Where 1951 sits
1951 is early Baby Boomer: the early third of Boomers runs 1946 to 1952. Pew Research Center range, and the one generation with an official definition: the US Census Bureau uses the same 1946 to 1964 birth-rate boom.
Baby Boomers are the cohort born from 1946 to 1964, the years of the postwar surge in births. It is the only generation with an official definition: the US Census Bureau uses the same range, because it is measurable. Births jumped from about 2.9 million in 1945 to 3.4 million in 1946, passed 4 million in 1954, peaked at about 4.3 million in 1957, and stayed above 4 million until 1964. Roughly 76 million Americans were born in those nineteen years, and their size has shaped every institution they passed through, from overcrowded elementary schools in the 1950s to the strain on Social Security today.
