Most of Westport was built recently: 0.8% of its homes predate 1940 and the median home dates from 1981. Below: maps from 1958 on and the census since 1970.
The city is much newer than most towns in northeast Oklahoma. It was incorporated in the mid 1960s, after completion of Lake Keystone. Most of the residences were built between 1960 and 1979. Its first Federal census reported 146 residents in 1970. The census population previously peaked at 325 in 1990, then dropped to 264 in 2000, perhaps because of major damage inflicted by an F4 tornado that occurred as part of a major tornado outbreak. Both subsequent censuses have reported gains. Over 96 percent of the employed residents commuted to work in Stillwater or Tulsa.
