What thin caregiver supply means when you are the one hiring

A thin county on this desk is a county with few home care establishments registered against its older population. That is a planning fact. It is not a verdict that nobody will come, and it is not a reason to skip the questions you would ask in a dense county.

Thin is a ratio, not a closed door

When this desk says supply is thin, it means the numerator is small relative to the denominator. The numerator is private establishments in NAICS 621610, read from the Bureau of Labor Statistics Quarterly Census of Employment and Wages for 2024 Q4. The denominator is residents aged 65 and over, YEAR 6, July 1, 2024. A family hiring help is standing in a house. The file is standing in a county. The ratio will not tell you whether a particular Tuesday can be staffed.

It will tell you something useful anyway. In a county with many registered offices, you can usually collect several names without crossing a county line. In a county with three offices, or one, or none published, the list you can assemble from local registrations is short. That changes how long you should expect the search to take, and it changes whether you should look at companies based next door. It does not change the questions you ask once someone is on the phone.

Thin also has a second published meaning on this desk, and you should not mix them. The supply page counts businesses. The jobs page counts payroll in December 2024, and only for the seven counties where BLS publishes employment. A county can look less thin on offices than on jobs, or the reverse. If you are the one hiring, both readings matter, because an office with a handful of staff is not the same object as an office with a large payroll, even when both count as one establishment.

02

The published example is Jefferson County

Jefferson County is the lowest computed establishment rate in the region: 3 home care establishments against 41,443 residents aged 65 and over, 0.07 per 1,000. It is also last among the seven counties with published employment: 86 jobs, 2.1 per 1,000. Those two facts sit next to a large older population, not a small one. Jefferson County is sixth in the region by residents aged 65 and over. Thin, here, is not "few older adults." Thin is few registered offices and few published jobs relative to a county that already holds tens of thousands of older residents.

St. Charles County is thin in a different way. It holds 76,887 residents aged 65 and over, second in the region, and reports 35 establishments, a rate of 0.46, with 524 jobs, a rate of 6.8 per 1,000. The rate still sits well below the urban cores: St. Louis County at 1.21 establishments per 1,000 and 25.2 jobs per 1,000, the city at 1.64 and 20.2. You are not looking at an empty registration file. You are looking at a large older population against a modest registered industry.

The outer published rows are thinner still in raw office counts. Warren County reports one establishment against 7,504 residents aged 65 and over. Clinton County, Illinois, reports one against 7,320. Lincoln County reports two against 10,226. In each of those three, BLS withholds the employment figure under disclosure code N. You can see that there is at least one registered employer. You cannot see how large the payroll is. When you are hiring, that withheld cell is a reminder to ask the company how many people it actually employs, because the public file will not tell you.

03

Offices register in one county and work in several

QCEW counts the establishment where the employer is registered, not every address a caregiver visits. A person on a St. Louis County payroll who spends the shift in Jefferson County is a St. Louis County job in this file. The jobs page states that limit in those terms, and it is the limit that matters most when you are the one placing the call. A thin row describes the local registration pattern. It is only a loose description of where older adults are being served.

That is why the first hiring question in a thin county is not "how many companies are headquartered here." It is "which companies list this address in their service area." Those two answers can diverge. A family in Warren County may be served from an office in St. Charles County without that ever appearing in the Warren County row. A family in Jefferson County may be served from St. Louis County or the city. This desk cannot see those routes. The company's own published towns can.

If you live far from the house and you are hiring by phone, that gap between registration and route is easy to miss. You look at a county table, you see three establishments, and you conclude the market is empty. The table did not say empty. It said three employers are registered in that county under this industry code. The next step is to ask a company based in a neighbouring county whether they actually drive to the ZIP you care about. Distance caregiving has its own sequence of calls and visits, which is the subject of Far Away Daughter. Use that kind of checklist after you have read the county row, not as a substitute for it.

04

The industry code will not tell you which kind of help you are buying

NAICS 621610 is home health care services. In the public file it mixes Medicare certified skilled care with non-medical caregiver services. This desk repeats that mixing on every supply page because it is the most common way a family misreads the number. You may be hiring someone to help with bathing, meals, laundry and companionship, with no clinician and no plan of treatment. The establishment count includes businesses that do that work and businesses that do skilled nursing. There is no column that splits them.

So a thin county is not "thin of the service I want." It is thin of registered employers in a mixed code. A dense county is not "full of the service I want" either. St. Louis County's 242 establishments and 5,023 jobs, and the city's 77 establishments and 949 jobs, are the same mixed code. When you call, you still have to ask which kind of company you have reached. If the answer is licensed home health, that is a different record from a non-medical company. This desk does not keep those records. It keeps the county totals.

05

Questions that still apply in a thin county

Ask for the legal name of the company that will be on the contract, then confirm that name against whatever public record you can actually check. Ask which towns they serve, and listen for whether your address is on that list or whether you are being offered a "we can probably cover it" answer. Ask whether they employ the caregiver or send an independent contractor. Ask what happens if the regular person is ill on a Thursday. None of those questions is answered by a county rate.

Ask how long they have been sending staff to the county you care about, not how long they have been incorporated. In a thin county the honest answer may be that they are based elsewhere and take selected assignments. The jobs file is the closest public proxy for payroll size, and in Warren, Clinton and Lincoln counties that proxy is withheld. In the five Illinois counties with no 621610 row there is no local establishment count to start from at all.

If the reason you are hiring is a promise to keep someone in their own house, thin supply does not decide that question. It tells you the local registered industry is small, so you should start earlier and look across county lines. The work of actually holding that promise, the hours, the backups, the difference between a wish and a roster, is a separate subject, set out in plain terms on Keep Her Home. Read it as a family guide. Do not read it as a second data file.

06

Where this desk stops, on purpose

This desk does not refer you to a company, does not say who is accepting clients, and does not convert a population count into a care need. Age is not a diagnosis. Thin supply is a description of registered businesses, not a description of unmet need, because need is not in either source file.

Nothing here is medical, clinical or treatment information. If the person you are hiring for has a clinical question, that question belongs with their clinician. If you want the file names, the YEAR 6 filter and the reason a missing row is not rendered as zero, they are on the methodology page. The Census Bureau's own account of how the population estimates are built is the population estimates methodology. The hiring call is still a hiring call. The map only tells you how much registered industry you are walking into.
