Home / Automotive repair & maintenance / New York / Suffolk County, NY
How many auto repair exist per person present — residents plus daytime workers — by ZIP code, compared with the U.S. average. Establishment data: Census ZBP 2023. Population: ACS 2024 5-year. 110 ZIP codes analyzed.
Includes: Auto repair & maintenance shops · Body, paint & interior repair. Counted together because official statistics use one 811121 code.
Why a range: Census does not publish a ZIP-by-industry count when that ZIP has 0–2 businesses. 78 ZIP cells in this county are withheld, 74 of them with residents. Each could hold 0, 1, or 2 businesses: counting them all as 0 gives the low end, counting them all as 2 gives the high end — the data cannot say where the truth sits. The density range uses only the populated cells, since ZIPs without residents are excluded from per-person rates. How ranges work
230 auto repair are counted in Suffolk County — 1.3 per 10,000 people present (residents + daytime workers), 153% of the U.S. rate of 0.9.
On the comparable ZIP set (ZIPs with a published count in every year), the total has stayed roughly flat between 2015 and 2023 (205 → 205).
Measured supply density is highest in 11729 (Deer Park), 11705 (Bayport), 11757 (Lindenhurst) — well above the national rate. On measured density alone, the lowest-density residential ZIPs with a published count are 11901 (Riverhead), 11725 (Commack), 11720 (Centereach).
BLS QCEW puts the latest county-wide count (2026 Q1) at 256 establishments, the freshest available signal.
Measured density: Suffolk County sits at 153% of the U.S. rate for auto repair. 74 ZIPs with population have no published count (each 0–2 businesses), so the true per-capita rate is between 153% and 252% of the U.S. rate. Why. The highest measured density is in 11729 and 11705; the lowest measured density is in 11901 and 11725.
This is a supply-side read: it counts existing auto repair and the people present, not foot traffic, income, rent, or whether locals want more. Treat low density as a question to check, not an answer.
Suffolk County had an estimated 1,535,909 residents on July 1, 2024 — 0.9% more than in 2020 (+13,734). In the latest year it gained 6,880 people: births minus deaths +3,394, international migration +9,881, domestic migration −6,469. Components are published separately and may not sum exactly.
639,110 jobs were located in the county in 2022 (−3.7% since 2019), and 768,254 employed residents lived there (+0.1% since 2019). LODES counts wage and salary jobs covered by unemployment insurance plus federal jobs; it excludes the self-employed and military, and counts jobs rather than unique people. 2019→2022 spans the pandemic, so read it as one change, not a trend.
Population and migration say whether the customer base is growing. They do not say whether people want another business of this type. Definitions and limits → · Full county detail →
ACS 5-year estimates for 2015–2019 and 2020–2024. Only ZIPs with at least 2,000 residents in both windows and a change larger than the survey margin of error (90%) are listed — small ZIPs move a lot on paper without a real signal.
Not shown. Census publishes only a broader group that also includes auto glass shops, so an auto-repair-only nonemployer count is not published.

White dots are ZIP totals from the official Census count — the bigger the dot, the more auto repair in that ZIP. They are aggregated, not individual shops. Turquoise dots are individual locations mapped in OpenStreetMap, shown only at street level; they are crowd-sourced and indicative, may be incomplete, and do not equal the official counts. Only the official ZIP totals feed the saturation index.
Number of auto repair in Suffolk County across 2015–2023, on a consistent set of ZIP codes present in every year — so changes are real, not ZIP-boundary artifacts. 2015/2018 are pre-pandemic baselines; 2020/2021 are COVID-distorted.
These ZIPs have far more workers (or visitors) than residents, so their counts are driven by daytime and visitor demand — not a place to read "shortage" from resident numbers alone.

The numbers above tell you how the market looks. To find a specific storefront, these marketplaces list available retail space for lease.
Open vacancy data (actual empty units) is only published by some cities; where it exists we show it directly. Listings above are third-party.
Census withholds some ZIP-by-industry cells to protect small businesses. 0–2 means the cell was not published (Census publishes industry counts only at 3+ per ZIP), so the ZIP is left unranked rather than counted as zero. ~ means the count is estimated from the broader industry group and can be off by a business or two.
When a data vintage changes or a section of this report is revised, we post it to a public update feed. No email address, no account, no tracking — and nothing is sent unless something actually changed.
Establishments. U.S. Census ZIP Code Business Patterns (ZBP 2023), NAICS 811121 — automotive body, paint & interior repair. Counts establishments with paid employees. ZBP is published annually with a ~2-year lag.
Fresh county signal. BLS QCEW (quarterly) is newer than ZBP — 2026 Q1 shows 256 establishments county-wide for this industry. It cannot be broken down by ZIP.
Population. U.S. Census American Community Survey 2024 5-year ZCTA population (table B01003). Workers are the ZIP's total employment from the same 2023 ZBP file.
Demand ("people present"). Demand comes from residents and daytime workers: residents + 0.5 × workers. This is the single documented assumption in the model and can be tuned.
Index. index = (ZIP establishments ÷ ZIP demand × 10,000) ÷ the U.S. average for this industry (0.87 per 10,000 present). It is a supply-side density measure; it does not capture income, rent, tourism, or whether locals actually want more.
BizGapMap — free, no-login small-business saturation reports for major U.S. counties. Built entirely from public U.S. Census, BLS, and IRS data (ZBP 2023, ACS 2024 5-year, PEP 2024, LODES, QCEW, IRS SOI). No forecasts, no revenue guesses — withheld cells are marked, and the few derived counts are labelled as estimates.
