We examine subjective income security among Canadians aged 45 and over, usi
ng quantitative data. We examine the relationship between demographic, soci
o-economic and social-psychological variables and income security, measured
in multivariate analyses as the likelihood of dissatisfaction with current
and expected future income. Our discussion is focussed on several unexpect
ed findings related to the effects of age, marital status and gender on sub
jective income security. Five social-psychological theories - aspiration th
eory, reference group theory, equity theory, the life review, and socializa
tion/identity theory - may help to account for these findings. While the th
eories cannot be tested using these data, they provide directions for futur
e research in this area. We conclude that subjective evaluations of income
adequacy ought not to be the means by which social policies on income redis
tribution are determined.
