How to Read the Laundromat Market Data on This Site

What does each source measure?

Sources: Census CBP and ACS; BLS QCEW; EIA State Electricity Profiles. The source year describes the measurement period, not when a page was last edited. A historical figure should retain its label after publication.

What does NAICS 812310 cover?

NAICS 812310 covers businesses primarily operating facilities with self-service laundry and drycleaning equipment for customers. It is narrower than all drycleaning businesses. The classification does not tell you whether a store is attended, its machine count, its hours or its financial performance.

CBP adds a separate coverage restriction: it describes establishments with paid employees. A business with no paid employees is outside that universe. An unattended store can still employ cleaners or maintenance staff, so attendance is not the inclusion rule. Conversely, owner-operated does not necessarily mean nonemployer.

The two limits must be kept separate. It is incorrect to treat the reported total as either a guaranteed minimum or maximum for all laundromats. A geographic comparison is informative only to the extent that classification, employer coverage and boundaries are comparable. Applying one classification to two markets does not prove that their coverage bias is equal.

How should uncertainty and missing values be read?

ACS estimates come from a sample. The published margin of error helps assess precision; a small apparent difference may not establish a meaningful difference between places. The geographic tables display the published population, renter-household and income margins where available. The site does not calculate a combined margin for every ratio or prove statistical significance for rankings.

Do not mix one-year and five-year ACS releases in a table without clearly identifying them. They cover different periods and can give different answers for the same city. The current geographic build uses the explicitly named ACS 2020–2024 five-year release and keeps its source URLs and retrieved snapshot.

A blank or missing match is not a zero. It also is not automatically evidence of suppression. Publication rules, industry coverage, boundary matching and source availability can all affect a result. Check the original record and flags before deciding which explanation applies. The site should not infer hidden establishments or assign an invented value to a missing cell.

What do the geographic ratios mean?

Renter households per employer establishment divides an ACS household estimate by a count from a different program and reference period. It is a descriptive ratio. It does not measure the number of households seeking commercial laundry, because neither in-unit machines nor building laundry rooms are in the numerator. It does not measure machine capacity in the denominator.

A high ratio is therefore a reason to investigate laundry access and competitors, not proof of an underserved market. A low ratio cannot prove saturation. No mechanical conversion turns either ratio into expected turns, a valuation premium or the number of buyers who will pursue a listing.

A BLS establishment location quotient answers another question: how large the industry's share of the local establishment base is relative to its national share. It does not contain population, laundry demand or machine capacity. County location quotients cannot be averaged into a valid multi-county quotient without the appropriate denominators.

Why are ZIP estimates not city totals?

Postal ZIP codes are assigned for mail delivery. Census ZCTAs approximate their spatial distribution but are not the same geographic system. This site's ZIP screen matches postal industry records to ZCTAs that have at least half their land within a city, using the published Census relationship file.

That land-area rule is a screening convention. It can include businesses outside the city when a selected ZIP crosses the boundary, and omit businesses inside the city when their ZIP does not meet the rule. It follows that the result is neither an exact city total nor a firm lower bound. Dividing the whole city's population by that partial postal count creates a boundary mismatch, so the geographic pages do not present it as a city saturation measure.

The useful output is a list of postal areas to investigate. Confirm store addresses and operating status, then draw a catchment based on actual travel and customer behavior. A postal area with no matched industry record still needs field verification.

How should payroll benchmarks be used?

QCEW weekly wages reflect covered workers across the industry and include different jobs and working hours. They are not an occupational quote for an attendant. Multiplying a weekly average by the number of weeks in a year is an annualized illustration, not proof of a full-time salary or a measured saving from eliminating a position.

CBP annual payroll divided by its employment measure is also contextual. Its reference concepts differ from QCEW, so differences between the series should not be described automatically as business openings, closures or errors. The staffing budget still requires roles, scheduled hours, rates, overtime and employer costs.

Similarly, comparing one worker's industry pay with median household income cannot establish whether that worker supports a household or will leave the job. A household may have multiple earners, different work hours and other income sources.

What evidence turns a screen into a decision?

Use the site-selection guide to organize field work. The market report and operating benchmarks describe different evidence: reported sales and survey respondents. Neither should be blended with employer counts as though all three measured the same population.

For an offer or asking price, move from this geographic screen to store-level valuation. For a disputed figure, the editorial policy explains what to send with a correction request.
