INE (Instituto Nacional de Estatística) is Portugal's official statistics office, responsible for collecting, processing, and publishing data on the economy, population, housing, employment, inflation, and social conditions.

Key INE publications include the Consumer Price Index (CPI), quarterly GDP figures, housing price indices, census data, and labor market statistics. These figures are widely used by policymakers, journalists, lenders, and international organizations to assess Portugal's economic and social trends.

INE data is publicly available at ine.pt, where users can access databases, press releases, and interactive tools covering everything from property prices to demographic shifts.
