Where Do I Find Official Population and Labor Data for Thumb Counties?

Grant applications, business plans, school projects, and news stories about the Thumb all eventually need the same thing: a defensible number for population, employment, or wages in a specific county. The internet is full of stale copies of those numbers. Here is where the current, official ones live.

The state's data shop

Michigan's central source for labor market and demographic statistics is the Michigan Center for Data and Analytics. It is the state agency responsible for employment estimates, unemployment rates, industry and occupational data, wage information, and population figures and projections for Michigan and its counties. If you need a number for Huron, Sanilac, Tuscola, Lapeer, St. Clair, Shiawassee, or Genesee County, this is the front door: the figures there are the same ones state government itself uses.

A few habits make the data more useful:

• Note the vintage. Every table has a reference period. A county unemployment rate is for a specific month; a population figure is an estimate for a specific year. Quote the number with its date.
• Distinguish estimates from counts. Between decennial censuses, population figures are estimates, revised as better information arrives. Two documents citing different numbers may both have been right when written.
• Use the county, not the region, when precision matters. "Thumb Region" totals are usually someone's sum of county figures. For anything formal, cite the county-level data and do the arithmetic transparently.

Regional analysis that is already done

If you need interpretation rather than raw tables, two organizations publish regional analysis for this area. The East Michigan Council of Governments produces regional planning and economic development documents for east-central Michigan — the kind that federal economic development programs require — and these typically compile county data into a regional picture with commentary. For business-focused questions, the Michigan SBDC's regional office offers market research support to small businesses at no charge, which can save you from wrestling with databases yourself.

Matching the number to the question

A quick translation table between common questions and the right kind of source:

• How many people live in this county? — Population estimates via MCDA.
• What is unemployment like there? — Local area unemployment statistics, also via MCDA, always with the month attached.
• What do jobs in a given industry pay locally? — Occupational and wage data through MCDA.
• What is the region's economic strategy? — EMCOG's planning documents.
• Is there a market for my business idea here? — Start with SBDC counseling rather than raw data.

The general rule: never quote a regional statistic you found on a secondhand website — including this one, which is why this page gives you sources instead of figures. Go to the agency, take the current number, and write down when and where you got it.
