Firstly. 65-76 isn't a bracket on the poll.
Uh, that's the point. The sample size would likely be really small.
I do see that it could be part of the reason......but I don't believe for a second that 22% of the population disappears between 18-29 and 30-44... and then another 27% would have to die in 45-64....which is what would be the case if your explanation was the true explanation.
Its just poor practices by pollsters.
Here's the age demographic census data for 2000, from Wikipedia:
Roughly 60 - 65 million people in each age bracket, except for 65+, where there are only 35 million people. But besides just having enough people to poll, the age brackets are based on voting trends for people in approximately the same stage of life, who will have similar values (theoretically). 18 -29, young adulthood, likely single and starting their careers; 30 - 44, established careers, married and having children; 45 - 64, middle age and preparing for retirement; 65+, retired.
You can fudge it with a year or two here and there, but basically a 75-year-old isn't going to have a wildly different worldview from an 80-year-old or a 65-year-old. While a 25-year-old and a 35-year-old are often in very different stages of life.
