← The economy

Economics — localized baseline

What Champaign County, Ohio's economy actually is, quantitatively — the ground the data-center deal sits on. Employment by industry for 2023 (BLS QCEW) with each sector's location quotient (county share ÷ national share), and population (US Census ACS). The employment and population figures are connector-sourced [verified], with each sector's location quotient derived from them; the prose companion is Economics — demand & public benefits.

Consumer energy costs

What households in Ohio pay for electricity and heating fuel — the consumer-price half of the demand thread the data-center load presses on. State-level EIA residential prices and retail sales, each connector-sourced [verified], charted over the last ~quarter-century (the natural-gas series reaches back to 1967, but the window is trimmed for legibility). Prices are in native units — electricity in cents/kWh, gas in $/Mcf, sales in million kWh.
