There are basically two definitions of baby boomers. The US birth rate was fairly high during most of its history but was low during the years of the Depression and 2nd World War.

1. One def. is for people born between 1946 and 1955--the first decade after WWII. Some parents have children over more than one decade, but this period essentially captured returning soldiers and wives anxious to start families after the disruption of the war.

2. The other definition is more demographic. The US birth rate really took off after WWII. But it continued high among native-born Americans until about 1964, when it started to drop; probably due to the widespread adoption of the then-new birth control pills. Today the US birth rate remains low among native-born Americans but is higher overall due to new immigrants, who tend to be in their child-bearing years and from backgrounds [such as Hispanic Catholic] that encourage large families.

Astrologically, there is no "baby boom generation" that accurately brackets either definition.

Pluto entered Leo in 1938, well before the end of WWII and the start of the baby boom by either measure. It exited Leo in 1957-58 and stayed in Virgo until 1971, well after the noticeable decline in birth rates.

The other outer planets don't match up much better in terms of bracketing either definition of the baby boom.

Neptune entered Libra in 1942-43. From 1955 to 57, it went retrograde back and forth, finally staying in Scorpio in 1957.

Uranus entered Gemini in 1942, finally exiting in in 1949. It first entered Cancer in 1948, finally leaving in in 1956.

One might stretch baby boom definition #1 a bit to allow for a 12-year period of post-War family creation ending around 1957-58 with sign changes for Pluto, Uranus and Neptune. No problem with that, but then the start dates are still significantly off 1946 (the war ended in May, 1945... plus 9 months gestation!)
