Abstract
The level of analysis in demography is generally the aggregate: the size and composition of the population. Much of demographic research addresses issues at the level of population and tries to explain and forecast changes in population size and composition by identifying statistical associations between the behaviour of the population system and other characteristics of the population and the economic and sociocultural system. An example of this system-level mode of analysis and explanation is the theory of demographic transition. Most demographic models, including the life table and the projection models, study demographic patterns at the system level. Multistate demographic analyses also belong to this mode of analysis. Multistate analysis distinguishes different subpopulations and the level of analysis is the subpopulation.

The distribution of the ratio of first marriages in each age interval to person-years lived in the interval. First marriage frequencies are defined as the number of first marriages in an age interval divided by the number of women (regardless of marital status) in the interval (Coale, 1971, p. 196). The sum of first marriage frequencies is the proportion ever-married.
The first marriage density (frequency) is also shown by Coale and McNeil (1972, p. 745); the first marriage rates (risks) are shown by Coale (1971, p. 204).
The logit is the log of the odds in favour of still being married at a given marriage duration. The logit varies between 7 in the first year, when the proportion of marriages dissolved by divorce is very small, to 1.4 after 10 years of marriage, when about 20 percent of the marriages ended in a divorce.
