What is the population trends (in percentage %) on the generation
split in United States of America?

Please provide this information in a column graph if possible.

Generation split: Generation Y (born between 1978 & 1994), Generation
X (born between 1965 & 1977) and Baby Boomer (born between 1946 &
1964)

Hi! Thanks for the question.


The classifications of age range for different generations are quite
liberal and depend on the different sources available. Furthermore, if
we go by the Census estimates there seems to be an overlapping of the
ages you mentioned. Right now the US Census is a good source for
reliable estimates.

Based on 2005 estimate figures we can see the following numbers below.
Please take note that I re-classified them so as to avoid overlapping
of ages but it will be in such a way that it will still properly
represent the range of each generation.

2005 Estimates from the US Census:

Generation Y (Ages 10 to 24): 62,934,592
Generation X (Ages 25 to 39): 61,144,866
Baby Boomer (Ages 40 to 59): 82,696,453

Percentage of Generation Splits
Gen Y: 30.44%
Gen X: 29.57%
Baby Boomer: 39.99%

I made a graph for you at the link below.

Quick turn around for answer and good result

I find these numbers interesting because there are only 1.4% more baby
boomers per age than Gen Xers.. and there are more Gen Yers than
Boomers per age.  (Note that the boomer generation covers 20 years and
X, Y only cover 15 years each, that is why Boomers look so much larger
than the others on the surface.)

Have a lot of Boomers already died or is the boomer phenomenon not
really that big of an issue?
