McHenry County, not Crystal Lake

McHenry County context, not Crystal Lake figures

These are McHenry County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Crystal Lake measurements.

  • Establishments in McHenry County8,140
  • Employment at those establishments, McHenry County87,684
  • Covered employment, McHenry County96,922
  • Average annual pay, McHenry County$55,107
  • Average weekly wage, McHenry County$1,060
  • Housing units permitted, McHenry County1,565
  • Of those, single family, McHenry County887
  • County product, 2024, McHenry County$15,982,773,000
  • County product change over the prior year, McHenry County4.6 percent
  • Average income of an arriving household, McHenry County$80,258

Every figure in this section is published for McHenry County as a whole and is not a measurement of Crystal Lake. It is here because a county backdrop is what a credit committee reads a place against, and it is labelled so that it can never be quoted as the place's own.

Coverage

What this page does not hold.

Every item below could be filled with a plausible figure. None of them is. On a page a lender may read, a number that cannot be traced is worse than an absence, so the absences are named.

  • Parcel level detail, zoning and flood zone at an address are resolved in the platform, not on this page.

SBA figures count approvals to borrowers whose address is in the place. They are not approvals for projects inside the place boundary: the tape records a borrower city and a project county, and those can differ.

Common questions

Crystal Lake questions, answered from the record.

How many people live in Crystal Lake, Illinois?

40,579, in 14,806 households. Crystal Lake city covers 18.99 square miles of land, which is 2,137 people per square mile. Source: US Census Bureau, American Community Survey 5-Year Estimates, place level, 2020-2024 5-year.

What county is Crystal Lake in?

McHenry County, which holds 100.0 percent of the place by area. Source: US Census Bureau, cartographic boundary file, places, 2024 vintage.

What is the median household income in Crystal Lake?

$108,418. The median owner-occupied home is valued at $311,400. Median gross rent is $1,468 per month. Source: US Census Bureau, American Community Survey 5-Year Estimates, place level, 2020-2024 5-year.

How much SBA lending goes to Crystal Lake businesses?

81 7(a) approvals totalling $44.8 m, across 29 lenders, median approval $250,000, plus 62 504 approvals worth $40.0 m. These count approvals to borrowers whose address is in Crystal Lake, not projects sited inside the place boundary, and they are approvals recorded in the release rather than loans disbursed.

Do SBA loans to Crystal Lake borrowers get paid back?

Of the 17 loans that have reached a final outcome, 15 were paid in full and 2 charged off, a charge off rate of 11.8 percent. Loans still running are excluded because they have not yet succeeded or failed.

Is Crystal Lake in the National Flood Insurance Program?

Yes. Crystal Lake appears in the FEMA Community Status Book as community 170476, carrying Community Rating System class 6, which is a premium discount for exceeding the programme minimum. Whether a specific parcel sits in a mapped special flood hazard area is an address level question the platform answers.

Are the county figures on this page Crystal Lake figures?

No, and they are labelled so. County Business Patterns, QCEW, the Building Permits Survey, BEA product and IRS migration are published for McHenry County as a whole and there is no place level equivalent. They appear in one clearly marked section as context and are never presented as measurements of Crystal Lake.

Is zoning published for Crystal Lake?

Not yet. The zoning layer is in build. Nothing on this page presents parcel level zoning.
