Tuolumne County, not Columbia

Tuolumne County context, not Columbia figures

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

  • Establishments in Tuolumne County1,266
  • Employment at those establishments, Tuolumne County12,548
  • Covered employment, Tuolumne County18,221
  • Average annual pay, Tuolumne County$58,725
  • Average weekly wage, Tuolumne County$1,129
  • Housing units permitted, Tuolumne County62
  • Of those, single family, Tuolumne County62
  • County product, 2024, Tuolumne County$3,306,314,000
  • County product change over the prior year, Tuolumne County-1.2 percent
  • Average income of an arriving household, Tuolumne County$81,794

Every figure in this section is published for Tuolumne County as a whole and is not a measurement of Columbia. 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.

  • This place is not listed as a community in the FEMA Community Status Book, so no NFIP participation or CRS class is shown.
  • 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

Columbia questions, answered from the record.

How many people live in Columbia, California?

2,235, in 993 households. Columbia CDP covers 5.96 square miles of land, which is 375 people per square mile. Source: US Census Bureau, American Community Survey 5-Year Estimates, place level, 2020-2024 5-year.

What county is Columbia in?

Tuolumne 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 Columbia?

$58,520. The median owner-occupied home is valued at $376,200. Median gross rent is $1,217 per month. Source: US Census Bureau, American Community Survey 5-Year Estimates, place level, 2020-2024 5-year.

How much SBA lending goes to Columbia businesses?

4 7(a) approvals totalling $960,000, across 3 lenders, median approval $340,000. These count approvals to borrowers whose address is in Columbia, not projects sited inside the place boundary, and they are approvals recorded in the release rather than loans disbursed.

Do SBA loans to Columbia borrowers get paid back?

No rate is published for Columbia. only 1 resolved loans, too few to publish a rate, and a percentage over that few outcomes would move several points on a single loan. The counts are shown instead.

Are the county figures on this page Columbia figures?

No, and they are labelled so. County Business Patterns, QCEW, the Building Permits Survey, BEA product and IRS migration are published for Tuolumne 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 Columbia.

Is zoning published for Columbia?

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