Demography and vital statistics

Summary - Demography and Vital Statistics

The multilingual dictionary of the International Union for the Scientific Study of Population (IUSSP) defines demography as the scientific study of human populations primarily with respect to the quantitative aspects of their size, structure, and development. Demography uses population censuses, vital statistics, administrative records, and surveys to produce information for characterizing migration (internal and international), as well as fertility and mortality, mainly within national territory. The results are used in further analyses and studies and in the creation of public policies.
Since the early 2000s, Chile has been in a stage of increased aging of its population, with a fertility rate below the replacement rate (its total fertility rate less than 2.1), a low level of mortality, and a sustained increase in life expectancy at birth. The population projections based on the 2017 Census show that these phenomena will intensify over time, leading to a projection of 176 persons over the age of 64 for every 100 persons under the age of 15 in 2050.
The increase in international migration is worldwide phenomenon. Chile has become an important destination of migration as can be observed in data from the census and from administrative records.
