No two persons are equally likely to die in the next year; no two marriages are equally likely to be broken up by divorce; no two businesses are equally likely to fail; no two automobiles are equally likely to break down. That on the average a given make of automobile will travel 50,000 miles without major repairs offers little assurance for any particular automobile. Averages can be applied to individual cases only at great risk. This gross aspect of heterogeneity is not the subject of the present chapter. date: 1985 date_type: published publisher: Springer id_number: 10.1007/978-1-4757-1879-9_14 creators_browse_id: 2026 full_text_status: none series: Springer Texts in Statistics place_of_pub: New Yok, USA pagerange: 385-399 refereed: TRUE isbn: 978-1-4757-1879-9 issn: 1431-875X book_title: Applied Mathematical Demography coversheets_dirty: FALSE fp7_type: info:eu-repo/semantics/bookPart citation: Keyfitz, N.
