Census metric ranks compare all jurisdictions in this snapshot (typically 50 states plus D.C.). Race and ethnicity categories follow Census definitions (e.g., Hispanic origin is asked separately from race). Percentages are shares of total population and may not sum to 100% because of rounding or other groups. State–local tax burden is not a Census figure; see the Tax Foundation link below for 50-state + D.C. rankings (1 = lowest aggregate burden).
Why this state votes this way
Demographics and long-run trends that commonly shape coverage and turnout narratives.
Illinois's Census profile summarizes population scale, sex composition, race and Hispanic origin, and household income—baseline conditions analysts pair with polling and election returns when they discuss coalitions and regional turnout.
What often shows up in coverage
- Slower population change can stabilize turnout baselines; campaigns may emphasize persuasion and registration efficiency more than rapid expansion of the voter pool.
- A sizable Hispanic or Latino population (17.8%) is regularly cited when describing growing suburban diversity and swing precinct strategy.
- Demographic profile at a glance: White, non-Hispanic residents are about 59.6% of the population in this ACS snapshot, a baseline often used to frame coalition math and statewide messaging priorities.
These indicators are descriptive context for understanding electoral environments—they do not predict vote shares, winners, or partisan realignment.

Context & notes
Democratic bulwark driven by Chicago and its suburbs, with downstate areas providing most of the Republican presidential vote.
