We all have pop cultural associations with particular decades, but the associations we have don’t necessarily match up with the calendar.
I’ve always thought that the associations one has with the Fifties–innocence coupled with Cold War paranoia, the advent of Rock and Roll, and the more popular TV shows–would be better defined as somewhere between 1953-1954 (Elvis and the Sun sessions) and 1963-1964 (the Kennedy assassination/the Beatles arrive in the US).
As for the Sixties, let’s say from 1963 to 1973 (Nixon resigning, US withdrawal from Vietnam).
Seventies: 1973 to around 1982, when the recession ended, MTV debuted, and John Hughes started directing.
Eighties: 1982 to 1991, when the next recession started, Bush v.41 began floundering, and Nirvana released Nevermind.
Nineties: 1991 to Sept. 11 2001.
Going backwards from the Fifties:
Forties: 1941-1952, with 1 1/2 year interregnum (wars hot, cold, and hot).
Thirties: 1929-1939, with another interregnum while the US was waiting for the war to come to it.
Twenties: 1919-1929.
Teens: Not too sure here, but I’d assume something like 1909-1918 (Post-Roosevelt, pre-war era).
Naughts: 1901-1909 (era of Roosevelt and the Progressives).
