Missouri by county: Census 2020–2024

Every adult in Missouri, as the Census counts them, county by county and grouped by metro area. Each person is a real combination of traits from the Census's anonymised person records, weighted so every county matches its published tables, with party lean and 2024 turnout modelled and labelled so.

How close the people land on the Census

Each county's records are weighted until they match its American Community Survey tables. The figure is the worst county's largest gap on each table, in percentage points.

Table	Worst county
Sex by age	0.4
Race and ethnicity	0.4
Education	0.4
Household income	0.5
Work	0.2
Owned or rented home	0.3
Citizenship	0.0

A check left out of the fit: veterans

Veteran status was not used in weighting, so it shows how well the weighted people carry traits nobody fitted. Per county, the share of veterans among civilian adults lands a median 0.7 points from the Census's own figure; 95% of counties within 3.4, the worst 9.0.

What drawing a population adds

A population is a sample of these weighted people, so small counties vary from draw to draw. Largest gap per county between the people drawn and the county's records, counties with at least 30 people.

Trait	10,000 people		100,000 people
	Median	95% of counties within	Median	95% of counties within

Household income	2.1	4.6	0.5	1.9

Party lean and 2024 turnout (modelled)

No Census record says how anyone votes, so these two traits are modelled. Each person starts from what Cooperative Election Study 2024 respondents like them (race, age, education and sex, in the Census Midwest) said and did, with turnout checked against the voter file. Each county is then calibrated so its people's turnout and Democratic-minus-Republican margin match its 2024 presidential result (MIT Election Lab). Those results count votes for president, so turnout runs a point or so under ballots cast.

Check	Margin	Turnout
Each county against its 2024 result (calibrated)	median 0.0, worst 0.0	median 0.0, worst 0.0
Demographics alone, given only the statewide result	median 29.7, worst 56.9	median 3.1, worst 14.6
The same, with priors that never saw anyone from Missouri	median 29.9, worst 57.3	median 3.0, worst 14.5

Leans against Missouri's own survey respondents

Nothing was fitted to these: the share of each lean among Missouri's adults, as modelled and as the CES's Missouri respondents gave it.

	Democratic	Republican	Neither	Turnout
Model	35%	48%	17%
CES Missouri (n=1,305)	34%	47%	18%
Priors that never saw anyone from Missouri, applied to its 1,300 citizen respondents	39%	43%	18%	58%
CES Missouri, citizens (n=1,300)	34%	48%	18%	62%

The county totals are right by construction: that is what calibration does. The honest test is the people alone, in the table above: given only the statewide result, how far each county's people land from its margin. Counties that vote very differently from people like them elsewhere in the region land furthest; the map shows where.

Within a county, calibration moves everyone's lean by the same factor, so lean by race inside one county is the weakest part. In the smallest counties the Census's five-year estimates carry wide margins, and where more presidential votes were cast than the estimate of citizens, turnout is held at 98%.

Use these traits to include or compare groups. They are not anyone's stated party, and results are never polls of real people.
