Base Macro Quarter 2002-2025

Obtained exclusively from official and public sources, the series on construction GDP, total GDP, GFCF, and public consumption come from the IBGE's Quarterly National Accounts (SIDRA). Information on the Selic rate was extracted from the Central Bank of Brazil's Time Series Management System (SGS) and aggregated to quarterly averages. All series were converted to real values, harmonized on a quarterly basis, and seasonally adjusted using the X-13 ARIMA-SEATS method.
