Finding Work That Actually Works for You - Day #2

Day 2 - HUZZAH

We continued on to actually accessing the data and validating that it is indeed queryable. Because if it wasn’t, that would suck.

I added an validation step that queried the BLS API for each constructed series ID and inspected the response before ingestion.

No transformations yet, just wanted to make sure I could capture it as given with a focus on the fields I actually need.

Today’s observations;

  • Some series did not exist in the format I assumed (Very helpful readme docs on the gov site clarified this)
  • The API will happily succeed while still giving you empty data. (Thanks for nothing)
So it’s important to note in my captain’s log that JOLTS and ACS describe different things, even when they both fall under labor data.

Let’s define them.

  • Job Openings and Labor Turnover Survey (JOLTS) data is the literal movement of the labor market (hires, quits, separations) aka the churn of the labor market.
  • Series - the numerical sequences assigned to variables (the hires, quits, separations) for each industry.
  • American Community Survey (ACS) data is census data that reflects the market broken down into a demographic container of population, labor force size, employment counts
Then, I had to make a decision, because my initial queries weren’t as robust as I thought I had to pivot. Instead of going granular with industry level data (doesn’t exist), I went national level instead because that data appears more stable and has better continuity.

Therefore, where do we stand now ?

  • JOLTS national rates ingested, validated, and stored cleanly (2022–2024)
  • ACS national context ingested separately, validated and stored cleanly (2022- 2024)
  • Raw tables to preserve original resolution and document “missingness”

Okay. Time for hot chocolate & bed. Good night.
