Earliest election every living generation could vote in.

[Oswald Acted Alone, You Kook]

I feel like doing this. Keeping in mind the voting age was 21 until 1972.

The earliest election the Greatest Generation could vote in was 1924, and all of them could vote in 1948 unless they were born in the latter part of 1927, in which case they voted in 1952.

The earliest election the Silent Generation could vote in was 1952, and all of them could vote by 1968.

The earliest election the Baby Boom Generation could vote in was 1968, and all of them could vote by
1984.

The earliest election Generation X could vote in was 1984, and all of them could vote by 2000.

The earliest election the Millennial Generation could vote was 2000, and all of them could vote by 2016.

The earliest election Generation Z could vote in was 2016, and all of them will be able to vote in 2032.

We don't know for sure when Generation Alpha will end.
