     Heterodata download standard). Each value traces to a real BLS / BEA / Federal-Reserve source;
     nothing is fabricated. The interpretation-labeled heterodox series are a real-competition
     reading of the official data — see <a href="/methodology">Methodology</a> for how the
     constructed series are built.</p>
