THE SHORT ANSWER
What the number can—and cannot—say.
This is a population statistic, not a dating-pool count
The headline covers U.S. adult women regardless of marital status, orientation, location, or whether they are dating. Those additional conditions are outside the CDC height statistic.
Cutoffs need distributions, not just an average
An average alone cannot tell you what percentage clears a chosen height. The calculator uses the CDC percentile distributions by age decade, then keeps the physical-trait estimate separate from joint Census counts.
COMMON FOLLOW-UPS

Is the average woman 5 feet 4 inches?
That is a rounded shorthand. The official mean is 63.5 inches, which equals 5 feet 3.5 inches.

Yes. The CDC report includes age-group measurements, and this calculator uses separate height percentile curves by age decade rather than one curve for every adult.
