Prices: Comparative price levels (Edition 2021)

This dataset contains monthly comparative price levels (CPL) which are defined as the ratios of purchasing power parities (PPPs) for private final consumption expenditure to exchange rates. They provide measures of differences in price levels between countries. The monthly PPPs used to derive the table are OECD estimates obtained by extrapolating 2011 PPPs for private final consumption expenditure using the relative rates of inflation between the countries as measured by their consumer price indices.
