BLS vs Truflation CPI numbers.
This exact divergence is what makes the current macroeconomic debate so intense—and why so many private investors are pulling their hair out watching the Fed respond to "old" or flawed data.
Right now, the gap between the two is staggering: the BLS has official year-over-year CPI at 4.2%, while Truflation’s real-time index is sitting way lower, down at 1.84%.
Truflation is showing that inflation has essentially been crushed, while the government's data screams that an emergency rate hike is needed. This massive disconnect comes down to how the data is gathered, and the biggest culprit is housing.
The Lag: How the BLS Measures Housing
Housing makes up roughly one-third of the official BLS Consumer Price Index. To calculate it, the BLS uses a metric called Owners' Equivalent Rent (OER).
Instead of looking at real-time home sales or new leases, the BLS literally surveys homeowners and asks a hypothetical question: "If you were to rent your home today, how much do you think it would rent for?"
Because the BLS only surveys these households once every six months, the data takes forever to move.
The BLS Reality: The high inflation numbers we are seeing from the government right now are heavily skewed by real estate and rental spikes that actually happened 6 to 12 months ago. It is a rearview-mirror metric.
The Truflation Reality: Truflation scrapes over 15 million data points daily from real-time sources like Zillow, Trulia, and real transaction data. It captures what someone signing a lease today is actually paying. When real estate cools, Truflation registers it instantly.

The differences stretch beyond housing into how information is physically processed:
