Lake County, IL — Auto repair Saturation

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. 32 ZIP codes analyzed.

Includes: Auto repair & maintenance shops · Body, paint & interior repair. Counted together because official statistics use one 811121 code.

Measured density: Range spans bands — 0.85× the U.S. rate (between 0.85× and 1.28× once withheld ZIP cells are counted)

Why a range: Census does not publish a ZIP-by-industry count when that ZIP has 0–2 businesses. 20 ZIP cells in this county are withheld, 17 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

Range spans the U.S. rate   Lake County auto repair — 85–128% of the U.S. rate

68 auto repair are counted in Lake County — 0.7 per 10,000 people present (residents + daytime workers), 85% of the U.S. rate of 0.9.

On the comparable ZIP set (ZIPs with a published count in every year), the total has fallen 11% between 2015 and 2023 (76 → 68). That set is smaller than today's county total. 2020–2021 were pandemic-distorted, and Census rounds counts, so small moves are within noise.

Measured supply density is highest in 60044 (Lake Bluff), 60042 (Island Lake), 60084 (Wauconda) — well above the national rate. On measured density alone, the lowest-density residential ZIPs with a published count are 60030 (Grayslake), 60046 (Lake Villa), 60073 (Round Lake).

BLS QCEW puts the latest county-wide count (2026 Q1) at 73 establishments, the freshest available signal.

Measured density: Lake County sits at 85% of the U.S. rate for auto repair. 17 ZIPs with population have no published count (each 0–2 businesses), so the true per-capita rate is between 85% and 128% of the U.S. rate. Why. The highest measured density is in 60044 and 60042; the lowest measured density is in 60030 and 60046.

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.

Lake County had an estimated 718,604 residents on July 1, 2024 — 0.7% more than in 2020 (+5,178). In the latest year it gained 4,397 people: births minus deaths +1,664, international migration +7,297, domestic migration −4,601. Components are published separately and may not sum exactly.

325,899 jobs were located in the county in 2022 (−2.5% since 2019), and 328,007 employed residents lived there (−1.0% 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.

Nonemployer businesses

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.

Market trend — down 11% since 2015

Number of auto repair in Lake 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.

Low measured density is not evidence of opportunity. A ZIP with few auto repair may simply lack foot traffic, retail space, or demand. We rank only residential and mixed ZIPs here; employment hubs and visitor destinations are listed separately below. ZIPs where Census did not publish a count (0–2 businesses) are not ranked: they may be the least served of all, but the data cannot tell 0 from 1 or 2. Verify those locally.

Employment hubs & destinations

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.

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.

Methodology & sources

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 73 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.
