting patterns in St. Louis City.

This data set uses Unemployment Insurance earnings data, the Quarterly Census of Employment and Wages (QCEW) data, additional administrative data, and census and survey data to provide census-block-level information on where people live and work. You can access LEHD data sets here.

These maps were created using OnTheMap, a Census Bureau software application that’s powered by LEHD data. OnTheMap is free and easy to use. It allows users to create, view, print, and download maps, profiles, and reports related to workforce information, transportation, and economic development. You can read more about OnTheMap here.

The maps and charts below were compiled using Paired Area Analysis reports on primary jobs in 2014. LEHD defines a “job” as “a link between a worker and a firm at which the worker has been employed during the reference quarter and during the quarter prior to the reference quarter. The reference quarter is Quarter 2 (April-June) of the year of interest.” A “primary job” is defined as “the highest paying job for an individual worker for the year.”

OnTheMap allows users to import custom geographies for maps and reports using KML, GPS, or SHP files. The maps below break the City of St. Louis up into three sections: North City, South City, and the Central Corridor. As we’ve discussed in previous posts, the Central Corridor’s boundaries aren’t officially defined, but it generally covers the area between Downtown and Clayton along Interstate 64.

The first three maps examine the characteristics of workers that hold primary jobs in the Central Corridor and live in another specified geography within the city: North St. Louis City, the Central Corridor, or South St. Louis City. Worker characteristics include age range, wage range, and job industry. Job industry classifications (as defined by the North American Industry Classification System, NAICS) are simplified into three main buckets:

  1. Goods Producing: NAICS sectors 11, 21, 23, and 31-33
  2. Trade, Transportation, and Utilities: NAICS sectors 22, 42, 44-45, and 48-49
  3. All Other Services (includes Information, Finance, Professional Services, Management, Real Estate, Education, Health Care, Arts, Accommodation and Food Service, and Public Administration): NAICS sectors 51, 52, 53, 54, 55, 56, 61, 62, 71, 72, 81, and 92

 

There are some notable similarities among these three maps. Workers that live in all three areas, for example, are overwhelmingly employed in the “All Other Services” industry bucket, probably thanks to the Central Corridor’s concentration of professional, health care, and technology-related jobs. There’s also some overlap between areas of high job concentration, with dark clusters in the Central West End around BJC HealthCare and Cortex. But there are some striking differences:

Location

  • Central Corridor workers who live in North and South City appear to be less heavily concentrated in the Central West End than those who live in the Central Corridor. In particular, North City residents have several large clusters of job concentration in the Downtown area.

Age

  • Workers who both work and live in the Central Corridor are more likely to be 29 years or younger (27.9%) than those who live in North (20.3%) or South City (22.3%).
  • Similarly, Central Corridor workers who live in North City are the most likely of all three areas to be 55 or older (23.6%, vs. 19.7% in the Central Corridor and 19.6% in South City).

Earnings

  • The most common wage range category among Central Corridor workers living in North City is the middle category, $1,251-$3,333 per month (51.0% of workers).
  • Among Central Corridor workers who live in South City and especially the Central Corridor, the most common wage range category is $3,333. In South City, 44.2% of Central Corridor workers fall into this range; in the Central Corridor, 47.9% do. By contrast, only 20.6% of North City residents working in the Central Corridor make more than $3,333 per month.

How do these findings compare to Central Corridor workers living in St. Louis City versus St. Louis County at-large? The two maps below take a look:

 

 

The areas of high job concentration look somewhat similar among workers living in the City and the County. As before, though, there are some differences worth noting:

Age

  • Central Corridor workers who live in St. Louis City are more likely to be 29 years or younger (23.3%) than workers who live in St. Louis County (17.6%).
  • Similarly, Central Corridor workers living in St. Louis County are more likely to be 55 years or older (24.8%) than workers living in St. Louis City (20.4%).

Earnings

  • There’s a more even income distribution among Central Corridor workers who live in St. Louis City, where roughly 40% of workers make either $1,251-$3,333 per month or more than $3,333 per month.
  • By contrast, workers living in St. Louis County are much more likely to earn more than $3,333 per month (55.8%) than $1,251-$3,333 per month (29.7%).

Industry

  • Although the “All Other Services” industry bucket is by far the biggest employer of all three categories for Central Corridor workers living in both St. Louis City and St. Louis County, St. Louis County has a larger share of workers in Trade, Transportation, and Utilities (9.2%) than St. Louis City (6.0%), and a slightly larger share of workers in Goods Producing (4.3% versus 3.0%).
