From the archives of the StarTribune, this cartogram depicting the number of households having electricity in each state:
How each state ranks may be judged by its size as shown on the map, which was prepared by the General Electric company, Schenectady, N.Y., from data compiled through a national survey made by the commercial service section of its publication bureau.
New York ranks first, having an electrical population (served by central stations) of 8,620,700, or 78.7 per cent of its actual population. The second largest state is Pennsylvania, with an electrical population of 6,330,000, or 68.8 per cent of the actual population; third, Illinois, with 5,150,000, or 79.8 per cent; fourth, Massachusetts, with 4,030,000 or 97.8 per cent; fifth, Ohio, with 3,550,000, or 66.1 per cent, and sixth, California, with 2,827,000, or 86.5 per cent.At the bottom of the list is Nevada, squeezed into a tiny circumference on the map, because it has only 66,300 persons served by central power stations, which, however, is 54.3 per cent of its actual population...The electrical population of the United States is 62,023,400, out of an actual population (last previous census) of 108,148,000, a percentage of 57.3.
This was of personal interest to me because my father used to work for REA (the Rural Electrification Administration) in the 1950s.
