[[A treatise on sex ratio in population by marital status: marriage squeeze and widowhood]].
"This study deals with imbalances of sex ratio in population by marital status, particularly focussing on two important demographic problems in Japan...the first relating to an excess of male population in marriageable ages and the second relating to an excess of [single, widowed, or divorced women] in the middle and old ages.... Population ageing [of] unmarried women, whether never married, widowed or divorced, [is examined]....Tables of [the] family life cycle have been constructed for Japanese couples for the periods 1920 to 1985, particularly specifying lengths of widowhood and widowerhood."
