Very few of my same-age friends have a real telephone with a listed number in their home. (I would love to see actual statistics for cellphone-only households by age group.)
I was thinking about this tonight when I participated in a quick political phone survey gauging the prospects of the candidates for Mayor of Boston, seeking vague [meaningless?] opinions on the “direction” of the city, and asking for whom I would vote for US Senate if the election were held today. Surely my age group is severely under-represented in public opinion polls. How well can you actually control these studies to represent the true population? The only personal question they asked was for my highest level of education.
