Most of Dyer was built recently: 0.9% of its homes predate 1940 and the median home dates from 1997. Below: maps from 1951 on and the census since 1900.
Dyer was platted in 1884 by G. E. Dyer soon after the Little Rock and Fort Smith Railroad was extended to that point. The community has the name of the local Dyer family; S. M. Dyer bought the town site in 1870. A post office has been in operation at Dyer since 1885.
