Without the Baby boom, what's the population if the US by 2016?

Fairly straightforward, say that the Baby boom is averted( earlier birth control, no World War two, whatever as long as it averts Baby boom) what would the population if the US be by 2016?
 
When I checked the annual population growth rates within the United States from 1900 I noticed the United States experienced population growth rates of less than 1% from 1930 to 1941, no doubt due to the Great Depression. The birth rate went up after 1941 but it did not spike during the baby boom period except in the years 1947, 1950 and 1957. Population growth plummeted to under 1.5% for most of the years since 1962 and below 1% in 1969, between 1973 and 1976, between 1980 and 1989, between 1994 and 1999 and for most of the 21st Century thus far.

The baby boom wasn't a baby boom at all. It was the population growth rate returning to pre-Great Depression levels. If the Second World War didn't happen the United States population growth would've remained low until the United States had recovered fully from the Great Depression which would've lasted a lot longer than in our time line. It's quite possible that by the time the effects of the Depression had worn off that the contraceptive pill would've entrenched the low population growth rate.

So what would the population be in this scenario? About 250 million.

It wasn't just the Depression. Immigration was closed off for the most part in the mid-20s and that played a role as well.
 
The Baby Boom was driven primarily by older women who had delayed pregnancy during the Great Depression / World War II finally having children once their husbands returned from war/the economy stopped being terrible. The Baby Boom ended once average age of childbirth declined to pre-Great Depression levels. The best way to prevent the Baby Boom would be to have an earlier Great Depression so that a larger cohort of women are simply too old to have children once the crisis ends. Alternatively, you could have a longer WWII for similar effect (or no WWII, as you suggest in the OP, though one doubts that the Great Depression could have lasted forever).

Another thing to keep in mind when calculating a Baby Boom-less population is the Echo Boom that resulted from it from the late 70s to the mid 90s. The "Millennial" Generation will be much smaller in this TL as there will be less Boomers to give birth to them in the first place (and the Echo of the Echo, as in the wave of Millennials beginning to have children that's starting right now IOTL will probably be much smaller too).
