What this average describes
CDC’s summary reports 68.9 inches. Multiplying by the exact 2.54 centimeters per inch gives 175 cm after rounding. This is a measured population average, not a recommended or ideal height.
The country, age group and survey period matter. This result does not describe every country, every age group or the average person worldwide. A selected list of athletes or celebrities cannot stand in for a population survey.
An average describes a group and is not a prediction of any individual’s height. You can compare an entered height with this dated US reference without treating the result as a health assessment.
