This data comes from the Federal Reserve Bank of St. Louis (FRED). It represents average U.S. consumer prices per pound for whole fresh chicken (series ID: APU0000706111) and per dozen for Grade A large eggs (series ID: APU0000708111), normalized to their respective 1980 values. The chart uses national-level monthly data from January 1980 through the most recent available update. Prices are shown on a logarithmic scale to better illustrate proportional changes over time.
Notable context includes periods of volatility in egg prices due to avian flu outbreaks (notably in 2015 and again in 2022–2023), while chicken prices followed a steadier trajectory aligned more closely with overall food inflation.
