States like Delaware five years ago that improved
The places whose measures looked most like those of Delaware 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).

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.

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.

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.
