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.本数据集所有序列均仅取自官方及公开来源。其中建筑业国内生产总值、国内生产总值总额、固定资本形成总额（Gross Fixed Capital Formation, GFCF）及公共消费相关序列，均来自巴西地理与统计研究所（Instituto Brasileiro de Geografia e Estatística, IBGE）的季度国民账户（SIDRA）；Selic利率（Selic Rate）相关信息提取自巴西中央银行时间序列管理系统（SGS），并汇总为季度均值。所有序列均已转换为实际值，按季度统一口径，并采用X-13 ARIMA-SEATS方法完成季节调整。
