After 1910 steady population decline was driven by the lack of significant population in outlying areas, migration to larger urban centers, and the absence of dynamic economic factors to generate wealth. The hardware store closed in 1928 and the bank, like thousands of other undercapitalized small-town banks in the United States, went out of business in 1929 or 1930 in the aftermath of the stock market crash of 1929. U.S. Census bureau data indicates that the population fell to 102 in 1920, 80 in 1930, rose slightly to 89 in 1940, and fell to 62 in 1950, 35 in 1960 and 24 in 1970. As local establishments burned down or went out of business they were not replaced, and finally the post office was discontinued in 1980 when the census bureau pegged Tenney's population at 19. Today the only remaining business in town is the elevator. The only commercial building remaining on the main drag is the former James Bigsby general store, later the G.A. Klugman general store, which also housed the post office until its closing in 1980. The building was vacant for several years, but was recently purchased and is being rehabilitated.
