How is the unit of observation formally/technically defined? How does it get defined in the data documentation?

The scanners can devide between children and grown ups by size. We guess that small grown ups are categorized as children by the algorithm. In the dataset we downloaded, the distinction is not made, but all pedestrians higher than 90cm are counted as a +1. 

It remains unclear, wether people in a wheelchair, carried children, buggies etc. are categorized.

The hours under observation start at X:00 and end at X:59:59. The data from the scanners come in every few minutes and are then commulated for the whole hour.
