Instantaneous rate  (INSTANTANEOUS rate)


Demographic indices (136. 1) will in most cases relate to a particular period of observation1; this is true in particular of most rates (133-4). An annual rate2 will relate to a period of twelve months. Where observations are collected for a number of years and then averaged, the term mean annual rate3 is often used for the result. Where rates are calculated for periods different from a year they are often converted to an annual basis4 through multiplication by an appropriate factor. Instantaneous rates5 are sometimes computed; they relate to an infinitesimal period of time, cf. for instance the instantaneous death rate (432-4) or the instantaneous rate of population growth (701-1).
