How many years is a generation?

Answer 1

The challenge here is the birth order of the child. If you are descended from a long line of first born children, 25 years is a good average to use. If you're descended from the babies of the family, then 35 years is more appropriate.

As a working estimate, use a between 25 years and 35 years to a generation. A child born in 2000 should have his father born around 1965 to1975. His grandfather should be born around 1930 (35 years/generation) to 1950 (25 years/generation).

The further back in time you go, the more inaccurate this kind of guesstimate becomes. If you try to calculate a great great grandfather from a child born in 2000 you have between 1860 (35 years/generation) and 1900 (25 years/generation).

Answer 2

It averages 33 years for men, 31 for women in the last 6 generations of my family tree. Most people have most of their children between the ages of 20 and 40; 30 is a good number for estimating.

Measured from a person's birth to his/her first child, it is anywhere from 14 to 24 years, usually; from birth to the last child, it is 40 - 45 years. Once in a while you get oddities. If a man ("Albert") marries a second time and has a son ("Bertram") when he is 60, and that Bertram does the same, that third son, ("Charles"), will have a grandfather who was born 120 years before he was.

Answer 3

I would guess about 20 years.

It seems the generations overlap slightly. I'm at the tail end of "Generation X" I think (1975). My parents are "Baby Boomers" (1950). Their parents I guess are Ted Koppel's "Greatest Generation". That puts you back about 60 yrs or so to World War II.

Isn't "Generation Next" the one which follows "Generation X", or was that just a Pepsi ad campaign?

I've heard of a "Generation Y", but I think that's just a bit younger than Gen X. So it doesn't apply to GenX-ers kids. Or does it.

Was that helpful?

Here's another tidbit. My Great Uncle compiled a genealogy of my family name starting in 1630 or so. I'm the 10th generation since then. The math gives you about 30 years per generation.

Answer 4

Some people believe that a generation lasts 30 to 40 years, I believe a generation last eternally, I am the 2ND generation to my mother and my daughter is the third generation to my mother but my daughter is the second generation to me, so I think its on going. That's just my interpretation of generation.

Answer 5

One generation time is for humans approximate 30 years. For some bacteria 20 minutes when ideal breading temperature and medium provided.

Answer 6

Approximately 30 years.

Answer 7

it depends on the coutry you are living into. I'd say the average gap time between relatives and their newborns.
In italy I'd say it's about 30 years.

William Strauss and Neil Howe, in their book Generations, list the generations of Anglo-America. Their definition of "generation" is given as a cohort-group, in which are all persons born in a limited span of consecutive years, whose length approximates the span of a phase of life given to be approximately 22 years, and whose boundaries are fixed by peer personality. Peer personality generational persona recognized and determined by common age location, common beliefs and behavior, and perceived membership in a common generation.

Answer 8

24 years.

Answer 9

About 20 I would guess. The average age between a parent and a child.

Answer 10

the term of years, roughly 30 among human beings, accepted as the average period between the birth of parents and the birth of their offspring.
