Which index should you use?
CPI-U is the standard measure for purchasing-power questions and the one used for most cost-of-living comparisons. Core CPI excludes food and energy and is smoother, but it is not what households actually pay. PCE (Federal Reserve's preferred gauge) starts in 1959 and uses a different basket and formula. All series here are shown not seasonally adjusted, the form used for contract and cost-of-living adjustments. Details on the methodology page.
