The ergodic theorems of demography describe the properties of a product of certain nonnegative matrices, in the limit as the number of matrix factors in the product becomes large. This paper reviews these theorems and, where possible, their empirical usefulness. The strong ergodic theorem of demography assumes fixed age-specific birth and death rates. An approach to a stable age structure and t...

demographic analyses of dubas bug, ommatissus lybicus de bergevin, (hemiptera: tropiduchidae), reared on five date palm varieties (zahdi, mazafati, piarom, khasi, and shahani) were constructed under laboratory conditions at 27±1ºc, 70±5% rh, and a 14:10 hours (l: d) photoperiod. data were analyzed based on the age-stage, two-sex life table theory to take the variable developmental rate among in...

ethiopia's childhood mortality has continued to decline although at a swift pace. the drop in urban childhood mortality decline, duration of breastfeeding is the principle reason for the overall decline in mortality trends in ethiopia.  data from the ethiopian demographic and health surveys 2000 and 2005 were used. indirect estimation of brass and trussell's methods were adopted. selected demog...

In this paper we present an agent-based model of the dynamics of mortality, fertility, and partnership formation in a closed population. One of our goals is to bridge the methodological and conceptual gaps that remain between demography and agent-based social simulation approaches. Model construction incorporates elements of both perspectives, with demography contributing empirical data on popu...
