Reading the Illinois Life Score

Illinois's composite score of 51.3 out of 100 — earning a grade of D — places the state at rank #25 of 51 in the national file. The composite is a weighted roll-up of seven dimensions: Cost of Living (20%), Wages (20%), Rent (15%), Safety (15%), Schools (10%), Childcare (10%) and Environment (10%), each normalized to a 0-100 percentile scale. Because the weights are fixed, the state composite is driven more by how the cost and wage dimensions score than by any single other input — a state with strong cost and wage percentiles can absorb mid-tier scores on schools or environment and still land a high overall grade.

In Illinois, the dimension readings are Cost of Living 36/100, Wages 70/100, Rent 72/100, Safety 54/100, Schools 54/100, Childcare 32/100, Environment 26/100. Dimensions where the score sits above 60 indicate the state is in the upper half of the national distribution on that input, while scores below 40 point to structural gaps that a state-level policy or geography cannot easily swap out. The strongest input for Illinois is Rent at 72/100, which carries 15% of the composite weight. The weakest input is Environment at 26/100, carrying 10% of the composite — the drag this adds to the overall score is mechanical, not a ranking artifact.

State-level scores average urban, suburban and rural geography within Illinois, so the readings above should be treated as a state baseline rather than as a readout for any specific metro or county inside the state. Metros inside Illinois are scored separately on the metro pages using the same seven-dimension framework, and individual metros routinely land one or two grades above or below the state composite depending on their local cost, wage and safety profile. For a household weighing a move into or inside Illinois, the state score is best used as a filter — states that grade below C often rule themselves out on cost-of-living or safety alone — while the metro-level pages remain the right tool for the final decision. All underlying data traces back to BEA, BLS, HUD, FBI, NCES, DOL and EPA on the dimension indicated.
