the.com/distribution

means The way a whole amount is divided, spread, or arranged among its parts — whether that's income across a population, data across a range, or packages across a country.

from From Latin distribuere — dis- ('apart, separately') plus tribuere ('to assign, allot, give'), the same tribuere that sits inside 'tribute' and 'contribute,' both carrying a sense of handing things out to the tribes (tribus) of Rome. So distribution has always meant a careful dealing-out, long before it meant delivery trucks or bell curves.
