Strengths

Weaknesses

What changed in five years

How each measure moved between two periods about five years apart, read against whether more or less is better, the published margin of error and the same change in other places.

States like Illinois five years ago that improved

The places whose measures looked most like those of Illinois in the earlier period, ranked by how many measures improved beyond the margin of error, minus how many declined. A comparison of published data, not a forecast and not advice.

Who lives here

Age, race and education of residents, from the American Community Survey. Shares are of all residents (age), residents of every origin (race) or adults 25 and over (education).

Income

How household income is spread, not just the middle: each bar is the share of households in that income range.

Homes

Who owns and who rents, what homes cost, and what the housing stock looks like.

Getting to work

How workers travel to their job and how long it takes them.

Jobs and pay

What the largest occupations here pay, from the Bureau of Labor Statistics' Occupational Employment and Wage Statistics survey.

Local businesses

Employer businesses and sole proprietors by industry, per resident and against the state and the nation. Counts of businesses next to counts of people, not a measure of demand.

Federal contract spending

Federal grants & assistance

Grants, loans (counted at their subsidy cost), direct payments and insurance, by fiscal year of the action (USAspending.gov, FABS). Reported apart from contracts and never added to them.

Public money & outcomes

Federal money per resident by fiscal year next to how the place changed, and, when its money jumped, how it compares with similar counties. A comparison, not cause and effect.

Representation in Congress

Members serving today, with their record in the current Congress (party-unity votes cast with their caucus, roll calls missed). Not a grade.
