## The Blockade’s Human Arithmetic
When historians write about the Berlin Airlift, they tend to emphasize the tonnage figures. Those numbers are genuinely extraordinary. But the blockade’s impact on individual Berliners was experienced not in aggregate tons but in the daily arithmetic of what they had and what they needed.
A West Berliner in the summer and fall of 1948 woke up in a city with unreliable electricity, limited fuel for cooking and heating, and food provided through a rationing system that depended on aircraft to function. The initial daily ration of 1,600 calories per person was set by nutritional planners as the minimum for sedentary adults. Workers doing manual labor needed more. Children needed different proportions of nutrients. Elderly people on fixed circumstances faced the same deprivation as everyone else. The ration was not starvation, but it was not adequate, and it was what the airlift was straining to maintain.
Coal was the other critical commodity, and in some ways more urgent than food during the blockade’s winter phase. Coal heated apartments, powered the city’s remaining industrial activity, and ran the electricity-generating stations in the Western sectors. The Allied-controlled power stations were not sufficient to cover the city’s full needs even before the blockade; with Soviet-controlled stations cutting their output to West Berlin, the electricity shortage was acute. The rolling blackouts that characterized daily life in West Berlin through the winter of 1948 and 1949 were not inconveniences. They determined when food could be cooked, when children could do homework, when workshops could operate.
