WASHINGTON (AP) — Prices paid by U.S. consumer jumped 7% in December from a year earlier, the highest inflation rate since 1982 and the latest evidence that rising costs for food, gas, rent and other necessities are heightening the financial pressures on America’s households. Inflation has spiked during the recovery from the pandemic recession as Americans have ramped up spending on goods such as cars, furniture and appliances. Those increased purchases have clogged ports and warehouses and exacerbated supply shortages of semiconductors and other parts.
