I’m trying to understand how economists think about transport and freight data relative to more popular indicators like market sentiment, equity performance, or business surveys.
For example, China reported that Q1 commercial freight volume rose 4.1% year-on-year. Intuitively, that seems like a meaningful signal about logistics demand and industrial throughput. But how should economists treat this kind of number? Is it usually considered a leading indicator, a confirming indicator, or something more limited and sector-specific?
I’m especially curious because freight activity feels more “real economy” than sentiment-based data, but I’m not sure how much weight professionals usually place on it.
Why can freight and transport data sometimes be more informative than market sentiment when judging real economic strength?

For me, they are secondary indicators, that are used to support broader major indicators (employment, wages, production, prices).
They aren’t enough to really declare anything by themselves (or in tandem), but I generally use them to confirm with other indicators.
My department does a quarterly econ pub for a major MSA in CA. We use several secondary indicators as “robustness checks”, to further justify where we think things are headed.
So, still highly important. You’re just not driving conclusions off of them alone.
