Every couple of years, there is a weighing programme. I recall being in South Africa when there was voluntary weighing of pax. Sine this was for a regular 737 type internal flight of 1,000 miles I naturally picked up the leaflet.
The SA airports were weighing pax (self-selected) across a range of flights to see what their weights were. This information was then sold to other airlines to enable them to update their average weights. The leaflet said that this was done around the world at various times to measure long term trends in various populations.
I stood on the scale and my weight was not visible to anyone, the computer simple noted it. My bags were weighed as normal.
It is not just the the citizens of the USA that are large and carry lots of bags, travelled by air in Africa ??
